Question

The growth of cells is regulated by
A. Nucleus
B. Mitochondria
C. Vacuole
D. Golgi complex

Answer 1

Hint:-Cell growth can be in terms of an increase in cell mass or cell number. Division of cells leads to an increase in cell number (proliferation) while enlargement of cells leads to an increase in cell mass. These events are primarily dictated by the expressions of genes that initiate biosynthesis of specific biomolecules.

Complete Answer:-Every organelle inside the cell has its unique function and mode of action and together, they orchestrate and ensure successful operation of the cell. Since they are embedded in the viscous cytoplasm, the whole setup can be seen to be much like a factory with small compartments/ rooms assigned for specific functions.

Among the given options, Nucleus is the storehouse of the cell’s genetic material which has to properly read and utilised for the smooth carrying out of the cellular activities, metabolism and growth, Mitochondria are famously known for being the powerhouse of the cell meaning that they provide the cell with energy in the form of ATP, the fluid-filled Vacuoles store the food and nutrients until necessary and the Golgi complex regulate the process of packaging, transporting and shipping of proteins and lipids to assigned destinations.


Thus, the correct answer is (A), Nucleus.

Note:- Cell growth is the key to survival in all organisms – for unicellular organisms, cell growth is the mode of reproduction while in multicellular organisms, it results in tissue growth and organ generation. Improper cell regulation can lead to catastrophic damage to the genes which can lead to cancer or death.
