1
Ribosomes
Sites of protein synthesis
2
Microfilaments
Part of the cytoskeleton that is made of actin
3
Nucleoid
The region where DNA is found in prokaryotic cells
4
Middle lamella
The area between plant cell walls that "glues" the cells together
5
Scanning Electron Microscope
A type of electron microscope that looks that the external structures of the cell
6
Lysosomes
Digestive centers of the cell; sacks of enzymes
7
Integrins
Proteins that go all the way through the membrane; they communicate between the ECM and the cytoskeleton
8
Nucleus
Control center of eukaryotic cells
9
Cellular Respiration
Process that breaks down chemical energy (food) into ATP. This occurs in mitochondria in eukaryotic cells.
10
Cis face
Receiving side of the Golgi apparatus
11
Chromosomes
The form that DNA is in right before cell division. these are found in the nucleus
12
Prokaryote
The earliest and simplest type of cell; lacks membrane bound organelles and a nucleus
13
ECM
The structure that is on the outside of animal cells; it helps with structure and is made mostly of glycoproteins
14
Dynein Arms
Motor molecules that help move microtubules in cilia and flagella
15
Desmosomes
Anchoring junctions, these structures hold animal cells together in strong sheets
16
Photosynthesis
Process that turns light energy into chemical energy in autotrophs. It takes place in chloroplasts
17
ER
This organelle makes membranes and also helps to move substances around in the cell.
18
Eukaryotes
More highly specialized cells: they have a nucleus and membrane bound organelles; plant and animal cells are examples of this
19
Nucleolus
Structure in the nucleus that produces RNA (which eventually makes ribosomes)
20
Mitochondria
Powerhouse of the cell
Site of cellular respiration
21
Secondary Cell Wall
This is found under the primary cell wall to strengthen it; it is very strong and wood is an example of it
22
Cytoskeleton
Structural support in cells
23
Contractile Vacuole
A structure in animal cells that gets rid of excess water to prevent the cells from bursting in hypotonic solutions
24
Primary cell wall
The thin and flexible cell wall that is pliable until the plant stops growing. Once it stops growing, it hardens.
25
Cytoplasm
Everything between the nucleus and plasma membrane in eukaryotic cells; made up of cytosol and organelles.
26
Transfer Electron Microscope
A type of electron microscope that looks at the internal structures of the cells
27
Chromatin
The form that DNA is in for most of the cell cycle; long, thin strands
28
Trans face
The shipping side of the Golgi
29
Peroxisomes
Organelles that break down hydrogen peroxide into water and oxygen; this helps cells in the liver detoxify drugs and alcohol
