What are the methods of pollination?
There are two different kinds of pollination. The two main kinds are self pollination e.g pollen from plant A lands on the stigma of plant A and pollinates the ovules of plant A and cross pollination e.g. pollen from pant A lands on the stigma of plant B and pollinates the ovules of plant B
What does plants grow from?
Pollen grows inside the flower. The pollen acts as a guard for the egg and sperm of the flower. When pollination occurs and the egg and sperm are placed on another plant, fertilization happens to make more new flowers.
What is the process in which pollen from one plant is used?
Pollen that is received from another plant is called pollination. Pollination occurs when insects and animals gather pollen on their bodies and will disperse it while moving around other plants.
Why is the number of petals and sepals in a rose not equal in numbers?
The petals of a flower are for photosynthesis (for energy) and for attracting other organisms (with bright colors) such as birds, insects, and mammals that transfer pollen from flower to flower, a.k.a., pollination, in order to reproduce (also see "cross-pollination). The sepals contain more chlorophyll which gives plants their green color, and are used for protecting the flower while in it's "bud stage". Cross-Pollination: When pollen is moved from the male structure of a flower and carried to the female structure of another flower by wind, insects, mammals, and birds, as well as fish on some occasions.
Why is pollination important to all humans and animals?
Agriculture is highly dependent on plant pollination in order to produce the food we eat. Without adequate pollination less food (if any) will be produced, which means less food to feed more hungry mouths.
What is the different between crosspollination and self-pollination in plants?
Cross Pollination is when the flower/plant is pollinated by other flowers/plants other then its self, unlike Self Pollination which ONE flower/plant can pollinate its self with out other flowers/plants, the more you learn in BIO the more you can see the hand of God in work!
Differentiate cross pollination from self pollination?
Self pollination is where the plant is able to pollinate without another plant. This provides much less variation in the genetics of the species from generation to generation than cross pollination which is where the pollen from one plant is carried to another plant (bees usually do this) and fertilizes the other plant. It creates more genetic diversity because the genes from both plants, which are different, are involved in the forming of the seed, not just the genes from the one self-pollinating plant.--------------------------------------------IMPROVEDSelf pollination is the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone. Cross pollination is the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
Ways pollen can move?
There are three common kinds of pollination: self pollination, wind pollination, and insect pollination. •Self pollination is when the pollen in the stamen (male part of the plant) drops into an ovule (egg) in the ovary of the stigma (female part) of the same plant. This is why it is called self pollination. • Wind pollination occurs in plants that are all-male (its flowers only containing stamen) and all-female (its flowers only containing the stigma). The stamen develops millions of pollen grains in the spring, as the chance of the pollen reaching an all-female plant is very little, and releases it in the summer. The few pollen grains that reach an all-female plant will be likely to reach an ovule in the stigma and pollinate the ovule. • Insect pollination is used by a lot of plants. This method of reproduction is when an insect such as a bee, butterfly, moth, or sometimes a bat, reaches a flower and sucks out the nectar in the flower. As they do this, the pollen gets stuck in their legs, and when they suck the nectar from the flower of another plant, the pollen gets onto the flower and into the stigma. If the pollen from a different type of plant is put into a stigma of a plant, pollination won't occur, so God has designed the bees of each hive to suck nectar from one kind of flower each day, so that the chance of pollination will be more.
Why is it important for wind pollinated plant to produce large amount of pollen?
Because of the greater odds of the pollen finding another flower to pollinate. Insects fly flower to flower therefore pollination is assured. Wind pollination is much more chancy.
Which needs more water a flower or a plant?
A flower is a plant
How does cross pollination happen naturally?
Cross pollination happens when an organism transfers pollen to another flower. Or the pollen could transfer by wind. Bees mostly pollinate flowers we know and other by wind, pollen on our car.
What are the methods of pollination?
There are two different kinds of pollination. The two main kinds are self pollination e.g pollen from plant A lands on the stigma of plant A and pollinates the ovules of plant A and cross pollination e.g. pollen from pant A lands on the stigma of plant B and pollinates the ovules of plant B
What does plants grow from?
Pollen grows inside the flower. The pollen acts as a guard for the egg and sperm of the flower. When pollination occurs and the egg and sperm are placed on another plant, fertilization happens to make more new flowers.
Why are petals sometimes brightly coloured?
Flower petals are bright so insets can be attracted to them to collect the flowers nectar. Once the insects have collected the nectar some of the nectar fall and that's how more flower of the same kind grow. SO SOME TIMES YOU DON'T NEED FLOWER SEEDS TO GROW FLOWER'S.
What is it when a bee collected nectar from a flower?
This actual process has no name, (that I am aware of(Bee-keepers may know more...)) but is one of the stages required for the pollination of flowers. You could say that it is part of the pollination process but it is not essential for all plant life to be pollinated in this way.IT COLLECTES POLLEN GRAINS.
Can pollination in pea plants happen in three ways?
Pea flowers are self-pollinating. About two days before the flower even opens, the anthers at the top of the stamen, which are the male part, burst and release the pollen. This sticks onto the stigma and fertilizes the ovary - these are the female parts. In many flowering plants, the stigma will not accept pollen from the same plant and fertilization must occur through other means, such as insect pollination after the flower opens. For gardeners, self-pollination is an advantage as it means more than one type of pea can be grown close together, as cross-pollination will not occur.
What is the process in which pollen from one plant is used?
Pollen that is received from another plant is called pollination. Pollination occurs when insects and animals gather pollen on their bodies and will disperse it while moving around other plants.
