Cell transport

The movement of molecules across a membrane from high concentration to low concentration is called:

• Osmosis
• Diffusion
• Endocytosis
• Active Transport

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

• meiosis
• respiration
• diffusion
• osmosis

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell. 

• active transport
• concentration
• diffusion
• equilibrium

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport
• Passive transport
• Diffusion
• Osmosis

Cells transport material across a cell membrane without using energy (high to low concentration)

• Passive transport
• Concentration
• Endocytosis
• Active Transport

Cell membrane surrounds a particle and encloses it (for large particles)

• Endocytosis
• Exocytosis
• Permeable
• In high concentration

In passive transport, substances move across the cell membrane ________ the concentration gradient

• AGAINST

• ALONG

• WITH

• BETWEEN

When a cell forms a vesicle around unwanted particles and expels it OUT of the cell.

• Pinocytosis

• Endocytosis

• Receptor-mediated

• Exocytosis

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall

The cell below is in a _________ solution.

• Hypotonic
• Hypertonic
• Isotonic
