Which classes of algae possess pigment fucoxanthin and pigment phycoerythrin, respectively?
1 Chlorophyceae and Rhodophyceae
2 Rhodophyceae and Phaeophyceae
3 Phaeophyceae and Chlorophyceae
4 Phaeophyceae and Rhodophyceae
Explanation:
Fucoxanthin is a xanthophylls carotenoid abundant in macro algae, such as brown sea weeds (pheophyceae). - Phycoerythrin is a major light- harvesting pigment of red algae and cyanobacteria. - The pheophyceae photosynthetic pigments include chlorophyll $\mathrm{A}, \mathrm{C}$ and $\beta$ carotene and xanthophylls like fucoxanthin. - Fucoxanthin partially mask the chlorophyll and carotenoid there by giving the characteristic brown coloration. - Rhodophyceae (Red algae) photosynthetic pigments chlorophyll A and D and biliproteins such as rphycoerythrin and r-phycocyanin.

Agarose is a natural polymer extracted from
1 Fungi
2 Bryophytes
3 Sea Weeds
4 Pteridophytes
Explanation:
D-galactose and 3, 6 anhydro-L-galactose are the two sugar that make up the natural polymer agarose, which is made from red algae, or seaweed. Agarose is a main component as agar, which is a polysacharide extracted from seaweed. - Agarose is most commonly used as the medium for analytical scale electrophoretic seperation in agarose gell electrophoresis gell made from purified agarose have a relativily large pore size, making them useful for seperation of large molecule such as proteins and protein complexes as well as DNA fragments.

Air bladders are found in the following plant
1 Fucus
2 Laminaria
3 Dictoyota
4 Polysiphonia
Explanation:
Fucus is marine brown algae which belong class phaeophyceae. Plant body of fucus differentiated into basal discoid holdfast which anchors it to the substratum, a short stipe and a flattened, dichotomously branched frond. - Air bladders occurs in the upper portion of the frond that give bouncy to the plant.

Which of the following is incorrectly matched?
1 Volvox - Starch
2 Ectocarpus - Fucoxanthin
3 Ulothrix - Mannitol
4 Porphyra - Floridian Starch
Explanation:
Volvox is a member of chlorophyceae which is known as green algae. It contains starch. Ectocarpu is a member of phoeophyceae, they contain fucoxanthin and found in marine habitats. Ulothrix is a member of cholorophyceae and contains starch. Mannitol is brown-algae and basically store food material. Porphyra comes in the family of Rhodophyceae and contain floridian starch. Hence option (c) is incorrectly matched.
