Question

Amoeba is a ___________ celled organism. It reproduces by ___________ reproduction. The process of reproduction begins by the division of its ___________ into two. This is followed by the division of its ___________ into two. This type of reproduction is called ___________ fission. Fill up the blanks with the terms: (body. asexual, binary, single, nucleus)

Answer 1

Amoeba:

1. Amoeba is a unicellular primitive organism possessing the ability to change shape and form.
2. Amoeba moves via the use of blunt finger-like projections known as pseudopodia, where the cytoplasm pushes the plasma membrane outward or inward.
3. Amoeba's shape changes rapidly as the pseudopodia can be present at multiple locations at a particular instance.
4. The structure of amoeba primarily encompasses 3 parts – the cytoplasm, plasma membrane, and nucleus.
5. The amoeba cytoplasm is differentiated into 2 layers, the outer ectoplasm, and the inner endoplasm.

Final answer: Amoeba is a single-celled organism. It reproduces by asexual reproduction. The process of reproduction begins with the division of its nucleus into two. This is followed by the division of its body into two. This type of reproduction is called binary fission.
