Describe each flower structure and its role in plant reproduction. State if the structure is male, female or neither: h. ovules *
Answers
Answer:The male reproductive parts of a flower are much simpler than the female ones. Called stamens, these reproductive organs are made up of two parts: anthers and filaments. The anther is the part of the organ that produces pollen, and the filaments hold up the anthers. There are often several stamens for every one pistil. This is because having multiple stamens increases the number of pollen grains available, which make it more likely than one of the pollen grains will become stuck to the stigma, travel down the style into the ovary, and fertilize the ovules to produce seeds.
How do They Meet?
In order for the ovules in the ovary to be fertilized, the pollen needs to get inside the ovary. How does this happen? Actually pollination can occur in many different ways. Sometimes, the wind blows the pollen towards the pistil so that it gets stuck on the stigma. Other times, an animal brushes by the stamens and carries the pollen on its fur until it falls off near a pistil, or an insect lands on an anther and then lands on the top of a pistil. Remember that not all plants are self-fertilizing, which means that some plants become fertilized by the pollen from other plants, so pollen may travel a long distance before it actually meets up with an ovule to fertilize
