Worksheet Overview

Mrs. Bates's science class had been studying how plants reproduce and also how to use a microscope, so in today's lesson they are going to try growing pollen tubes.

 

In flowers, when the pollen arrives on the female stigma, it starts to grow a tube down towards the ovary in order to fertilize the ovule and form the beginnings of the seed.
