Cell Transport

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion

an important “energy molecule” found in all life forms.

• ATP

• Enzyme

• Carbohydrate

• Lipid

the passive movement of molecules or particles from regions of higher to regions of lower concentration

• Diffusion

• Active Transport

• Facilitated Diffusion

• Osmosis

any self-regulating process by which biological systems tend to maintain stability

• Metabolism

• Homeostasis

• Meiosis

• Mitosis

 is the gelatinous liquid that fills the inside of a cell

• Mitochondria

• Chloroplast

• Ribosome

• Cytoplasm

a rigid layer of polysaccharides lying outside the plasma membrane of the cells it consists mainly of cellulose

• Cell Membrane

• Cell Wall

• Nucleus

• Capsid

allowing certain substances to pass through it but not others

• Permeable

• Open

• Active Transport

• Semi-Permeable

the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules

• Facilitated Diffusion

• Osmosis

• Active Transport

• Diffusion

occurs when the concentration of particles is higher in one area than another

• Protein Channel

• Diffusion

• Osmosis

• Concentration Gradient

a double layer of phospholipids and proteins that surrounds a cell. It separates the cytoplasm (the contents of the cell) from the external environment.

• Cell Wall

• Nucleus

• Cell Membrane

• Chloroplast
