Cellular Transport Review

Movement of particles through the cell membrane from high to low concentrations

• diffusion
• photosynthesis
• mitochondria
• active transport

Against the concentration gradient
low to high uses energy/ATP

• facilitated diffusion
• osmosis
• active transport
• diffusion

Allows certain molecules or ions to pass through it by diffusion and doesn't allow others.

• protein
• semi-permeable membrane
• isotonic
• homeostasis

Equal percentage of solutes inside and out. 
Concentration of substances is the same. 

• hypotonic
• isotonic
• nucleus
• hypertonic

Particles are too large to enter the membrane.
Need help from channel proteins. No energy required.

• active transport
• passive transport
• facilitated diffusion
• osmosis

Diffusion of water across a cell membrane
from high to low.

• osmosis
• active transport
• protein channel
• pinocytosis

Engulfs large molecules and moves them inside the membrane.
Uses energy.

• exocytosis
• endocytosis
• protein channel 
• diffusion

Engulfing a large substance from the inside of the cell to move it outside of the cell. 
Uses energy. 

• exocytosis
• endocytosis
• photosynthesis
• diffusion

Particles move from high concentrations to low concentrations.
Doesn't need energy

• passive transport
• facilitated transport
• active transport
• exocytosis

Cell is placed into a concentration of water that has the same makeup as the cell. The cell will 

• Explode
• Shrink
• Stay the same
• None of the above
