What is the function of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and it also transports materials within the cell.

What is the large central vacuole's function in plant cells?

Back

The large central vacuole stores water, nutrients, and waste products, and helps maintain turgor pressure in plant cells.

Front

What is the role of centrioles in cell division?

Back

Centrioles help organize the mitotic spindle and are essential for pulling chromosomes apart during cell division.

Front

Why do different cells have different shapes?

Back

Different cells have different shapes to fit their specific functions, such as muscle cells being elongated for contraction.

Front

What is the plasma membrane?

Back

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

Front

What is the function of lysosomes?

Back

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