NEET BIOLOGY

Detailed explanation-1: -The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

Detailed explanation-2: -The food-making process takes place in millions of leaf cells which contain a pigment known as chlorophyll. Chlorophyll is green and there is so much of it in a grown leaf that it gives the leaf its green color.

Detailed explanation-3: -Chlorophyll allow plants to absorb energy from light. Chlorophyll is responsible for the green color of many plants and algae. Seen through a microscope, chlorophyll is concentrated within organisms in structures called chloroplasts – shown here grouped inside plant cells.

Detailed explanation-4: -Now later when the proto-cyano and cyanobacteria came along, they evolved chloroplasts that used the wavelengths left over (mainly blue then red) so as to not compete with the majority. Therefore they absorb blue and red and reflect green, hence are green.

Detailed explanation-5: -As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
