Certain specialised cells in animals called stem cells have the ability to divide and differentiate into different cell types.

Question

(a) Certain specialised cells in animals called stem cells have the ability to divide and differentiate into different cell types. This helps in the replacement of a damaged organ.

Name and explain two methods of asexual reproduction that are similar to stem cells and occur mostly in multicellular organisms.

(b) Identify TWO pairs of reproductive organs in males and females that are functionally similar to each other. Justify.

Answer 1

(a) Two methods of asexual reproduction that are similar to stem cells and occur mostly in multicellular organisms are 

Regeneration - In this process, if an individual organism is cut or broken up into many pieces, many of these pieces grow into separate individuals. - 

Budding - In budding, a small outgrowth or bud forms on the parent organism, which eventually detaches and develops into a new individual. 

(b) testes and ovaries 

Both structures perform the function of producing gametes and hormones crucial for reproduction

Vas deferens and fallopian tube 

Both structures are responsible for carrying the gamete to the site of fertilisation.
