Front

What is the difference between plant and animal cells?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells do not.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is the site of many metabolic processes.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing protection and structural support.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes, such as mitochondria, ribosomes, and the nucleus.
