Cell Transport 1
a type of cellular transport in which materials move across the cell membrane without the use of energy
passive transport
the diffusion of water molecules across the cell membrane is known as
osmosis
occurs when large or charged molecules move across the cell membrane from high to low concentration. These molecules must use a protein channel (bridge) to get through the cell membrane
facilitated diffusion
If humans received IV's full of 100% purified water, it would cause our blood cells to swell and possibly burst. The IV would be considered _________
hypotonic
a type of cellular transport in which materials move across the cell membrane using ATP energy
Active Transport
a transport bubble that moves material throughout the cell is known as a
vesicle
hypotonic
When a cell is in a state in which concentrations on the inside and outside are even, it has reached _______________
equilibrium
the process by which cells use glucose to create ATP energy. this occurs in the mitochondria
cellular respiration
when the cell membrane surrounds a large particle, creating a vesicle around it, and brings it into the cell it is know as ______
endocytosis
A cell is surrounded by a solution in which the water concentration is higher inside the cell than in the solution. Water will move out of the cell. This solution should be labeled as _____________
hypertonic
Sodium-Potassium pumps are located in our cell membrane to keep sodium and potassium concentrations equal. These pumps use ATP energy. What type of cellular transport is occurring?
Active Transport
process in which plant cells make glucose using energy from the sun. this occurs is chloroplasts.
photosynthesis
when the cell uses a vesicle to push large particles out of the cell is known as
exocytosis
isotonic
The cell membrane is called a phospholipid bilayer because it is made of ___________ and _________
phosphates and lipids
__________ occurs when particles move from high concentration to low concentration directly across the cell membrane without any assistance
simple diffusion
the cell membrane is considered ___________ bc it determines what can go into and out of the cell
selectively permeable
After hurricane Milton hit Florida, many plants located near the ocean began to die. This is due to the large amount of salt water brought to land. The salt water caused plants to lose their own water and die. How would you describe the environment compared to the plant in this case?
hypertonic
When we breathe in oxygen, it travels the blood stream and diffuses directly into our cells without the use of energy. What type of transport is this?
simple diffusion
