Answer the following questions:

Diagrams of two different cells are given below. Which one of the two is a plant cell? Support your answer.

(i) Name the parts 1, 2, 3 and 4.

(ii) Write the functions of 1 and 3.

(iii) Draw a diagram to show the structure of 4 and label the parts.

(iv) Draw a diagram of a plant cell and label the parts.

The diagram on the right depicts a plant cell as it possesses a cell wall. The nucleus is also peripheral.

(i) Part 1 – Endoplasmic reticulum

Part 2 – centriole

Part 3 – vacuole

Part 4 – chloroplast

(ii) The function of ER:

Endoplasmic reticulum forms a network of tube-like structures near the nucleus. It is responsible for folding of protein molecules and transporting various synthesized molecules (protein and carbohydrate) to the Golgi body and lysosome.

The function of vacuole:

Vacuole serves as a storage organelle. It is usually the largest organelle in a plant cell. It stores various food particles, excess water, and waste products. In addition, it also maintains pressure within the cell and provides structural support to the cell.

(iii) Diagram of chloroplast:

(iv) Plant cell
