Vocabulary 2.5 Review

The movement of materials through a cell membrane using energy.

• active transport

• passive transport

• diffusion

• osmosis

A cell structure that controls which substances can enter or leave a cell.

• cell membrane

• nucleus

• lysosome

• mitochondria

Movement of molecules from an area of higher concentration to an area of lower concentration.

• active transport

• endocytosis

• exocytosis

• diffusion

Process by which a cell takes material into the cell by enfolding of the cell membrane.

• exocytosis

• endocytosis

• passive transport

• osmosis

Release of substances out of a cell by the fusion of a vesicle with the membrane.

• exocytosis

• passive transport

• endocytosis

• osmosis

Diffusion of water through a selectively permeable membrane.

• active transport

• diffusion

• osmosis

• transport protein

Requires no energy, movement of molecules from high to low concentration; moves with the concentration gradient.

• active transport

• passive transport

• endocytosis

• exocytosis

Able to be passes or soaked through.

• Permeable

• Selectively permeable

• Non permeable

• osmosis

A property of cell membranes that allows some substances to pass through while others cannot.

• permeable

• selectively permeable

• Non permeable

• osmosis

Membrane proteins that help move substances across a cell membrane.

• Facilitated protein

• Low function protein

• High function protein

• Transport protein
