Question

Write a brief note on cell structure of amoeba with a neat labelled diagram.

Answer 1

Amoeba is a unicellular microscopic organism. It is found in ponds. Amoeba is irregular in shape.

• It has cell membrane, cytoplasm and nucleus. It is a protozoan that move by means of pseudopodia (in Latin, “false feet.”) Pseudopodia are the extended part of cell membrane. It helps to catch its prey (algae).
• The body ‘flows’ around the food particle and engulfs it forming food vacuoles. Contractile vacuoles are seen in the cytoplasm that help in excretion.
• Amoeba reproduces by means of binary fission.
