NEET BIOLOGY

Detailed explanation-1: -In unicellular organisms such as bacteria, mitosis helps in asexual reproduction as it produces an identical copy of the parent cell. Another example of the Eukaryotic unicellular organism is “Amoeba.” An amoeba uses cell division for the production of new individuals.

Detailed explanation-2: -All eukaryotic organisms-including aquatic plants and algae-grow through the process of mitosis. Mitosis is a process where one cell divides into two cells (Fig.

Detailed explanation-3: -Both unicellular and multicellular organisms undergo mitosis.

Detailed explanation-4: -Strictly speaking, the only type of reproduction in Paramecium is asexual binary fission in which a fully grown organism divides into two daughter cells. Paramecium also exhibits several types of sexual processes. Conjugation consists of the temporary union of two organisms and the exchange of micronuclear elements.

Detailed explanation-5: -Paramecium is a unicellular organism that swims in fresh water by beating thousands of cilia.
