The structure in the diagram is a nucleus because the nucleus is a membrane-bound organelle mostly round in shape and it is present inside the cells.

The structure in the diagram cannot be cytoplasm as cytoplasm is a fluid in which organelles float.

The structure in the diagram cannot be a cell wall as a cell wall is the outer layer of a cell and it is not present inside of the cell.

The structure cannot be a flagellum as flagellum are hair-like structures. Hence, option A, C and D are false.

Correct B. Nucleus

Explanation:

Explanation: The arrow points to the nucleus of a mouse skin cell. The nucleus is a membrane-bound structure that contains genetic material. Cytoplasm (light purple) is the gel-like substance inside the cell that surrounds the nucleus. Cell walls are found in plant cells, where they provide protection and support. A flagellum is a whip-like appendage that helps some cells move.
