An Overview

The leaves are green in colour largely because of the green colour pigments current within the plant cell referred to as the chlorophyll. This pigment is used by all vascular plants to transform light energy into chemical power by means of photosynthesis.

You are watching: Which of the following is a difference between chlorophyll a and chlorophyll b?

Chlorophyll pigments are additionally affiliated in the photosynthesis process by absorbing sunlight required for the manufacturing of carbohydrates in the plants. It is discovered in the thylakoid membranes in the chloroplasts – the green coloured plastids present in the plant cells.

Tbelow are various types of Chlorophyll, among which the Chlorophyll A and Chlorophyll B play a significant role in the biological process of photosynthesis.

Let’s learn about the differences in between chlorophyll a and also chlorophyll b
