Phylogentic Tree
2
Q
what is the common ancestor of all pants
A
aquatic algae ancestor
3
Q

A
48-0 million years ago
4
Q
what are the four developmental directions to adapt to terrestrial life?
A
- develop cuticle
- vascular tissue (xylem and phloem for transport of water and nutrients)
- seeds
- flowers
5
Q
what is the difference between vascular and non-vascular tissue?
A
- vascular tissue: contains xylem and phloem
- non-vascular tissue: doe not contain xylem and phloem
6
Q
4 divisions of plantae
A
- Bryophytes
- Pteriodoophytes
- Spermatophytes
- Gymnospermae
- Angiospermae
7
Q
what does alternation of generation mean?
A
when a asexual generation and a sexual generation alternate with each other
8
Q
what is asexual generation called
A
gametophyte generation
9
Q
what is the sexual generation called
A
gametophyte generation
10
Q
what is the difference between haploid and diploid
A
Haploid:
- half amount of chromosomes
- produce by meiosis
- 23 in humans
- gametophyte generation
Diploid:
- full amount of chromosomes
- produce through fertilization
- 46 in humans
- sporophyte gen
