Amoeba

Explanation:

• Amoeba is an example of Protozoa.
• It is a unicellular organism that can change its shape, it is usually found inside water bodies and can also cause diseases in Humans.
• Amoeba moves with the help of pseudopodia.
• The cytoplasm pushes the plasma membrane outwards or inward creating a finger-like projection.
• Pseudopodia can be multiple in numbers.
• It generally consists of three parts the cytoplasm, plasma membrane, and nucleus.
• The cytoplasm is differentiated into 2 layers, the outer is called ectoplasm, and the inner endoplasm.
• It contains organelles such as vacuole, mitochondria, Golgi apparatus and fat globules.
• Phagocytosis is seen in amoeba for food consumption.
