Chapter 6 Flashcards
(46 cards)
Ribosomes
Sites of protein synthesis
Microfilaments
Part of the cytoskeleton that is made of actin
Nucleoid
The region where DNA is found in prokaryotic cells
Middle lamella
The area between plant cell walls that “glues” the cells together
Scanning Electron Microscope
A type of electron microscope that looks that the external structures of the cell
Lysosomes
Digestive centers of the cell; sacks of enzymes
Integrins
Proteins that go all the way through the membrane; they communicate between the ECM and the cytoskeleton
Nucleus
Control center of eukaryotic cells
Cellular Respiration
Process that breaks down chemical energy (food) into ATP. This occurs in mitochondria in eukaryotic cells.
Cis face
Receiving side of the Golgi apparatus
Chromosomes
The form that DNA is in right before cell division. these are found in the nucleus
Prokaryote
The earliest and simplest type of cell; lacks membrane bound organelles and a nucleus
ECM
The structure that is on the outside of animal cells; it helps with structure and is made mostly of glycoproteins
Dynein Arms
Motor molecules that help move microtubules in cilia and flagella
Desmosomes
Anchoring junctions, these structures hold animal cells together in strong sheets
Photosynthesis
Process that turns light energy into chemical energy in autotrophs. It takes place in chloroplasts
ER
This organelle makes membranes and also helps to move substances around in the cell.
Eukaryotes
More highly specialized cells: they have a nucleus and membrane bound organelles; plant and animal cells are examples of this
Nucleolus
Structure in the nucleus that produces RNA (which eventually makes ribosomes)
Mitochondria
Powerhouse of the cell
Site of cellular respiration
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
Cytoskeleton
Structural support in cells
Contractile Vacuole
A structure in animal cells that gets rid of excess water to prevent the cells from bursting in hypotonic solutions
Primary cell wall
The thin and flexible cell wall that is pliable until the plant stops growing. Once it stops growing, it hardens.
