Topic 4; plant biology

Front

Division of labour

Back

cells are specialized to carry out certain functions efficently

Front

multicellularity size

Back

organisms can get larger when many cells work together for export efficiency of materials

Front

interdependence

Back

if one cell dies/damaged, the organsim is unaffected

Front

advantages of multicellularity

Back

-division of labour

-size

-interdependence

Front

the shoot system

Back

-stem, leaves, buds, flowers and fruits

-absorbs CO2 and release O2

-photosynthesis

Front

the root system

Back

Front

cellular adaptations

Back

Plants contain specialized clusters of meristems, where mitosis occurs only there. Plants only grow where the meristems cus mitosis only occurs on meristems.

Front

tissue adaptation types

Back

-Dermal

-ground

-vascular

Front

Dermal tissue

Back

-it is the outside layer on non-woody plants

-1 cell-layer thick

-responsible for gas exchange and protects from disease

-lenticels; are pores in wood

-cuticle; are wax coating to prevent water loss

-responsible for uptake of water and minerals from soil

Front

ground tissue

Back

-the majority of the middle, beneath the epidermis

-provides strentgh and support

-food and water storage in roots

-holds photosynthesis
