Question

explain the binary fission in amoeba and regeneration in planaria ?​

Answer 1

binary fission....it is a type of asexual reproduction by which a single parent cell divides into two cell ... either through the plane passing through the centre or any other plane...

regeneration...it is also a type of a sexual reproduction in which the parts which are lost due to some conditions or damage are region narrated by some cells present at that parts

Answer 2

Answer:

Binary Fission in amoeba: Most single-celled organisms use the method of binary fission for cell division and reproduction. These include paramoecium, bacterium, and finally amoeba. In this paragraph, we will be focusing on amoeba’s cell division which is also its method of reproduction. In binary fission, the amoeba consists of one parent which forms the 2 daughter cells. First, the amoeba cell undergoes nuclear division and replicates into two nuclei. The two nuclei divide and move to opposite directions in the parent cell. The cell then produces proteins and nutrients in preparation for binary fission. In the stage of binary fission, the cell divides and forms 2 daughter cells. This process generally occurs when environmental conditions are most favorable. That is when there is enough food, water, and a favorable temperature.

Explanation:

Regeneration is defined as the process of growing a full organism from its body part. The examples of regeneration are: Hydra and Planaria. When the body of Planaria is cut into number of pieces, the each and every body piece can regenerate and results in formation of a complete Planaria. The regeneration of an organism occurs by the process of growth and development The cells of body part which has been cut down gets divides and makes a ball of cells. These multiple cells result in formation of tissues and forms organs again and results in regeneration of another Planaria.
