WHAT IS A PLANT?
Lif in water is pretty sweet why?
why is water important, why do plants need water?
Novel traits developed by plants: DESSICATION(c+s+s) & STRUCTURAL SUPPORT AND TRANSPORTING WATER
3 types non vascular plants byrophytes:
- thought to be closest living descendants ofn 1st land plants
- no vascular tissue
- no well developed roots
NV: Byrophytes: liverwort
NV:Byrophytes= HORNWORTS key points
MOSSES (NVB)
ALSO, mosses: sphagnum are known to have high tolerence of dessication. due to microphyll cells (PS and H)
- LYCOPHYTES in seedless vascular plants
- MONOLYPHYTES in SEEDLESS VASCULAR PLANTS
- MONOLYPHYTES: reproduction in SEEDLESS VASCULAR PLANTS
LINK SEED AND SEEDLESS PLANTS
FEATURES SHARED BY ALL SEED PLANTS: 1. all have seeds
FT SHARED BY ALL SED PLANTS : alternation of generation
GAMETOPHYTE REDUCTION, sporophyte INCREASE.
- G= contain gametes,they are precious
2, in seed plants GAMETOPHYTE= protected against UV and dessication and OBTAIN NUTRIENTS FROM PHOTOSYNTHETIC SPOROPHYTES
FT SHARED BY ALL SEED PLANTS. 3. HETEROSPORY
V
GYMNOSPERM- SEED PLANTS, NO FLOWER REPRODUCTION
4 main types of gymnosperm
3 key innovations in angio sperms
- AS: FLOWERS= EFFICEINT TRANSPORT OF POLLEN
- PRODUCTION OF SPERM AND EGG IN ANGIOSPERM
- AFTER POLLINATION (AS)
characteristics of monocot and eudicot , MAJOR GROUPS OF ANGIOSPERM
MONO OR EUDICOT?
3 TYPES OF TISSUE
1st TISSUE TYPE: dermal= epidermis
2nd type tissue GROUND!
LABEL GROUND TISSUE TYPE!!
PS&G: INDETERMINATE GROWTH how is it achieved?
Lateral Meristem
casparian strip
SHOOTS OF PLANT: monocot stem
