Classification
method used to organise living things into groups
Taxonomy
The feild of science responsible for identifying and classifying organisms
name
genus & species
given from the binomial system
Taxon

Protista
Unicellular, multicellular, animal like, plant like, or fungal like
Fungae
multicellular and nonmotile
Secrete enzymes to absorb nutrients

Recognition features of bryophyta, filicinophyta, coniferophyta and angiospermophyta
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
