Book 29, Question 38
Why do squash plants have two kinds of flowers?
Squash plants have male flowers and female flowers on the same plant.
Male flowers have a straight stalk, and female flowers have a tiny fruit-shaped swelling at the base. Bees carry pollen from male to female flowers. If few bees come, gardeners use a small paintbrush to move pollen. Without pollination, the little fruit shrivels and falls off.
