Question

Regarding the assertion and reason; choose the correct option.

Assertion [A]: Salivary glands and intestinal glands are intrinsic glands.

Reason [R]: They aid in intracellular digestion.

• A. [A] is True and [R] is False.
• B. [R] is True and [A] is False
• C. [A] and [R] are True, and [R] is a correct explanation to [A]
• D. [A] and [R] are True, but [R] is not a correct explanation to [A].

Answer 1

The correct option is A

[A] is True and [R] is False.

The Assertion [A] is right. Salivary glands and intestinal glands are intrinsic glands because they are present inside the alimentary canal. Glands present outside the alimentary canal, such as liver, pancreas etc are extrinsic glands. But they do not aid in intracellular digestion. Intracellular digestion is a type of digestion that takes place inside a cell, this usually happens only in lower forms of organisms, unicellular protists like the amoeba, paramecium etc. Humans, however, have complete and extracellular digestive systems, where the digestion takes place in a body canal called the alimentary canal, and only the digested and assimilated nutrients enter inside human cells. Therefore the Reason [R] is wrong.
