Fill in the blanks with the appropriate raw materials.

(a) Available in the plant : _______________.

(b) Available in the soil : _______________, _______________.

(c) Available in the air : _______________.

(d) Available during day : _______________.

Answer 1

Photosynthesis:

1. Photosynthesis is the process of synthesizing organic compounds using sunlight, water, and carbon dioxide.
2. It helps to convert light energy into chemical energy.

Raw ingredients used in photosynthesis:

1. Carbon dioxide: It is take-up by the stomata, which is a gaseous exchange system.
2. Water: Roots absorb water from the soil.
3. Solar energy is trapped by chlorophyll, a green pigment found in green plants.

Final answer:

(a) Available in the plant: chlorophyll.

(b) Available in the soil: water and minerals.

(c) Available in the air: carbon dioxide.

(d) Available during day: sunlight.
