○ isotonic
■ no movement of__________
active
● requires__________
● 3 types
○ protein pumps
○ endocytosis
■ cell uses a________ to bring molecules________ the cell
○ exocytosis
■ cell uses a vesicle to bring molecules__________ of the cell

Explanation:

Cell transport is a fundamental concept in biology. The two main types are passive and active transport. Passive transport does not use energy. Osmosis is the movement of water, diffusion is the movement of molecules from high to low concentration. Facilitated diffusion uses transport proteins. In hypertonic solutions, water moves out of the cell and it shrivels. In hypotonic solutions, water moves into the cell and it swells. In isotonic solutions, there is no net movement of water. Active transport requires energy. Endocytosis uses a vesicle to bring molecules into the cell. Exocytosis uses a vesicle to bring molecules out of the cell.

Answer:

Two types of cell transport are passive transport and active transport.
Passive:

• Does not use energy
• 3 types
• Osmosis - the movement of water
• Diffusion - the movement of molecules (from high to low concentration)
• Facilitated diffusion - the movement of molecules using transport proteins
• Osmotic solutions
• Hypertonic
• water moves out of the cell, cell shrivels up
• Hypotonic
• water moves into the cell, cell swells
• Isotonic
• no movement of water (net movement)

Active:

• Requires energy
• 3 types
• Protein pumps
• Endocytosis
• Cell uses a vesicle to bring molecules into the cell
• Exocytosis
• Cell uses a vesicle to bring molecules out of the cell
