Cell membrane and Cellular Transport

Moving from areas of LOW concentration to areas of HIGH concentration is called?

• Passive Transport
• Active Transport
• Diffusion
• Osmosis

Our cell membrane only lets certain substance in and out of the cell.  This is called?

• Semi-Selectively Permeable
• Perforated
• Non-conductive
• Permeable

What means of particle transport requires energy?

• passive
• active
• facilitated
• osmosis

What is the diffusion of water through a selectively permeable membrane?

• active transport
• osmotic pressure
• facilitated diffusion
• osmosis

Diffusion is the movement of particles

• from low to high concentration
• from  high to low concentration
• from equilibrium to areas of high concentration
• all of the above

What is it called when a cell is placed in a solution that has a greater concentration on the outside of the cell than inside?

• Hypotonic
• Hypertonic
• Isotonic
• Osmosis

____ is the molecule that provides energy for active transport.

• DNA
• ADP
• ATP
• RNA

When there is the same concentration of solute molecules outside the cell as inside.

• Hypotonic
• Hypertonic
• Isotonic
• Homeostasis

Which type of transport does NOT require energy?

• osmosis

• passive transport

• diffusion

• All are correct

How long does diffusion last?

• Until the concentration of particles in the system is equal

• (Select this answer and I swear i'll make it harder for you in the assessment task)

• Until a region in the system has a greater concentration of particles than the other

• Until the particles disappear from the system
