Plant Kingdom Flashcards
1
Q
Explain the plant life cycle for the alternation of generations
A
Sporophyte (2n/diploid generation) undergoes meiosis to make spores (n). Germination takes place to make a gametophyte (n/haploid generation). The gametophyte undergoes mitosis to make a sperm and ova which fertilise each other to make another sporophyte (2n/diploid generation)
2
Q
What is the dominant generation for mosses?
A
Gametophyte generation (haploid)
3
Q
Do mosses have a vascular system?
A
No
4
Q
What do mosses need to reproduce and what do they produce?
A
Need water to reproduce and produce sperm
5
Q
What is the dominant generation in ferns?

Sporophyte generation (diploid)
6
Q
Do ferns have true leaves?

Yes
7
Q
Are ferns homosporous or heterosporous?
