Accepted Answer

Multicellularity → Invasion of land → Vascular tissue → Seed plants → Flowers

Question 3

Which of the following is NOT an advantage of seeds over spores?

Accepted Answer

Seeds are single cells and disperse less far than spores

Question 4

$$2n$$ embryo, $$n$$ food reserves, $$2n$$ maternal seed coat

Question 7

Which structure in angiosperms is responsible for attracting pollinators?

Accepted Answer

Petals

Question 8

What is the function of the endosperm in angiosperm seeds?

Accepted Answer

It is the food supply for the developing embryo

Question 9

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

Accepted Answer
