Answer 1

31:stomata 32:xylem 33:meristems

Answer 2

1. Stomata: The small openings that allows the movement of gases from the leaves to the outer environment and from the environment to the plant body is known as stomata.

They consists of mesophyll cells that builds the pressure inside the cell because of which the gaseous exchange takes place.

2. Xylem: The water and nutrients from the soil is conducted to the plant body for the production of food by the help of the process known as photosynthesis.

This process is important for the plants and other organisms in order to survive and get energy.

3. Meristems: This is the region of the plant that keeps on dividing. These cells give rise to various organs of the plant body.

This is found in the growth regions. These cells are found in the roots of the plants.
