  1. Epiploic

  2. Coenolithic

  3. Epilithic

  4. None of the above

Show answer
Correct Option: C
Explanation:

Algae growing on a rock is called as epilithic. Endolithic algae live in porous rocks or coral and chasmolithic algae grow in rock fissures. So, option C is the correct answer.

Largest unicellular organism is ___________.

  1. Yeast

  2. Acetabularia

  3. Planaria

  4. Volvox

Show answer
Correct Option: B
Explanation:
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. 
So, the correct answer is 'Acetabularia'

Plants which are mostly found on the sides of pond is

  1. Grass

  2. Algae

  3. Wheat

  4. All of the above

Show answer
Correct Option: B
Explanation:

Algae are unicellular or multicellular photosynthetic, eukaryotic organisms that can occur in salt or fresh waters, or on the surfaces of moist soil or rocks. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Hence they usually live in water or damp environments. Algal growth is a natural occurrence in all water bodies and is the base of the aquatic food chain.

So the correct option is B.

Which of the following gives shelter to grow mosquito larva?

  1. Dark box

  2. Algae

  3. Fruits

  4. None of the above

Show answer
Correct Option: B
Explanation:

Most species of algae live in the water bodies like sea, lakes, ponds, etc. Even some unicellular green algae inhabit moist conditions on land, for example - tree trunks, moist soil surface, damp walls, wetlands, swamps, etc. Usually, the insect mosquito prefers stagnant water and damp environment for laying eggs. The eggs hatch and the larvae live in water until they transform into motile pupae, from which the adult mosquito emerges. Due to this, the algae serve as an excellent shelter for growing mosquitoes. Even mosquito larvae that need constant energy to grow, eat plankton, algae, fungi and other microbes present in their habitat. Therefore, algae not only harbor mosquito larvae but also feed those growing insects. So to keep the water bodies pleasant and beautiful, algae and weeds must be regularly removed from them; as they provide growing mosquitoes with housing, nutrition, and hideaway from predators.

Phycology deals with study of

  1. Algae

  2. Fungi

  3. Microbes

  4. Bryophytes

Show answer
Correct Option: A
Explanation:

Phycology is the scientific study of algae. Phycology or Algology is a branch of life science and often is regarded as a sub-discipline of botany. Algae are important as primary producers in aquatic ecosystems. Hence, the phycology deals with the study of algae.

So, the correct answer is 'algae'.

  1. Green colour slippery appearance

  2. Spreads during rainy seasons

  3. Both A and B

  4. Heterotrophic

Show answer
Correct Option: C
Explanation:
  • Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Thus they are autotrophic.
  • Algae can be multicellular or unicellular and are characterized by the green colour slippery appearance and spread during rainy seasons.
  • So the correct option is C.
