Cells and Cell Transport

Front

What is Filtration in cell transport?

Back

Filtration is the process that uses pressure to push substances through the cell membrane, allowing smaller molecules to pass while blocking larger ones.

Front

Does active transport require energy?

Back

No, active transport requires energy to move substances against their concentration gradient.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, small cells that lack a nucleus and membrane-bound organelles, but they do have a cell wall.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of the cell membrane?

Back

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

Front

What is active transport?

Back

Active transport is the process of moving 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 passive movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf substances from their external environment, bringing them into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles, releasing them into the external environment.
