S/A Lecture Notes Flashcards




EUKARYA SAR Clade: ALVEOLATES. LOCATE SACS


EUKARYA: SG2=SARCLADE (Alveolates: dinoflagellate,plasmodium, CILIATES)


EUKARYA:SG2 SAR CLADE= Aveolates(d+plasmodio+C) &STRAMENOPILES


EUKARYA: SG2 SARCLADE= Aveolates(d+plasmodium+C) & Stramenopiles( BA +Diatoms)




SG3:ARACHEPLASTIDA, RED, Green Algae




major group 4 in EUKARYA

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
