What are the Two Major Parts of a Cell's Interior

Question

What are the two major parts of a cell's interior?
A)​the intracellular fluid and matrix
B)the nucleus and plasma membrane
C)the nucleus and cytoplasm
D)the DNA and cytoplasm
E)​the DNA and RNA

Accepted Answer

The two major parts of a cell's interior are the nucleus and cytoplasm. The nucleus contains the genetic material (DNA) and is responsible for controlling the cell's activities, while the cytoplasm contains various organelles and the intracellular fluid where many cellular processes occur. Option A is incorrect because the term "matrix" is not commonly used to describe a cell's interior. Option B is incorrect because the plasma membrane is a boundary structure that separates the cell from its external environment. Option D is incorrect because although DNA is present in the cytoplasm, it is primarily located in the nucleus. Option E is incorrect because RNA is a component of the cytoplasm, but it is not one of the major parts of a cell's interior.
