Parts of the Cell Membrane Transport Organelles Osmosis Miscellaneous
100
What is the cell membrane
This is made up of the phospholipid bilayer and proteins
100
What is selective permeability
This term describes the cell membranes ability to allow some molecules to pass through while keeping others out
100
What is the nucleus
This organelle houses the cells DNA
100
What is water
This will move from an area of high solute concentration to an area of low solute concentration during osmosis
100
What are microvilli
These are membrane extensions that increase surface area
200
What is mitochondria
This organelle enables the cell to undergo functions requiring energy by producing ATP
200
What is osmosis
The diffusion of water through a membrane
200
What is the endoplasmic reticulum
This can be classified as smooth or rough, depending on whether or not ribosomes are present
200
What is hypotonic
This is what a solution is called in comparison to another solution with a higher solute concentration and the net movement of water is out of the solution
200
What is a cell-adhesion molecule
This type of membrane protein enables a cell to anchor and connect to another cell
300
What are ribosomes
These are granules of protein and RNA that can be found in the cytosol, nucleoli, and the rough ER
300
What is active transport
This is the process of moving molecules against their concentration gradient, requiring ATP
300
What is the Golgi complex
This organelle is responsible for forming lysosomes, secretory vesicles, and new plasma membrance
300
What is hypertonic
This is what a solution is called in comparison to another solution with a lower solute concentration and the net movement of water is into the solution
300
What is passive
Filtration and simple diffusion both classify as this type of transport
400
What is a peroxisome
This organelle is similar to a lysosome but contains different enzymes
400
What is carrier mediated transport
This is when proteins carry solutes across a cell membrane and can be classified as either facilitated diffusion or active transport
400
What is the cytoskeleton
This organelle provides structure and rigidity to the cell
400
What is isotonic
This is what a solution is called when it has the same solute concentration as the solution it is being compared with and there is no net movement of water
400
What is transcytosis
The movement of a substance across a cell using both endocytosis and exocytosis
500
What are centrioles
These form the centrosome and play a role in cell division
500
What is vesicular transport
This is the process of moving large molecules through the membrane in vesicles that requires ATP
500
What is the lysosome
This organelle is responsible for the break down of glycogen in the liver to be released as glucose
500
What is tonicity
This is the ability of a solution to affect the fluid volume and pressure within a cell
500
What is an antiporter
These proteins allow the movement of two molecules in opposite directions across a cell membrane
