Biology Revision Notes - Five Kingdoms:
Five Kingdoms:
o Fungi
o Plantae
o Animalia
o Protoctista
o Prokaryotae
Prokaryotae:
o Organisms which do not have a membrane bound nucleus
o MOST reproduce via BINARY FISSION ­ cells grow, DNA
replicates and cell divides into two
Fungi:
o All are HETEROTROPHIC ­ complex organic molecules are
broken down to simpler ones
o Cell walls are made of ­ CHITIN
o Store CARBOHYDRATE in the form of ­ GLYCOGEN
o Show LITTLE TISSUE DIFFERENTIATION which means there are
no distinct organs
o EXTRACELLULAR DIGESTION ­ HYPHAE
Plantae:
o All are AUTOTROPHIC ­ simple inorganic molecules are used to
make more complex organic molecules
o Sub-divided into two main groups:
NON-FLOWERING e.g. MOSSES and ferns
FLOWERING e.g. trees, grasses, blue bells
o Cell walls are made of ­ CELLULOSE
o Show TISSUE DIFFERENTIATION into roots, stem and leaves
o Contain CHLOROPHYLL
o Store CARBOHYDRATE in the form of STARCH
Animalia:
o All are HETEROTROPHIC ­ complex organic molecules are
broken down to simpler ones
o Multicellular, don't have CELL WALLS
o Contain specialised cells and tissues e.g. NERVOUS and MUSCLE
TISSUES
o TISSUE ­ collection of similar cells with a common function
o Store CARBOHYDRATE in the form of ­ GLYCOGEN
