Question

The process of photosynthesis takes place in
A. Roots only
B. Shoots only
C. All cells of the plant
D. Chlorophyll containing cells only

Answer 1

Hint: This compound is solely responsible for the green color of the leaves and is present embedded in the thylakoid membranes.

Complete answer:
The process of photosynthesis takes place in chlorophyll containing cells only.
The process by which all green plants and a few other autotrophic organisms convert light energy into chemical energy, which is later used as fuel for different cellular activities is known as photosynthesis. The process of photosynthesis takes place in the mesophyll of the leaves, inside chloroplasts through photosynthetic pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll. The by-product of the photosynthesis process is oxygen and glyceraldehyde-3-phosphate (G3P). Chlorophyll captures energy from sunlight and absorbs some portion of visible spectra.

Additional Information: The underground, branched structures that firmly anchor the plant to a fixed spot are called roots. These serve as transport systems for water and dissolved nutrients from soil, allowing the plant to grow properly.
The shoot system aids a plant to reach greater heights to gain access to energy-giving light, and allows the plant to convert that light energy into the chemical energy of sugar.
So, the correct answer is ‘chlorophyll containing cells only’.

Note: - The chemical energy is stored in the form of sugars, by using water, sunlight, and carbon dioxide.
- Mesophyll is a layer of cells that comprises most of the interior of the leaf between the upper and lower layers of epidermis.
- The chlorophyll pigments maximally absorb red and blue lights.
