Explanation:
a)Binary Fission:
- Parent cell divides to give rise to 2 daughter cells
- No part of parent cell is left unused
- eg amoeba , Euglena
Multiple Fission:
- Parent cell divides into .multiple daughter cells
- The residual cell coverings and some cytoplasm are left unused
- eg:Plasmodium,Amoeba(encysted)
b) The chromosome number in the vegetative parts of the scion will be same as the original i.e. 30. However, in gamates; egg cell or pollen the chromosome number will be half of the original plant (in this case scion) so, it will be 15.I hope yeh tumhare madad karenge
