Prepare a model of any microorganism. And write a note on them.

A model of amoeba as shown below can be prepared.

Amoeba is a single cell microscopic organism which is found in water bodies.

It always keeps on changing its shape with the help of the pseudopodia. (Pseudo-false and podia-feet) i.e. amoeba have this false feet which help it to continuously change its shape and capture its food.

Being unicellular all functions of amoeba are performed by a single cell.

It consists of the following parts:

● Cell membrane: Cell of amoeba is lined by a thin layer which allows passing of materials through it selectively.

● Pseudopodia: As told above pseudopodia are false feet present in amoeba. These are kind of outgrowths which help it to move, change its shape and capture its food. With the help of pseudopodia it takes its food.

● Cytoplasm: This is the liquid substance present within the cell. It is also responsible for the formation of pseudopodia. The cytoplasm contains nucleus and vacuoles inside it.

● Nucleus: It controls all activities of amoeba. It is also surrounded by a membrane.

● Contractile vacuole: It regulates the quantity of water present in cell.

● Food vacuole: It stores the food taken by amoeba.

Amoeba is also able to cause diseases. It causes disease like amoebiasis.
