Question

1.a. What is the major role of accessory pigments in photosynthesis.

b. Give 2 examples for accessory pigments. ​

Answer 1

Answer:

1)a) Role of Accessory Pigments: Accessory pigments help plants absorb additional light. Plants need to make these accessory pigments to maximize the amount of photosynthesis they can do. More pigments = More glucose or food for the plant!

b) Examples of accessory pigments are carotenoids (e.g. xanthophylls and carotenes) and phycobilins (e.g. phycoerythrin, phycocyanin, allophycocyanin, etc.).

Answer 2

Answer:

Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjunction with chlorophyll a. ... Some of these accessory pigments, in particular the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants.

Accessory pigments such as: cholorphyll b, carotenoids, xanthophylls and anthocyanins lend a hand to chlorophyll a molecules by absorbing a broader spectrum of light waves.
