Question 7

What is the main evolutionary advantage of seeds over spores?

Accepted Answer

Seeds are multicellular, have a protective coat, and contain a food supply

Question 8

Which of the following statements about gymnosperms is correct?

Accepted Answer

They produce seeds that are not enclosed in an ovary

Question 9

Which of the following is a defining feature of angiosperms?

Accepted Answer

Production of seeds within a mature ovary (fruit)

Question 10

A botanist discovers a plant with parallel leaf veins, flower parts in multiples of three, and a single cotyledon in its seed. To which group does this plant most likely belong?

Accepted Answer

Monocots

Question 11

Which of the following best describes the process of double fertilization in angiosperms?
