What are the ways in which seeds are dispersed?
Here are different way seeds can be dispersed..1.) After the seeds have formed, they are usually scattered, sometimes far from where they were produced. The scattering of the seeds is called "seed dispersal".2.) Water. Water can disperse seeds that fall into oceans and rivers.3.) Wind. Wind disperses lightweight seeds that often have structures to catch the wind.4.) Some plants eject their seeds, and the force scatters the seeds in many directions.5.) When seeds are mature, the scales open. The wind shakes the seeds out of the cone and carries them away. Only a few seeds will land in suitable places and grow into new plants.6.) Fruits are the means by which angiosperm seeds are dispersed. Animals that eat fruits help to disperse their seeds.=======================By wind - most grasses use this way;by animals - most plants with brightly coloured flowers and edible fruits; andby water - e.g. coconut=======================The 3 means of seed dispersal are the wind, theres also the birds and other critters eating the fruit or nut and then defecating the seeds in another spot. Also water carrying the seeds from the plant they originated from to another spot.=======================Seed can be dispersed in various manners; this is normally dependant on the physical characteristics of the seed or seed coat or the fruit containing the seed.Seed dispersal is necessary to move plants to new locations, this reduces overpopulation and competition for resources in the same location, dispersal also extends the physical range of the plants into new ecological regions. Indirectly it improves the chances of the new plants being able to interbreed or improve the gene pool of the particular plant, plants grown in very isolated or specific closed regions have very little genetic diversity and are cannot cope with sudden threats to their existence.The agents or mechanisms of dispersal are also known as vectors of dispersal.Animals: Seed contained in edible fruit (e.g. figs, tomato, mango, berries) can be distributed by animals which eat the fruit and then eventually excrete them in another location. Examples: Bats, monkeys, squirrels, cattle, wild herbivores.Insects: Many insects collect seed for food (ants, termites etc.), the seed is then taken back to the nest where it may germinate or be dropped and germinate.Wind: Certain seed is adapted to dispersal by wind; these normally have a wing or similar appendage that allows the seed to be carried by air currents. Examples, pine seeds (wing), Acer seed (wing), Maple and Dandelion.Gravity: Certain seeds are heavy and rounded in shape, this facilitates the seed falling from the seed pod and rolling a distance from the parent plant.Burrs and hooks: Certain seeds have burrs, hooks or thorns, the aim of these is to attach themselves to the skin or fur of a passing or foraging animals (or clothes in the case of humans); the animal then moves to another location where hopefully the seed drops and germinates. Examples include: Burdock and Foxtail.Mechanical/ Explosive dispersal: Some plants have "exploding" pods that physically throw the seed away from the parent plant. Examples of these include: Impatiens/ Balsam and some legumes.Water: Some seeds, particularly of plants that grow close to the coast or rivers are adapted to float in order to be distributed away from the parent. Most water plants employ this method of dispersal. Examples are Coconuts, mangrove plants and Lotus.Fire: While fire per se is not a method of dispersal it is a key factor in releasing seed (or breaking seed dormancy) of some species that otherwise would not be able to be released or germinate. Examples include Protea, Erica, certain Pines and some Banksia species.Once you know what the shape and characteristics of the seed are, you can use the above information to determine how the seed is most likely dispersed. Cherry has a stone and a fruit sweet fruit covering, so it is most likely dispersed by animals, birds, bats or even gravity.=======================Gravity , where the seed drops to the ground -wind , where the seed is spread by air-born forces (Think of a Dandelion seed.) -water , which can carry the seed downstream - animal , where the seed can be carried in fur or through animal droppings -humans , where the seed can be spread through planting ~ the related link below will provide more information regarding seed dispersal .=======================1.Disperse seeds by water.2.Disperse seeds by wind.3.Dispersal by animals.4.Some plants eject their seeds.=======================1. Wind dispersal: dandelions have fruits with parachutes of hairs that catch the wind and are blown about. Sycamore fruits have wings which can be blown about and carried over distances.2. Water dispersal: fruits which float, such as those of the water lily and the coconut palm are carried by water. Coconuts can travel for thousands of kilometres across seas and oceans. The original coconut palms on South Sea islands grew from fruits which were carried there from the mainland by ocean currents. Mangroves in swamp regions in countries such as Thailand are another example.3. Animal dispersal: seeds of juicy fruits are carried by birds and other animals. The fruits are eaten, but only the juicy parts are digested, but only the juicy parts are digested. The stones and pips leave the animal's body via the droppings which may be some distance away from the parent plants. e.g. blackberry, cherry and apple. In the case of mistletoe, the sticky fruits are eaten by birds which then clean their beaks on the bark of trees, leaving behind a sticky seed which can grow into a new mistletoe plant on the tree. (Mistletoe is a plant parasite). Small seeds can be carried on the feet of birds and other animals. Fruits with hooks and barbs, e.g. the burdock fruit are carried in the hair, fur and wool of animals. Squirrels bury nuts, including acorns, for food supplies over the winter, but sometimes leave some behind which may grow into new plants in the spring.4. Explosions: some plants disperse their own seeds. The pods dry and split open suddenly with some considerable force which throws their seeds for some distance. e.g. laburnum, broom, peas.=======================Seeds can be dispersed usingwind;animal vectors such as birds which disperse the seeds in their droppings, or animals that disperse the seeds by transporting them stuck to their fur;explosive seed pods. Some seeds are exploded from a ripe seed pod;Well, it would be more helpful if you could be more specific as seeds can be dispersed in many more ways than one! There is wind, where the seeds if light enough are carried away be it. Animals could eat the seeds and disperse of it else where in it's dung.
What are three adaptations that help angiosperms on land?
Leaves and stems have waxy coverings to prevent water loss. Stomata are only open when there is available water. Land plants have vascular tissue that allows them to transport water and nutients. Seeds and pollen are made to survive longer periods of time in harsher conditions.
What are the 3 main categories of adaptations?
The three main categories of adaptations are structural, behavioral, and physiological. Structural adaptations refer to physical features that help an organism survive, behavioral adaptations relate to actions or behaviors that aid in survival, and physiological adaptations involve internal changes that enhance an organism's chances of survival.
What are the stages of sexual reproduction in flowering plants?
The stages of sexual reproduction in flowering plants are: pollination (transfer of pollen to the stigma), fertilization (fusion of sperm and egg cells), seed development (formation of a zygote and embryo inside the ovule), and seed dispersal (spread of seeds to new locations for germination).
What did Mendel observe in the F2 offspring that showed him that the alleles for seed shape segregate independently of those for seed color?
Mendel observed a 9:3:3:1 phenotypic ratio in the F2 offspring, where the traits for seed shape and seed color were independently assorted from each other. This suggested that the alleles for seed shape (round/wrinkled) were segregating independently of the alleles for seed color (yellow/green).
What are 3 plant adaptations that live in the estuary?
Salt tolerance: Many estuarine plants have adaptations that allow them to tolerate fluctuating salinity levels, such as specialized root structures for absorbing water and excluding salt. Aerial roots: Some estuarine plants like mangroves have specialized aerial roots that enable them to survive in waterlogged soils by providing oxygen and support. Seed dispersal mechanisms: Estuarine plants often have adaptations for dispersing their seeds in the tidal environment, such as buoyant fruits or seeds that can float on water to reach new habitats.
What are wind water and living things are 3 means of?
Wind, water, and living things are three means of seed dispersal in plants. Wind can carry seeds over long distances, water can transport seeds downstream, and living things such as animals can scatter seeds as they move around. These mechanisms help plants colonize new areas and increase genetic diversity.
How big is a sycamore seed?
A sycamore seed is typically about 1 to 1.5 inches long, with a distinctive wing that can extend the seed's overall size to around 2.5 to 3 inches when fully spread. The winged structure helps the seed to be carried by the wind, aiding in its dispersal. These seeds are often found in clusters and are shaped somewhat like a helicopter blade.
How is a seed formed in 3 steps?
A seed is formed through three main steps: fertilization, seed development, and maturation. First, fertilization occurs when pollen from the male part of the flower (anther) transfers to the female part (stigma), leading to the fusion of sperm and egg cells. Next, the fertilized ovule develops into a seed, forming a protective seed coat and storing nutrients. Finally, the seed matures, completing its formation and becoming ready for dispersal to promote germination and growth into a new plant.
What would happen if bats were extinct?
If bats were extinct, there would be negative impacts on ecosystems worldwide. Bats play a crucial role in pollination, seed dispersal, and insect control. Their absence could lead to imbalances in insect populations, reduced seed dispersal for plants, and potential decline in agricultural productivity. Additionally, some bat-dependent species may face extinction due to loss of their main food source.
What plants use water dispersal?
Plants that use water dispersal for seed dispersal include water lilies, coconuts, and mangroves. These plants produce seeds or fruits that can float on water, allowing them to be carried to new locations for germination.

What are the 3 different ways that a seed can be spread?
Seeds can be spread through various methods, including wind dispersal, where lightweight seeds are carried away by the breeze; water dispersal, where seeds float on water and are transported to new locations; and animal dispersal, where seeds attach to fur or feathers or are ingested and later excreted by animals, allowing them to germinate in different areas. These methods help ensure that plants can colonize new environments and maintain genetic diversity.
What are the adaptations of a Trillium?
3 adaptations the Trillium has are:It has big leaves so that while its under all of the tree, it can get the sun it needs.It give out a odor to keep away enemies.It has a lipid rich appendage that attracts ants so it can reproduce.
