A potato stores food underground. Which plant structure is it, according to the material?
- A
A storage root
- B
A storage stem
- C
A leaf modified for storage
- D
A seed

- A
Modified roots that absorb water
- B
Modified leaves that reduce water loss
- C

- A
True
- B
False

- A
Xylem carries water and minerals, mainly upward.
- B
Phloem carries water and minerals, mainly upward.
- C
Xylem's strengthened cells also support the plant.
- D
Phloem is the tissue that anchors the plant in soil.
Select all statements that correctly describe plant alternation of generations.
- A
A haploid gametophyte produces gametes.
- B
Fertilization forms a diploid zygote.
- C
The sporophyte produces haploid spores by meiosis.
- D
A spore is diploid and develops directly into a zygote.
- E
The gametophyte develops from the diploid zygote.
True or false: All major groups of land plants have vascular tissue.
