Plant and Animal phyla 🌱🐰 Flashcards
1
Q
Angiospermophytes
A
- Vascularisation
- Flowering –> reproduce from seeds from ovules in flowers
- Roots, stems, leaves
- Eg: - all flowering plants and grasses `
2
Q
Filicinophytes
A
- Leaves, roots and stems (leaves are fronds that branch into leaflets)
- Reproduce via spores
- Vascularisation
- Eg:- Ferns
3
Q
Bryophytes
A
- No vascularisation
- Reproduce by spores
- Have rhizoid structures for roots –> no actual root, leaf, stem
- eg:- mosses, liverworts
4
Q
Coniferophytes
A
- Vascularisation
- waxy, needle-like leaves (leaves roots and stems –> stem woody)
- Reproduce via non-motile seeds
- Pine trees
5
Q
Cnidaria
A
- Mouth but no anus
- Radial symmetry
- May have tentacles with stinging cells –> capturing prey
- eg- jellyfish
6
Q
Porifera
A
- no symmetry
- no mouth or anus (exchange materials through pores)
- may have calcium carbonate spicules for support
- Eg - sea sponges
7
Q
annelida
A
- bilateral symmetry
- made of ring segments, w specialisation of segments
- mouth and anus separate
- eg - earthworm
8
Q
Platyhelmintha (think - the ‘plate-like’ bestie)
A
- Bilateral symmetry
- often flattened to increase SA:V ratio
- mouth but no anus
- eg - tapeworm and planaria
9
Q
Chordata
A
- Bilateral symmetry
- separate mouth and anus
- often have notochord + hollow, spinal nerve tube for some portion of life span
- eg human
10
Q
Arthropoda
A
- jointed body segments, w/ hard exoskeleton made of chitin
- bilateral symmetry
- separate mouth and anus
- eg - insects, spooders, crsuatceans, etc.
11
Q
Mollusca
A
- Body composed of a visceral mass, w a muscular foot and mantle
- mouth and anus
- bilateral symmetry
- eg - snail, clams
