Question

the outer boundary of a human cell is the ________.
answer options: plasma membrane, cell wall, nuclear membrane, cytoskeleton, i dont know yet

Explanation:

To solve this, we analyze each option:

• Plasma membrane: It is the outer boundary of human (animal) cells, controlling what enters and exits.
• Cell wall: Present in plant, fungal, and bacterial cells, not human cells.
• Nuclear membrane: Surrounds the nucleus, not the cell's outer boundary.
• Cytoskeleton: Provides structural support inside the cell, not the outer boundary.

So the correct answer is the plasma membrane.

Answer:

A. plasma membrane
