An Overview

The leaves are eco-friendly in colour mainly because of the green colour pigments existing within the plant cell called the chlorophyll. This colors is provided by every vascular tree to transform light energy into chemical energy via photosynthesis.

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

Chlorophyll pigments are likewise involved in the photosynthesis process by absorbing sunlight required for the manufacturing of carbohydrates in the plants. The is uncovered in the thylakoid membranes in the chloroplastic – the environment-friendly coloured plastids existing in the plant cells.

There are different species of Chlorophyll, amongst which the Chlorophyll A and Chlorophyll B play a far-ranging role in the biological procedure of photosynthesis.

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