  • Question 1
    1 / -0
    Alginic acid is produced by
    Solution
    • Alginic acid, also called as algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where through binding with water it forms a viscous gum. 
    • In extracted form, it absorbs water quickly; it is capable of absorbing 200-300 times its own weight in water. 
    • It is sold in filamentous, granular or powdered forms.
    • Hence the correct option is D.
  • Question 2
    1 / -0
    Sea weeds are a source of
    Solution
    • Seaweeds are among the most potent accumulators of iodine. Kelps of the Laminaria genus were identified as a major iodine source. 
    • Iodine is found at low concentrations throughout the ocean waters, many types of seaweed accumulate the element in very high levels. 
    • It has been suggested that seaweeds could be an important route to transfer iodine to the atmosphere.
    • Thus. option D is correct. 
  • Question 3
    1 / -0
    Largest unicellular organism is
    Solution
    • Acetabularia is the largest unicellular organism. 
    • Acetabularia is a genus of green algae, specifically of the Polyphysaceae family. 
    • It is typically found in subtropical waters. 
    • Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. 
    • Thus, the correct answer is option B.
  • Question 4
    1 / -0
    Which of the following red algae are suitable for human consumption?
    Solution
    • The marine red alga Porphyra has been cultivated extensively in many Asian countries as an edible seaweed used to wrap the rice and fish that compose the Japanese food sushi and the Korean food kimbap. 
    • Rhodymenia sps are also consumed as food either in raw or cooked form and its products are used as thickening agents in food preparations.
    • So, the correct answer is "Rhodymenia and Porphyra'.
  • Question 5
    1 / -0
    Which one has good capacity of absorbing water, used in place of cotton and as a fuel?
  • Question 6
    1 / -0
    What is incorrect for brown algae?
    Solution
    • Brown algae belong to the class Fucophyceae, which is formerly known as Phaeophyceae. 
    • In brown algae, the photosynthetic pigments are Chlorophyll a, c and carotenoids. 
    • They vary in colour from Olive green to various shades of brown depending upon the amount of xanthophyll pigment "fucoxanthin" present in them. 
    • The vegetative body of brown algae such as in the order Laminariales is morphologically distinguished into holdfast, stipe and blade. The holdfast helps in the attachment of the thallus to the substratum.
    • So, the correct answer is C.
  • Question 7
    1 / -0
    Halophilic green alga Dunaliella stores
    Solution
    • Dunaliella is a halophilic alga and it does not possess a rigid cell wall.  
    • To survive, the organism uses a high concentration of glycerol to maintain or to protect it against the osmotic pressure.
    • So, the correct answer is "Glycerol'.
  • Question 8
    1 / -0
    Which is peat moss?
    Solution
    Answer: (A) $$\textit Sphagnum$$.
    Explanation:
    • $$\textit Sphagnum$$ is a moss comes under division bryophyta.
    • Dead, dried, and decayed sphagnum moss is converted into a peat bog.
    • Most of the dead material in a peat bog comes from $$\textit Sphagnum$$ moss.
    Hence,$$\textit Sphagnum$$ is known as the peat moss. 

  • Question 9
    1 / -0
    Which of the following sets belongs to the same class of algae?
    Solution
    • The group of the green algae consists of the Chlorophyta together with the charophytae. 
    • Common representatives of the Chlorophyta are Chlamydomonas, Volvox and Ulva. Well-known representatives of the charophyta are Spirogyra, Zygnema and Desmides.
    • So, the correct answer is 'Volvox, Spirogyra, Chlamydomonas'
