A
Carotenoids
B
Chlorophyll b
C
Phycobilins
D
Chlorophyll a
Verified step by step guidance1
Understand the role of chlorophyll in photosynthesis: Chlorophyll is a pigment that plays a crucial role in the process of photosynthesis by absorbing light energy, which is then converted into chemical energy.
Identify the types of chlorophyll: There are several types of chlorophyll, including chlorophyll a, chlorophyll b, and others. Each type absorbs light at different wavelengths.
Recognize the primary pigment: Chlorophyll a is the primary pigment used in photosynthesis by both plants and cyanobacteria. It is essential for the conversion of light energy into chemical energy.
Differentiate between accessory pigments: Carotenoids and phycobilins are accessory pigments. They assist in photosynthesis by capturing additional light energy and passing it to chlorophyll a, but they are not the primary pigments.
Conclude with the correct molecule: Based on the roles and functions of these pigments, chlorophyll a is the molecule used in photosynthesis by both plants and cyanobacteria.
