Question

which of the following is present in both, a plant cell and an animal cell? a. nucleus b. cell wall c. chloroplast d. central vacuole e. centrioles

Explanation:

• Nucleus: Both plant and animal cells have a nucleus. It contains the cell's genetic material and controls cellular activities.
• Cell wall: Only plant cells have a cell wall. It provides structural support and protection.
• Chloroplast: Found only in plant cells (in photosynthetic tissues). It is the site of photosynthesis.
• Central vacuole: Typically large and prominent in plant cells. In animal cells, vacuoles are smaller and less prominent.
• Centrioles: Mainly found in animal cells (and some lower - plant cells like mosses). They play a role in cell division.

Answer:

A. nucleus
