Identify the element that helps to trap light energy that is essential for photosynthesis.

Carotenoid

The correct answer is Option (3)- Carotenoid

Carotenoid is the element that helps to trap light energy that is essential for photosynthesis.

Explanation:

• Carotenoids are pigments found in the chloroplasts of plant cells.
• They play a crucial role in photosynthesis by absorbing light energy and transferring it to chlorophyll molecules, the primary pigments involved in capturing light for photosynthesis.
• Carotenoids contribute to the range of colors observed in plants, such as the orange color of carrots and the yellow color of corn.

So, the correct answer is Carotenoid.
