Question

How do plants prepare their food? Explain the factors on which the process of photosynthesis depends?

Answer 1

Photosynthesis:

1. Plants make their food through the photosynthesis process.
2. Since the plants are autotrophs, they can make their food using inorganic substances like carbon dioxide and water through the process of photosynthesis.
3. In photosynthesis, plants make use of sunlight, water, and Carbon dioxide.
4. It creates oxygen and energy in the form of sugar as the byproduct.
5. It generally involves the green pigment chlorophyll to generate oxygen as a by-product.
6. Photosynthesis takes place in the chloroplast which is present in the leaves.

The factors on which the process of photosynthesis depends are:

1. Light Intensity: More the light intensity, higher rate of photosynthesis. Low light intensity, lower rate of photosynthesis.
2. The concentration of CO₂: Higher concentration of C0₂ increases the rate of photosynthesis.
3. Temperature: For photosynthesis, the temperature must be in the range of 25° to 35° C.
4. Water: The deficiency of water leads to the refusal of stomatal opening to retain the amount of water they have stored inside them.
5. Pollution: Industrial pollutants and other particulates may settle on the leaf surface and blocks the pores of stomata making it difficult to take in CO₂.
