Question

Green pigment is found
(a)In roots
(b)In leaves
(c)In stem
(d)All of the above

Answer 1

The primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll and a number of other colorful pigments that absorb the maximum amount of light energy as possible.

Complete answer:
Green pigment is also known as Chlorophyll, which is the primary pigment in plants. Green pigments are found in leaves. Which is important in photosynthesis, allowing plants to soak up energy from light. It is the presence and relative abundance of chlorophyll that provides plants their green color.

Additional Information:
-Chlorophyll consists of small coin-shaped structures known as thylakoid which are stacked on top of each other and collectively known as grana. These are joined by stroma lamellae. The ground substance of Chloroplast is known as the stroma.
-Chlorophylls absorb sunlight most vigorously in the blue part of the electromagnetic spectrum as well as the red part.
-Contrary, it is a poor absorber of the green and near-green part of the spectrum, which it reflects, producing the green color of chlorophyll-containing tissues.
-There are two types of chlorophyll present in the photosystems of green plants that are chlorophyll a and b.
-Chlorophyll is a green photosynthetic pigment, they are present in mostly plants, algae, and cyanobacteria.
-Its giant molecule is made up of carbon, hydrogen, oxygen, nitrogen & magnesium.
So, the right answer is ‘All of the above’.

Note:
-Lutein is a yellow pigment present in vegetables and fruits. It is the richest carotenoid in plants.
-Lycopene is the red pigment liable for the color of tomatoes.
