Why Is Pollen So Important

In order to reproduce, plants need to be pollinated, and this is the reason that they produce pollen. Without pollination, plants will not produce seeds or fruit, and the next generation of plants. For us humans, pollination is so important because it is how food is produced.

What plays important role in germination of pollen?

RNA and protein synthesis are important for pollen germination in all studied plants, as indicated by the effects of actinomycin D and cycloheximide, respectively. Pollen grains germinate in the presence of actinomycin D, but further tube elongation is suppressed.

What happens when pollen germinates?

When the pollen grain germinates on the stigma it creates a burrow called the pollen tube as it travels toward the ovary. When the sperm cell from the pollen grain reaches the ovary or ovule the sperm joins with the egg. This is called fertilization. The fertilized zygote will become a tiny new plant inside the seed.
