Examples include red kangaroo.
Dentition:
Prominent incisors for the initial cutting of vegetation. Lacks canine teeth but has large flat molars and premolars for the breakdown of the tough cellulose found in grass.
Digestive tract:
Long and complex. Has a caecum for the fermentation of cellulose by gut microorganisms.
Unicellular organisms such as bacteria are made up of one cell. The cell can carry out all the necessary functions in the organism.
Multicellular organisms such as animals and plants consist of many specialised cells that work together to perform different tasks in the body. The cells cannot survive on their own if separated.
Colonial organisms such as Pandorina refer to a colony of single-celled organisms living together. The cells in the colony can survive on their own if separated.
