Question 2 - Past Year - 5 Mark Questions - Chapter 8 Class 10 - How do Organisms Reproduce?

(i) Describe the various steps involved in the process of binary fission with the help of a diagram.

(ii) Why do multicellular organisms use complex way of reproduction?

Answer:

(i)  The various steps involved in the process of binary fission are:

• DNA duplication and nucleus division
• Cytoplasm division which leads to cell division
• Two new daughter cells are formed.

(ii) Multicellular organisms are not a random collection of cells . 

In them, cells are organised into tissues which are further organised into organs . 

So, simple cell by cell division is impractical and hence, they use complex ways of reproduction.
