Grasses do not have brightly coloured flowers.how might this be related to the way they they are pollinated
Answers
Answer:
this depends on the amount of chlorophyll or chloroplast they have in them.The colors you see in flowers come from the DNA of a plant. Genes in a plant’s DNA direct cells to produce pigments of various colors. When a flower is red, for instance, it means that the cells in the petals have produced a pigment that absorbs all colors of light but red. When you look at that flower, it reflects red light, so it appears to be red.
The reason for having flower color genetics to begin with is a matter of evolutionary survival. Flowers are the reproductive parts of plants. They attract pollinators to pick up pollen and transfer it to other plants and flowers. This allows the plant to reproduce. Many flowers even express pigments that can only be seen in the ultraviolet part of the light spectrum because bees can see these colors. Some flowers change color or fade over time, like from pink to blue. This informs pollinators that the flowers are past their prime, and pollination is no longer needed.
Most plant species have a flowering-based pollination process in which flowers are used for pollination. But in the case of grasses, pollination takes place differently. Grasses do not have a flowering structure. It is generally of smaller size and not much variation from its family. It has large anthers which stick onto the body of pollinators and with the help of these pollinators, they travel to the stigma of the female part and this results in pollination.
Wind pollination is also an example of pollination in grasses. Some of the grasses are self-pollinated if such type of pollination is compatible with them. Insect-borne pollination can also occur in some rare grasses. So these are the facts which may relate to the pollination of grass which does not have a flowering structure.
