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 function of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, maintaining their shape.

Front

What are lysosomes?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.

Front

What is the role of the plasma membrane?

Back

The plasma membrane regulates what enters and exits the cell, maintaining homeostasis.
