Cells Unit Review

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides structural support and protection to the plant cell, and is composed mainly of cellulose.

Front

What are microtubules and their role in cells?

Back

Microtubules are a component of the cytoskeleton, providing shape and support to the cell, and are involved in cell division and intracellular transport.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What are cilia and their function?

Back

Cilia are hair-like projections on the surface of some cells that help move substances across the cell surface.

Front

What is the Rough Endoplasmic Reticulum (RER)?

Back

The Rough Endoplasmic Reticulum is an organelle studded with ribosomes, involved in protein synthesis and processing.

Front

Define plasma membrane.

Back

The plasma membrane is a selectively permeable barrier that surrounds the cell, controlling the movement of substances in and out.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What are ribosomes and their function?

Back

Ribosomes are molecular machines that synthesize proteins by translating messenger RNA.

Front

Explain the difference between prokaryotic and eukaryotic cells.

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
