Current Question (ID: 12135)

Question:

In the given diagrams, some of the algae have been labelled as A, B, C, D and E. Choose the correct option to identify these algae.

Options:

1. Dictyota, Polysiphonia, Porphyra, Fucus, Laminaria
2. Porphyra, Dictyota, Laminaria, Fucus, Polysiphonia
3. Dictyota, Polysiphonia, Porphyra, Laminaria, Fucus
4. Fucus, Porphyra, Dictyota, Polysiphonia, Laminaria

Solution:

Algae are chlorophyll containing thallophytes which may be unicellular, colonial filamentous, parenchymatous and pseudoparenchymatous. Based on their pigments, flagellation and storage products algae are divided into three main classes: chlorophyceae, phaeophyceae and rhodophyceae. Laminaria, Fucus and Dictyota are phaeophyceae (Brown algae). Porphyra and Polysiphonia are Rhodophyceae (red algae).
