Question

Which of the following is an incorrect match for chlorophyll type?
A. Chlorophyll a- green algae
B. Chlorophyll d- diatoms
C. Chlorophyll c- diatoms and brown algae
D. Chlorophyll d- Red algae

Answer 1

Hint: Chlorophyll is a green photosynthetic pigment found mainly in the plants, algae and cyanobacteria. Chlorophyll absorbs in the blue light and to a lesser amount in red portions of the electromagnetic spectrum. It is the main pigment which is very essential for the photosynthetic activity of the plant.

Complete answer:
Chlorophyll is vital for photosynthesis because it allows plants to absorb energy from light. Chlorophyll molecules are embedded in the thylakoid membranes of chloroplasts present in a plant cell. The function of most of the chlorophyll (up to several hundred molecules per photosystem) is to absorb light. Chlorophyll a is essential for most of the photosynthetic organisms that release chemical energy but it is not the only pigment that can be used for photosynthesis. It is present in higher plants. All oxygenic photosynthetic organisms use chlorophyll a, but differ in accessory pigments like chlorophyll b. Chlorophyll b is an accessory photosynthetic pigment that exists in all phototrophs other than diatoms, Cyanobacteria and algae. Chlorophyll C is found in certain marine algae, including the photosynthetic Chromista (e.g., diatoms, brown algae) and dinoflagellates. Chlorophyll d is present in marine Algae, Cyanobacteria and red algae.
Hence, the correct answer is option A.

Note: The green algae are a large, informal grouping of algae consisting of the Chlorophyta and Charophyta/Streptophyta, which are now placed in separate divisions, together with the more basal Eustigmatophyceae, Chlorophyceae and Spirotaenia. The land plants, or embryophytes, are thought to have emerged from the charophytes.
