QUESTION ABOUT PLANTSS!! their structure...etc. please help!?

Question

1. How does a pollen grain get to the stigma of a pistil?

2. how does the structure of the stigma aid in pollination?

Answer 1

1. Pollen grains are distributed many ways. Insects pollinate plants, some plants use wind to disperse their pollen, and birds (like hummingbirds) sometimes aid pollination, too. There are other ways, but I think these three are good enough for your question.

2. A stigma is long and projects itself from the flower far enough to catch pollen grains in whatever way they are dispersed. Some have a sticky substance on its tip to catch the pollen grains and hold them.

Kinda vague, but it's been awhile since I took botany class. Hope it helped!

Answer 2

Good job with the explanation, Kalani.  It's been a while since I taught botany at a university, but you explained it accurately and clearly.
