Front

What happens to blood cells when exposed to a hypertonic solution?

Back

Blood cells would shrivel up because the hypertonic solution has more dissolved particles than the cells.

Front

What is the primary function of ribosomes in a cell?

Back

Ribosomes are specialized for protein synthesis.

Front

What is a vesicle in cellular biology?

Back

A vesicle is a small membrane-bound sac that transports substances within a cell.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, such as osmosis.

Front

Do all cells have a cell wall?

Back

False, not all cells have a cell wall; for example, animal cells do not.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the function of the mitochondrion?

Back

Mitochondria are the powerhouses of the cell, responsible for energy production through cellular respiration.

Front

What is the role of the endoplasmic reticulum?

Back

The endoplasmic reticulum is involved in the synthesis of proteins and lipids.

Front

What is the difference between endocytosis and exocytosis?

Back

Endocytosis is the process of taking substances into the cell, while exocytosis is the process of expelling substances from the cell.

Front

What is the Na+/K+ pump?

Back

The Na+/K+ pump is an active transport mechanism that moves sodium out of the cell and potassium into the cell.
