2a)What are unicellular organisms and how do they differ from multicelluar organisms in

terms of cell organisation? [2m]

b) Amoeba sp. is a unicelluar organism which can be found in freshwater ponds rich in

decaying organic matter.

Explain how freshwater Amoeba sp adapts to living freshwater environment. [4m]

c)Explain how Amoeba sp. reproduces in response to different conditions in

environment.

[4m]

d)Unicellular organisms do not require a transport system.

Using Amoeba sp as example, give an evaluation of the above statement based on the

physical features of a unicellular organism with respect to the following processes:

-Locomotion

-Nutrition

-Respiration
