Q
Novel traits developed by plants: DESSICATION(c+s+s) & STRUCTURAL SUPPORT AND TRANSPORTING WATER
A

23
Q
3 types non vascular plants byrophytes:
A
- thought to be closest living descendants ofn 1st land plants
- no vascular tissue
- no well developed roots

24
Q
NV: Byrophytes: liverwort

A

25
NV:Byrophytes= HORNWORTS key points


26
MOSSES (NVB)
ALSO, mosses: sphagnum are known to have high tolerence of dessication. due to microphyll cells (PS and H)

27
1. LYCOPHYTES in seedless vascular plants


28
1. MONOLYPHYTES in SEEDLESS VASCULAR PLANTS

29
1. MONOLYPHYTES: reproduction in SEEDLESS VASCULAR PLANTS

30
LINK SEED AND SEEDLESS PLANTS


31
FEATURES SHARED BY ALL SEED PLANTS: 1. all have seeds


32
FT SHARED BY ALL SED PLANTS : alternation of generation

GAMETOPHYTE REDUCTION, sporophyte INCREASE.
1. G= contain gametes,they are precious
2, in seed plants GAMETOPHYTE= protected against UV and dessication and OBTAIN NUTRIENTS FROM PHOTOSYNTHETIC SPOROPHYTES

33
FT SHARED BY ALL SEED PLANTS. 3. HETEROSPORY
