Hint: Porphyra belongs to the phylum of Red Algae and Dictyota belong to Brown Algae. Porphyra grows in cold and shallow seawater. Dictyota are found in tropical and subtropical seas.
Complete answer:
The Rhodophyta algae phylum (also known as red algae) is considered to be one of the oldest algae species, distinguished by the presence of phycoerythrin (a complex of red protein pigments), carrageenan and phlorotannins. Porphyra is a cold water seaweed.
Fucoxanthin is a pigment of brown seaweed present in most brown algae that gives them a brown or olive-green colour and Dictyota belongs to a broad brown algae order (the Phaeophyceae class).
Option A: This is the correct option.
Option B: Xanthophyll is a yellow pigment which is found in leaves of plants like Papaya, Peaches, etc. They are naturally occurring carotenoid present in the chloroplasts. Therefore, this is an incorrect option.
Option C: Chlorophyll d and b are green pigments present in plants. They help in photosynthesis. Therefore, this is an incorrect option.
Option D: Fucoxanthin is present in Dictyota and Phycoerythrin in Porphyra. Therefore, this is an incorrect option.
Hence, the correct answer is option (A)
Note: 1.Fucoxanthin is an important marine carotenoid present in edible brown seaweeds. They help in photosynthesis and photoprotection.
2.Phycoerythrin acts as an accessory pigment to chlorophyll molecules and is produced by the phycobiliprotein family.
