Question

Where is chlorophyll mainly present in the plant?

Answer 1

Hint: The primary pigment utilised in photosynthesis is referred to as chlorophyll. It reflects green light and absorbs the light of red and blue wavelength most strongly.

Complete answer:
All plants, algae and cyanobacteria possess chlorophyll, which is a green pigment in leaves and stems. It is a pigment that absorbs light, and it actually gets its green colour because it absorbs light of blue and red wavelengths. Since it is a light-absorbing pigment, chlorophyll is known as a photoreceptor.

In plants, the process of photosynthesis occurs in chloroplasts containing chlorophyll. Chloroplasts are double membrane-bound organelles and also contain a third inner membrane, known as the thylakoid membrane, that forms long folds inside the organelle.

The green pigment chlorophyll is mainly present within the thylakoid membrane, and the space present between the chloroplast membranes and the thylakoid is known as the stroma. The primary role of chloroplasts is to carry out the process of photosynthesis, consisting of many reactions such as Light reaction and carbon assimilation reaction. Hence we can conclude that the entire process of photosynthesis occurs in chloroplasts, whereas the role of chlorophyll is to reflect green colour and absorbs blue and red wavelength.

Note: There are many kinds of chlorophyll and numerous other pigments that respond to light but Chlorophyll A is the major pigment that is utilised in photosynthesis. Chlorophyll, like that of mitochondria, is also known as the ‘powerhouse‘ of the cell, as it is also responsible for the synthesis of ATP and other reactions.
