• D. d-iv-4

Answer 1

Answer: (A), (B), (D)

The correct options are
A a-i-1
B b-ii-2
D d-iv-4

• Exchange of gases takes place through leaves, lenticels and some loose tissue in plants. Carbon dioxide is taken inside cells and oxygen is released in the air.
• Chloroplast is the cell organelle which contains chlorophll. Sunlight, chlorophyll, water and carbon dioxide are the raw materials for photosynthesis. During this process, glucose is produced as an energy source.
• The transpiration process takes place in the leaves of the plants. In this process, the excess amount of water is lost in the form of vapour.
• Roots absorb water and nutrients from the soil through the process of diffusion. It involves movement of substances from high concentration to low concentration.
