(59 cards)
Barrier between external and internal environment. An area where things can go in and out
Plasma membrane
Keeps the DNA molecules separate from metabolic machinery of the cytoplasm. Makes it easier to organize DNA and copy it
The nucleus
Site of translation : made of rna and proteins
Ribosomes
Synthesis, storage, and shipping of molecules
Endomembrane system
Processes proteins and makes membrane
Rough endoplasmic reticulum
Makes lipids,detoxification
Smooth Endoplasmic reticulum
Finishes making proteins and lipids that arrive and sends them to where they need to go
Golgi body
Transport material from organelle and plasma membrane, then breaks down waste
Vesicles
Produces ATP through cellular respiration, then uses energy and turns it into a useable form
Mitochondria
Converts sunlight energy into ATP through photosynthesis
Chloroplast
Network of protein fibers within a cell that defines the shape and provides strength. Gives movement.
Cytoskeleton
A cytoskeleton, acts as “railroads” with movement within a cell
Microtubules
A cytoskeleton, comprised of the protein actin
Microfiliments
Microtubule organizing center, help with cell division.
Centrosome and centriole
Slender and flexible structure functioning in motility. Used to move things around the cell. Hair like
Cilia and flagella
Protection and adherence. Cell to cell communication
Glycocalxy
Provides support and protection. Not in animals
Cell wall
How big you can blow something up
Magnification
Minimum distance to distinguish between two points
Resolution
Visible shades in the object
Contrast
All life is composed by one or more cells
