The correct answer is A) Red algae, Brown algae, and yellow-green algae.
Chlorophylls 'c', 'd', and 'e' are specialized pigments found in different groups of algae and are not typically found in higher plants. These pigments are involved in photosynthesis but are distinct from the chlorophyll 'a' and 'b' found in most plants.
Chlorophyll 'c', 'd', and 'e':
• Chlorophyll 'c': Found in brown algae (such as kelps) and diatoms, chlorophyll 'c' helps in absorbing light in the blue and red wavelengths, aiding in photosynthesis.
• Chlorophyll 'd': This pigment is characteristic of red algae. Chlorophyll 'd' absorbs light in the far-red region of the spectrum and is used by certain species of red algae for photosynthesis.
• Chlorophyll 'e': Found in yellow-green algae, chlorophyll 'e' helps in photosynthesis by absorbing light in the red and blue-green wavelengths.
Now, let’s review the other options:
• B) Brown algae, Red algae, and yellow-green algae: This option is incorrect because it incorrectly matches the pigments with the algae groups. Chlorophyll 'c' is in brown algae, but chlorophyll 'd' should be associated with red algae, and chlorophyll 'e' with yellow-green algae. So, this is a wrong match.
• C) Diatoms, Dinoflagellates, Euglena: This option is incorrect. While diatoms do contain chlorophyll 'c', dinoflagellates and euglena have other types of pigments, like chlorophyll 'a' and 'b'. Chlorophyll 'd' and 'e' are not characteristic of these groups.
• D) Higher plants, Red algae, Diatoms: This option is incorrect because higher plants do not contain chlorophyll 'c', 'd', or 'e'. They have chlorophyll 'a' and 'b'. The other groups mentioned (red algae and diatoms) do contain chlorophyll 'd' and 'c', respectively, but not in the correct order for the option.
Chlorophyll 'c', 'd', and 'e' are characteristic pigments of red algae, brown algae, and yellow-green algae, respectively, making A) Red algae, Brown algae, and yellow-green algae the correct answer.
