Difference between animal pollinated flowers and water pollinated flower

Explanation:

Insect pollinated flowers have features that allow insects, birds, or other animals to pollinate them when they feed on the nectar. The pollen grains will stick onto the outer covering of the insect and when the insect brushes past the stigma of the same flower or another flower, the pollen grains will stick onto the stigma of the flower and pollinate the flower. the pollen grain will then grow a pollen tube down the style to reach the ovary which contains the ovules, and when the two sex cells fuse, fertilisation will take place and the ovule will develop into a seed and the ovary a fruit.

To maximise the chance of fertilisation taking place, insect-pollinated flowers usually have:

*Large, scented and brightly coloured petals to attract pollinators

*Filaments and anthers inside the flower

*Stigma(s) inside the flower

*Large and sticky/spiky pollen grains

*Small and a sticky stigma

*Nectar for pollinators to feed on

Examples of such flowers are rose, hibiscus, sunflowers, etc.

On the other hand, wind-pollinated flowers do not need pollinators as the pollen grains fall off when the wind blows past onto the stigma.

Wind pollinated flowers usually have:

*Small and dull coloured petals

*Filaments and anthers hanging out of the flower

*Stigma(s) hanging out of the flower

*Small and dry pollen grains

*Large and feathery stigma to catch the pollen grains that are blown off

*No nectar

Answer 2

Answer:

water pollinated flower- • the Pollen grains are also covered with a protective waxy layer which prevents them from getting damage by water.

•For example, Vallisneria is pollinated by water.

Animals pollinated flower- • this flowers produce sticky or spiny pollen grains that take to the body of insects and are carried by them.

•Example: pollination in sunflower etc.
