Membranes
This model states that the membrane is a fluid structure with proteins embedded in it.
The fluid mosiac model
Moving a material across a membrane when energy isn't required is this type of diffusion.
Passive
This protein allows the flow of molecules in two directions, moving one molecule to the inside and moving another to the outside.
Antiporter
A eukaryotic cell has a nucleus. A prokaryotic cell has this instead.
Nucleoid
This mostly liquid component makes up the "filler" inside of a cell.
Cytosol or cytoplasm
This process moves items from inside the cell to outside the cell, an opposite of endocytosis.
Exocytosis
This term refers to having more solute outside of the cell than inside.
Hypertonic
To move a substance against its concentration gradient you must have this.
Energy (ATP)
Along with magnification, these two parameters are important in microscopy.
Resolution (clarity) and contrast (visual difference)
These little sac-like organelles move things around a cell, and also help move things into and out of a cell.
Vesicles
This substance helps to stabilize membranes by inserting itself into the bilayer.
Cholesterol
A red blood cell has no cell walls, so when it is placed in a hypotonic solution it will do this...
Lyse
If you want to eat an entire cell up, then this method of endocytosis is the way to go.
Phagocytosis ("cellular eating")
Chromatin condenses into this...
Chromosome
Plants use these large organelles to regulate their water concentrations.
Central vacuole
Made of a protein and a carb, these surface molecules help in cell-to-cell recognition.
Glycoproteins
In facilitated diffusion, these particles help move molecules across the plasma membrane.
Transport proteins
A form of endocytosis that requires ligands to bind to a protein.
Receptor-mediated endocytosis
The idea that all cells must arise from a pre-existing cell is the basis of this theory.
The Cell Theory
Its the organelle that makes proteins.
Ribosome
This is the name of a protein in the plasma membrane that spans the entire width from the inside of the cell to the outside.
Transmembrane protein
How the volume of a cell can change based on its extracellular osmolarity is called this...
Tonicity
This form of transport relies on another active transport process place occurring first.
Secondary Active Transport
Its the pigment found in a cholorplast.
Chlorophyll
Roughly speaking, this organelle is a membrane factory for a cell.
Rough ER
