What is the function of the vacuole in plant cells?

Back

The vacuole stores water, nutrients, and waste products. It is larger in plant cells and helps maintain turgor pressure.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that use sunlight to produce food (glucose) through the process of photosynthesis.

Front

Which organelles are unique to plant cells?

Back

Chloroplasts and cell walls are organelles that are only found in plant cells.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they convert sugars into energy (ATP) that the cell can use.

Front

What is the cell wall?

Back

The cell wall is a rigid outer layer found in plant cells that provides structure and protection.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis in the cell, where amino acids are assembled into proteins.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is cytoplasm?

Back

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