In a hypotonic solution, water moves into the cell.

Front

What is the function of the nucleus in a cell?

Back

The nucleus is the organelle that contains the cell's genetic material and controls its activities.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and leaves the cell, providing protection and support.

What are chloroplasts responsible for?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy for the plant.

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.
