The movement of substances from an area of higher concentration to an area of lower concentration is called ___________.
diffusion
osmosis
cellular respiration
When molecules pass through a cell membrane using special proteins called transport proteins, the process is called _____________.
Diffusion
osmosis
facilitated diffusion
active transport
Which of these is a type of protein that can assist molecules through the cell membrane?
channel protein
carrier protein
Both of these
None of these
The movement of substances through a cell membrane by using energy is called _____________.
passive transport
inactive transport
active transport
facilitated transport
The movement of substances through a cell membrane without using the cell's energy is called _____________.
osmosis
passive transport
active transport
diffusion
The process during which a cell's vesicles release their contents outside the cell is called ___________.
Exocytosis
Endocytosis
Osmosis
What causes the red dye particles to diffuse through the membrane?
Particles move from an area of lower concentration to an area of higher concentration
Particles move from an area of higher concentration to an area of lower concentration
Particles move from an area of higher energy to an area of lower energy.
Particles move from an area of lower energy to an area of higher energy
What keeps cells from growing too large?
If a cell gets too large, there is not enough energy available for passive transport.
If a cell gets too large, there is not enough energy available for active transport
If the surface-area-to-volume ratio is too small, not enough nutrients can move across the membrane.
The movement of WATER across a selectively permeable membrane without the use of energy is called __________.
active transport
osmosis
diffusion
endocytosis
Why are there more red dye particles in the right side of the membrane after 30 minutes?
The membrane allowed active transport to take place.
The membrane is not like the cell membrane, so the dye can get through.
Only dye particles could move through the membrane.
Some of the dye molecules diffused through the membrane.
