Question 19

Recognition features of bryophyta, filicinophyta, coniferophyta and angiospermophyta

Answer 19

bryophyta:
- no vascularisation
- no ‘true’ leaves, roots or stems
- Reproduce by releasing spores from sporangia

filicinophyta:
- Has vascularisation
- Have leaves, roots and stems
- Reproduce by releasing spores

Coniferophyta:
- Has vascularisation
- Have leaves, roots and stems (stems are woody and leaves are waxy and needle-like)
- Reproduce by non-motile gametes (seeds)

Angiospermophyta:
- Has vascularisation
- Have leaves, roots and stems
- Reproduce by seeds produced in ovules within flowers
