Q2. Who discovered the cell?
Robert Hooke discovered cells in 1655. He came across this while exploring and examining a cork which is a part of the bark of a tree. Hook observed thin slices of cork under a microscope that he designed himself. Under that, he observed that there were several tiny compartments and partitioned boxes just like a honeycomb. Upon further notice, he could see that each compartment and box are divided from each other by a wall. He later termed all the single compartments and boxes as "cells".
Q3. What are the basics of Chapter 8 Cell Structure and Functions of Class 8 Science?

It then moves on to the structure of the cell and its characteristics. This chapter even focuses on the different types of cells and the different number of cells available in the animal and human body as well as in plants. Therefore, it is important to understand this chapter as it will help Students create a fundamental base for similar chapters.
Q4. What are cells?
Cells are generally considered to be the basic unit of life as they are the building blocks of all living matter. It contains many molecules and chemicals. There are two types of cells found. These include multicellular and unicellular organisms. Both these cells have their own unique characteristics and functions. A cell has three main parts namely the nucleus, the cell membrane, and the cytoplasm. Although all living organisms are made up of cells, one cell can differ from another.
Q5. What is the difference between a plant cell and an animal cell?
The main difference between a plant cell and an animal cell is that in an animal cell the cell wall is absent, whereas a plant cell has a rigid cell wall. A plant cell comprises chloroplasts while animal cells don’t have chloroplasts in them. Since an animal cell does not have a cell wall, it comprises a Centrosome that is present near the nucleus. A centrosome refers to a cell organelle which divides the cells. The Centrosome in a plant cell is absent.
