Question

Consider the following statements.
A. Almost all animals are either herbivores or carnivores.
B. Human beings, rats, crow etc., are omnivorous.
C. Holozoic mode of nutrition is seen in Amoeba and Paramecium.
D. Lysosome involved in the digestion of engulfed food is seen in the contractile vacuole of Amoeba.
Which of the above statements are incorrect?

• A. A, C and D
• B. A, B and D
• C. A and D
• D. B and D

Answer 1

The correct option is C A and D

Almost all animals fall under either herbivores, carnivores or omnivores category. Herbivores like horses eat plants. Carnivores like lions eat meat. Omnivores eat plants and meat. Examples of omnivores include human beings, dogs, pigs, walking catfish, rat, crow, etc. Holozoic nutrition is a type of heterotrophic nutrition in which ingestion and digestion of food take place. Examples of organisms having the holozoic mode of nutrition are protozoa such as amoeba, humans, paramecium, etc. The lysosome is involved in digestion and destruction. In amoeba, food is engulfed in the form of food vacuole. Lysosome combines with food vacuole and breaks down food particles into simpler ones. Contractile vacuole expels excess water that has been accumulated in the cytoplasm. Thus, the correct answer is option C.
