microscopes/cell theory
Your objective lens should start at this power when you first look at a sample
what is low power
what is the mitochondria; what is the POWERHOUSE
Another name for the phospholipid bilayer
What is the fluid mosaic model
does not contain a nucleus
what is a prokaryote
the nonpolar portion of the cell membrane
what are the fatty acid tails
you hold the microscope by these two parts
what are the arm and the base
the brain or control center of the cell
what is the nucleus
Transport of materials from a high concentration to a low concentration
what is diffusion
an example of a eukaryotic cell
what is an animal, fungus, plant, protista
the plasma membrane is inside or outside the cell wall
what is: inside
An image that appears to be 3D is taken with what microscope
What is a Scanning Electron Microscope (SEM)
packages and ships proteins around and out of the cell
what is the golgi apparatus
The hydrophobic region of the phospholipid
What is the fatty acid tail
an example of a prokaryotic cell
what is bacteria
type of cell that contains a cell wall
what is a plant cell
to find total magnification, you multiple these two things
what are the objective lens power and the eyepiece magnification
breaks down and digests materials in the cell
what are lysosomes
The bulk transport of material out of the cell
what is exocytosis
contains membrane bound organelles
what is eukaryotic
Where would water diffuse to in in a hypotonic solution?
What is: into the cell
at least two points of cell theory
1. cells are the basic unit of life
2. all organisms are made of cells
3. all cells come from preexisting cells
transports materials around the cell
what are vesicles (vesicle=vehicle)
what solution would cause a cell to shrink (water leaves the cell)
what is a hypertonic solution
The 4 organelles present in all cells
What are: ribosomes, DNA, cell membrane, and cytoplasm
the 3 organelles ONLY in plants
what are chloroplast, cell wall, and large central vacuole
