why water flower no very colourful???
Answers
Explanation:
Wind and water pollinated flowers are light in weight as air and water cannot carry heavy pollens. They are neither colorful nor nectar producing as these are the characters for the insect-pollinated flowers.
hope it helpful
Answer:
Because if we see in the case of terrestrial plants there is need of attracting insect or other pollinators so they are colourful for attracting insect and other pollinators
If we see in the case of hydrophilly plants there is no need of attracting any pollinators;that's why these are not colourful

Why are wind- and water-pollinated flowers not very colourful and why do they not produce nectar?
Why are water-pollinated flowers not colourful and not producing nectar?
What is water pollination?
Water and wind being the pollen carriers of such flowers and not insects, there is no evolved system to attract insects for pollen and nectar. Flowers having colors and nectar would have been a redundant arrangement anyway if pollens are not being transmitted through insects but rather by water and wind. Obviously, nature did not evolve this process among such flowers.
There is an editing and deactivation selective pressure in evolution. An organism can only have a genome of finite size and so information on which there is no selective pressure tends to be lost over time. Nectar is sugar based and costs a lot of sugar (fixed carbon) to make. Pigments also require a great deal of biochemistry and so if they are redundant genes for them will tend to be deactivated and lost. We have no fish scales or reptilian scales even embryonically. More of less all plants have the genes and the biochemistry required for C4 photosynthesis but most plants do not have the anatomy necessary for it to function as a CO2 concentrating mechanism.
Flowers are colorful to attract pollinators, i.e. bees, flies, and butterflies. ( Terrestrial flowers, that is) But, if the plant is water or wind pollinated, there is no need to attract bees or flies or butterflies.
Why are wind- and water-pollinated flowers not very colourful and why do they not produce nectar?
This is true in most cases because wind and water pollinated flowers do not need animals to be pollintionated, so they don’t need to attract animals with colors or nectar.
Why are water-pollinated flowers not colourful and not producing nectar?
They are not dependent on insects or other animals for pollination. In these plants pollination takes place with water currents. There is no need of nectar or coloured flowers as they don’t need to attract any external agents.
What is water pollination?
It takes place in plants growing in water. They are called hydrophytes. Examples are Ceratophyllum , Vallisneria. In these plants pollen grains from the flowers are transferred to the stigma through the agency of water. In this plant ( Vallisneria ) flowers are unisexual. Male flowers get detached fro
Why do insect pollinated flowers produce nectar?
Insect pollinated flowers produce nectar to attract insects , which visit these flowers for nectar only. These insects feed on nectar. While feeding on nectar insects carry pollen along with their bodies and when they visit another flower they affect pollination. In these flowers nectar is produced
Why are water-pollinated flowers colourless and nectarless?
Flowers contain vector and beautiful colours only to attract pollinator like bees , flies and others . Such a property of flower are only present in terrestrial flowers as these properties attract the pollinator for pollination. But in the case of water pollinating flowers the pollination usually ha
Why do bees continually go to the same flower. Do flowers keep producing nectar?
Flowers use different strategies to attract pollinators and get pollinated effectively. They bloom at a certain time of the year to reduce competition. Many produce nectar or pollen only during a short time during the day so that plants practically slice the day up into slots, again reducing competi
