Chapter 6: Problem 20

The green pigment that traps solar energy during photosynthesis is (a) Anthocyanin (b) Carotenoid (c) Haemoglobin (d) Chlorophyll

Short Answer

Expert verified
Answer: (d) Chlorophyll

Step by step solution

01

Analyzing Option A - Anthocyanin

Anthocyanins are a group of pigments responsible for the red, blue, and purple colors in plants, fruits, and flowers. They do not play a role in photosynthesis; hence, this option is not correct.
02

Analyzing Option B - Carotenoid

Carotenoids are a group of pigments responsible for the yellow, orange, and red colors in plants, fruits, and vegetables. They help in photosynthesis by acting as accessory pigments and protecting the plant from excess light, but they are not the primary pigment that traps solar energy. Therefore, this option is not correct.
03

Analyzing Option C - Haemoglobin

Haemoglobin is a protein found in red blood cells of animals, responsible for carrying oxygen throughout the body. It is not involved in photosynthesis and not found in plants. This option is not correct.
04

Analyzing Option D - Chlorophyll

Chlorophyll is the green pigment present in plants, algae, and some bacteria. It is responsible for absorbing light energy from the sun and converting it into chemical energy during photosynthesis. This pigment gives plants their green color, and it is the primary pigment responsible for trapping solar energy.
05

Answering the question

Based on the analysis of each option, the correct answer is: (d) Chlorophyll, as it is the green pigment that traps solar energy during photosynthesis.
