Asexual reproduction : 1. Cell division is itself a mode of reproduction in Protists and Monerans. 2. Many single-celled organisms reproduce by binary fission, where a cell divides into two halves and each rapidly grows into an adult (e.g., Amoeba, Paramecium). 3. In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which, eventually gets separated and mature into new yeast organisms. Regarding 1, 2 and 3 :


( A ) 1 is correct; 2 and 3 are incorrect
( B ) 1 is incorrect but 2 and 3 are correct
( C ) All are correct
( D ) 2 is incorrect but 1 and 3 are correct
Can you answer this question?

(C) is the right answer.

In Protists and Monerans, the organism or the parent cell divides into two to give rise to new individuals. Thus, in these organisms cell division is itself a mode of reproduction. Many single-celled organisms reproduce by binary fission, where a cell divides into two halves and each rapidly grows into an adult (e.g., Amoeba, Paramecium). In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which, eventually gets separated and mature into new yeast organisms (cells).
