Question

Which of the following cell organelles constitute the protoplasm?
A) cell membrane
B) cytoplasm
C) nucleus
D) both B and C

Answer 1

Hint: The cell is the basic unit of life. In a cell, there is the presence of various cell organelles that help in the working and functioning of the cell. The cell membrane is the outer covering of the cell which helps in giving the shape to the cell.

Complete answer:
 The main living part of the cell which is surrounded by the plasma membrane is known as the protoplasm of the cell. The protoplasm consists of the genetic material of the cell. It plays an important role in controlling the functionality of the cell. the nucleus constitutes the protoplasm of the cell. It was first discovered by Robert Brown. The nucleus is the main center where the hereditary activity of the cell takes place. The nucleus is surrounded by the double-layered membrane namely, the outer layer and the inner layer nuclear membrane. The nuclear membrane has pores present on it known as the nuclear pore. There is the presence of nucleoplasm inside the nucleus. The genetic material is present inside the nucleus and it controls all the activity of the cell to carry out the hereditary information. This information is passed on from one generation to the next generation.
So, the answer is option (C) ‘nucleus’.

Note: The protoplasm is the living component of the cell. it is surrounded by the plasma membrane. The protoplasm is divided into parts which are the nucleoplasm and the cytoplasm. The cell organelles which constitute the protoplasm are chloroplast, mitochondria, Golgi apparatus, nucleus, and endoplasmic reticulum. The function of the protoplasm is to control the activity of the cell and help in its proper functioning.
