Question

How does plant obtain raw materials for making food

Answer 1

plant obtain raw materials like water from the soil and air from the atmosphere.

Answer 2

Essential raw materials for photosynthesis are -

carbon dioxide: it is a gas which is released into atmosphere during respiration.

Water: it is another requirement for photosynthesis which is transported upward through xylem tissue to the leaves, from where it reaches photosynthetic cells.

Chlorophyll: it is green pigment in plants which act as catalyst. It is responsible for absorption of sun's light by the plant. The chlorophyll pigments are photoreceptor molecules which play a key role in the photosynthesis process.

Light: light effects photosynthesis with its intensity, duration and quality. In green light the rate of photosynthesis is minimum, while in red or blue light the rate of photosynthesis is maximum.
