Cell Structure and Function

Front

What is the function of the cell membrane?

Back

The cell membrane acts as a gatekeeper, allowing some materials to pass through while blocking others, making it semi-permeable.

Front

What organelle is responsible for breaking down lipids, proteins, carbohydrates, damaged organelles, and bacteria?

Back

Lysosomes are the organelles that perform these functions.

Front

What is a large central vacuole?

Back

A large central vacuole is a fluid-like vesicle that stores water and provides support for the cell.

Front

What is the role of the cell membrane?

Back

The cell membrane encloses the cell and regulates the movement of materials in and out of the cell.

Front

What characterizes rough endoplasmic reticulum?

Back

Rough endoplasmic reticulum has ribosomes on its membrane and is involved in transporting proteins for the cell.

Front

Define semi-permeable.

Back

Semi-permeable refers to a membrane that allows certain substances to pass through while blocking others.

Front

What is the function of lysosomes?

Back

Lysosomes contain enzymes that digest and break down waste materials and cellular debris.

Front

What is the primary function of the large central vacuole in plant cells?

Back

The large central vacuole stores water and helps maintain turgor pressure, providing structural support.

Front

What is the difference between the cell membrane and the cell wall?

Back

The cell membrane is semi-permeable and regulates entry and exit of substances, while the cell wall provides structural support and protection.

Front

What is the role of ribosomes in the rough endoplasmic reticulum?

Back

Ribosomes on the rough endoplasmic reticulum synthesize proteins that are transported within the cell.
