Why are wind pollinated flowers not usually brightly colored?
Wind-pollinated plants do not need colorful flowers as they are not pollinated by animals, insects or birds. Since wind-pollinated plants do not need colorful flowers, they might as well put their energy into making their pollen lighter, or more of it.
How flowers leaves and stem help plants meet their basic needs?
Flowers are the parts that get pollinated so a plant can produce seeds for reproduction. Leaves carry out photosynthesis, which is how the plant makes food. The stem stores nutrients, and waste for the plant. Roots bring in food, water, and other nutrients into the plant.
What are characteristics of water pollination in Vallisneria?
Water pollination in Vallisneria includes the release of male flowers that float to the surface, where they release pollen. The pollen is then carried by water currents to reach the female flowers, which are anchored underwater. This method allows for effective pollination in submerged aquatic environments.
What are the agents in pollination?
Agents of PollinationIntroduction of agents of pollinationWhen the pollen grains are shed from anther, they are disseminated by arios agencies. Some of them may, by one means or another, finally reached the stigma of a pistil, either of same or another flower. This transfer of pollen from anther to stigma is called pollination. Agents of pollination are wind, water, insects, birds and bats. Description of Agents of PollinationWind (anemophily): Wind is one of the most important agents of pollination. Pollination brought about through agency of wind in plants is called anemophily. Wind pollinated plants are coconut palm, date palm, cannabis, maize, grasses etc. exhibit the following characters which favour the wind pollination.a) Wind pollinated flowers are inconspicuous and not showy.b) They are devoid of scent, nectar etc.c) The pollen grains are dry and unwettable.d) The anemophilous plants grow in large groups to ensure pollination.e) To catch the pollen grains, the stigma become sticky, hairy, and feathery or branched.2. Water (Hydrophily): Pollination brought about through the agency of water in plants especially submerged plants is termed hydrophily. Examples are Hydrilla, Ceratophyllum, Zostera and Vallisneria are some of the water pollinated plants.3. Insects(Entomophily): Inset pollinated flowers possess following characteristic featuresa) The insect pollinated flowers are fragrant and omit sent and odour. Example Cestrum, Jasmine etc. Rafflesia gives out obnoxious and repelling odour.b) The insect pollinated flowers are beautifully coloured. In flowers, mostly petals are brightly coloured.c) The nectariferous glands produce nectar for feeding the visiting insects.d) To catch the pollen grains, the stigmas become sticky.4. Birds (ornithophily): Ornithophilous flowers differ in number of respects from entomophilous flowers. These kind of flowers are generally scentless. The flowers are usually large in size. They are also beautifully coloured with colour contrasts and are common colours liked by birds.5. Bats (Chiropterophily): The flowers of Kigella pinnata, Durio, Antocephalus are pollinated by bats. The bats hold on to the freely exposed, large and relatively tough flowers, which open in the evening or night. Bats are nocturnal animals and transport pollen over long distances. They usually give off a strong scent like that of rotting fruits. Bats also feed on the copious nectar and pollen which is produced in plenty as compared bird pollinated flowers.
Why is it that some plants have brightly colored flowers and other do not?
to attract bugs to land on it. After landing on the flower pollen will stick to the bugs feet, so then when the bug lands on another flower, it will pollinate it. That is one way of how flowers reproduce sexually.
Why does water mil foil have flowers that form above surface?
Water milfoil is a flowering plant despite living in water. Its flowers need to be pollinated in order for it to make seeds. It is wind pollinated so the flowers need to be above the water.
Does flowers have insect pollinated flower?
Flowers are structures on a type of plants called angiosperms, which usually exploit a strategy involving a flower, called biotic pollination which requires another organism (vector) typically, although not always, an insect. By contrast, abiotic pollinators like grasses and conifers would use other means like wind or rarely water to effect pollination. Biotic non-insect pollinators may rely on birds or bats for transport, but the great majority of pollen vectors are insects.
Why are wind pollinated flowers not usually brightly colored?
Wind-pollinated plants do not need colorful flowers as they are not pollinated by animals, insects or birds. Since wind-pollinated plants do not need colorful flowers, they might as well put their energy into making their pollen lighter, or more of it.
How are petals on flowers different from flowers pollinated by animals?
Animals must find and eat food, whereas plants create their own food, using the sun's rays and water.
Who do water lilies reproduce?
Just like any other flower, the flowers get pollinated by bees, hummingbirds, etc. When pollinated, they grow seeds which get blow by wind, go in water, or if an animal eats and digests it, or if it catches in an animals fur. When the seed lands somewhere, they will grow there :)
How does the lotus flower reproduce in detail?
Lotus flowers grow in water in warm areas. The lotus seed falls to the bottom of the water and forms roots, It will send a stem up to the top of the water and form leaves and eventually flowers. The flower is pollinated and the cycle repeats.

Why do flowers pollinate?
The entire purpose of pollination is to perpetuate the species. Pollination is essentially the act of fertilization, so reproduction can take place. Most flowers are pollinated with the assistance of animals, like bees and birds. Some flowers rely only on the wind or water to pollinate.
Why do pond weed flowers grow above the water?
Accessibility to pollinating insects is a reason why pond weed flowers grow above the water. Aquatic plants whose male variety's pollen grains are water-pollinated by a female variety's floral stigmas contrastingly will not need the above-surface flowerings.
How can insect larvae in water be identified?
Insect larvae in water can be identified by their physical characteristics, such as body shape, size, and color. Additionally, their movement patterns and behavior can also help in identification. Using a microscope or field guide can aid in accurately identifying the specific type of insect larvae present in the water.
