What organelle produces food through photosynthesis using the sun's light energy (ONLY IN PLANT CELLS)?

Back

Chloroplasts

Front

Where will the water go if a cell is placed in a hypertonic solution?

Back

Front

What is the result of diffusion across a semi-permeable membrane?

Back

Equal concentrations on both sides of the semi-permeable membrane.

Front

What type of cell is characterized by the absence of a nucleus?

Back

Prokaryote because it has no nucleus.

Front

What happens to the secretion of glucagon when blood sugar is high?

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.

Front

What is osmosis?

Back

The movement of water molecules through a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are the powerhouse of the cell, producing energy through cellular respiration.
