Vascular plants - Gymnosperes

Question 1

What two reproductive structures do gymnosperms produce to protect the sperm?

Answer 1

Gymnosperms protect their sperm through pollen (which carries the sperm to the female cone) and seeds (which protect the fertilized embryo).

Question 2

A tree produces a seed at the end of the growing season, right before the temperatures get too low for plant growth. Why is producing a seed an advantage in this situation?

Answer 2

Question 3

What is an advantage for a tree to retain its leaves all year, even in the cold season?

Answer 3
