Practical 01:

Euglena is single celled organisms that belong to the protist. As such, they are not plants, animal or fungi. In particular, they share some characteristics of both plants and animals. While they can manufacture their own food, a characteristic seen in plants, they are also capable of movement and also consume food, which are characteristics of animals. Move by false feet called pseudopodia

Can change shape

Structure of amoeba primarily encompasses 3 parts – the cytoplasm, plasma membrane and the nucleus.

The cytoplasm can be differentiated into 2 layers – the outer ectoplasm and the inner endoplasm

The plasma membrane is a very thin, double-layered membrane composed of protein and lipid molecules.

Amoeba also contains other cellular organelles such as a contractile vacuole, mitochondria, Golgi apparatus and fat globules.

Amoeba consumes food either through the process of phagocytosis or pinocytosis.

The process of reproduction is through asexual means, such as binary fission.

Practical 03:

Entamoeba cells are small, with a single nucleus and typically a single lobose
