Terms/Notes from Slides
prokaryotes-lack membrane-bound nucleus eukaryotes-have membrane-bound nucleus
cytoplasm-surrounded by the plasma membrane, includes all
contents of the cell
cell wall-tough, for protechtion, shape, structure
supercoilling-allows 1mm (500 cell lengths) of DNA to fit inside cell
bacterial ribosome- protein-RNA structure
-fuctions: protein manufacturing
major differences betwen pro and eu
1. eu- membrame-bound nucleus
2. eu- is bigger
3. eu - extensive internal membrane
4. eu- diverse and dynamic cytoskeleton
organelles: membrane-bound structures in cell, have specific shape and function
-allow cells to have a divided cytoplasm
-increase chemical reaction efficiency by separating incompatible chemical reactions and
grouping enzymes and substrates together.
centrioles-structures that occur only in animal cells but not plant cells
rough endoplasmic reticulum
smooth endoplasmic reticulum
Figure 7.6a in book Figure 7.6b in book
Generalized plant cell
cell wall-only in plant cells
chloroplasts-only in plant cells
on average, prokaryotes are about 10x smaller than eukaryotic cell sin diameter anda bout
100times smaller than eukarotic cells in volume
nucleus- double membrane (envelope); assembles ribosome subunits, structural support,
contains genetic information
nuclear pores- openings on nuclear envelope
nucleolus-distinct region in nucleus, makes ribosomal RNA
rough endoplasmic reticulum-single membrane, continuous membrane with the nuclear
envelope, contains receptors for entry of seleted proteins, network of branching sacs,
riibosomes associated, protein sysnthesis and processing
ribosomes-no membrane; made up of large protein subunits and small RNA subunits.
large/small subunits; protein synthesis
smooth endoplasmic reticulm- single membrane, contains enzymes for synthesizing
phosolipids, network of branching sacs, enyzmes for synthesizing lipids, lipid sythesis (smooth
golgi apparatus-single membrane, contains receptors for products o
