Question

Why is nucleus referred to as the controller of cellular activities?

Answer 1

The nucleus is referred to as the controller of cellular activities because:

1. The nucleus is the storehouse of genes (genetic information) that are concerned with the development and manifestation of all the body characters.
2. The nucleus contains thread-like structures called chromosomes. These carry genes and help in the inheritance or transfer of characters from the parents to the offspring.
3. The genetic material of the nucleus determines the formation of enzymes and proteins in ribosomes.
4. The nucleus decides when and how these enzymes are to be formed.
5. Enzymes in turn control cellular activity.
6. Hence, the nucleus is referred to as the controller of cellular activities.
