Tiny pores present on the leaves of plants are called as:
A. Stomata
B. Cells
C. Chlorophylls
D. Grains
Tiny pores present on the leaves of plants are called as:
A. Stomata
B. Cells
C. Chlorophylls
D. Grains
The correct option is: A
Explanation of the correct option:Leaves have tiny pores called stomata which help in the gaseous exchange.
The exchange of oxygen, and carbon dioxide through stomata
They are majorly present on the underside of the leaves.
Stomata is responsible for transpiration (loss of water vapor occurs).
Explanation of the incorrect option:
Option B: The smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
A cell has three main parts:
1. cytoplasm
2. cell membrane
3. nucleus.
Option C: Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy. The chlorophyll pigment is responsible for the green colouration in plants.
Option D: A grain is a small, hard, dry seed – with or without an attached hull or fruit layer – harvested for human or animal consumption. A grain crop is a grain-producing plant.
