Flashcard #9- Cell Membrane and Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, moving from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane using energy, moving from an area of lower concentration to an area of higher concentration.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing structure and protection.

Front

What are the two types of cells?

Back

The two types of cells are Prokaryotic cells and Eukaryotic cells.

Front

What is a Prokaryotic cell?

Back

A Prokaryotic cell is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.

Front

What is a Eukaryotic cell?

Back

A Eukaryotic cell is a complex cell that has a nucleus and membrane-bound organelles.

Front

What organelle is responsible for digesting waste?

Back

The lysosome is responsible for removing and digesting wastes in the cell.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane.

Front

What is the role of proteins in active transport?

Back

Proteins act as pumps to move substances across the cell membrane during active transport.
