What is the function of a vacuole in plant cells?

Back

Vacuoles in plant cells are responsible for storing nutrients, waste products, and helping maintain turgor pressure.

Front

How do camel cells differ from corn plant cells in terms of vacuole size?

Back

Camel cells have a small vacuole size because they do not need long-term water and electrolyte storage, while corn cells have a larger vacuole to store water and remove toxins.

Front

What structure protects the DNA within a cell?

Back

The nucleus protects the DNA within a cell.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of high concentration to an area of low concentration.

Front

Which organelles are responsible for protein production and sorting?

Back

Ribosomes, the endoplasmic reticulum, and Golgi apparatuses are responsible for the production and sorting of new proteins.

Front

How does the cell membrane maintain homeostasis?

Back

The cell membrane maintains homeostasis by regulating the movement of substances in and out of the cell.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane help transport large and polar molecules across the membrane barrier.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration without the need for energy.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.
