Lesson 2 - Cell

1. Tick the (√) true and cross (×) the false statements.

a. All the cells do not have similar shape.

b. Animal cells have cell wall.

c. Vacuole is big and permanent in plant cell.

d. Nucleus controls the activities of a cell

Answer 👉 

a. × (Most cells have similar shape, although there are some exceptions such as nerve cells and muscle cells.)

b. × (Animal cells do not have cell walls, but they do have a cell membrane.)

c. √ (Vacuole is usually large and permanent in plant cells.)

d. √ (The nucleus is the control center of a cell.)

2. Match the following.

Answer 👉 

a. Vacuole (empty space)

b. Chlorophyll (green colour pigment)

c. Nucleus (controls the cell activities)

d. Cytoplasm (flexible jelly)

e. Cell membrane (controls the cell activities)

3. Answer the following questions.

a. What is the smallest unit of body of living things?

Answer 👉  The smallest unit of the body of living things is a cell.

b. What is cell wall? Where is it found?

 Answer 👉 Cell wall is a rigid layer that provides structural support to the cell. It is found in plant cells and lies outside of the cell membrane.

c. What is cytoplasm? What does it contain?

Answer 👉 Cytoplasm is a jelly-like substance that fills the cell and contains various organelles such as mitochondria and ribosomes, as well as nutrients and other substances needed for cell function.

d. Where does nucleus lie? Why is it important?

Answer 👉 The nucleus lies in the center of an animal cell and on the edge of a plant cell. It is important because it contains genetic material (DNA) and controls the activities of the cell, such as growth and reproduction.

e. Write any two differences between plant and animal cell.

Answer 👉Two differences between plant and animal cells are:

  1. Plant cells have a cell wall made of cellulose, while animal cells do not.
  2. Plant cells have larger vacuoles than animal cells, which are involved in storing water and other substances. Animal cells have smaller vacuoles or none at all.
