|
Prokaryote
|
No Nucleus; Single circular strand of DNA
|
|
|
Eukaryote
|
DNA in a membrane - bound structure (Nucleus)
|
|
|
Cell Walls
|
Porous, polysaccharide; net-like
|
|
|
Plasma Membranes
|
Differentially permeable
|
|
|
Cytoplasm (Protoplasm)
|
Colloidial, jelly-like substance composed mostly of water
|
|
|
Endoplasmic Reticulum (ER)
|
Membranous network of tubules in cytoplasm
|
|
|
Plastids
|
Chloroplasts, chromoplasts, leucoplasts
|
|
|
Nucleus
|
Defining organelle of eukaryotes; separates DNA physically and chemically from the cytoplasm
|
|
|
Mitochondria
|
an organelle; "cellular power plants," because they convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation
|
|
|
Flagella
|
Long, whip-like motile structure that projects from a cell
|
|
|
Cillia
|
A motile or sensory structure that projects from the plasma membrane of certain eukaryotic cells
|
|
|
Vesicles
|
store, transport, or digest cellular products and wastes.
|
|
|
Lysosome
|
Vesicle filled with enzymes that functions in intracellular digestion
|
|
|
Vacuoles
|
membrane-bounded compartments within some eukaryotic cells that can serve a variety of secretory, excretory, and storage functions
|
|
|
Centrioles
|
organise the pericentriolar mateial (PCM) which plays a role in organizing the mitotic spindle. The mitotic spindle functions in separating the chromosomes
|
|
|
Membrane
|
a lipid bilayer that acts as a boundary to various cellular structures
|
|
|
Cell Wall
|
Of many cells, not animal cells, a semiridge but permeable structure that surrounds the plasma membrane
|
|
|
Chromosomes
|
In eukaryotic cells, one of many linear DNA molecules with attached histones and other proteins. Prokaryotic cells have one circular chromosome
|
|
|
Ribosomes
|
In all cells, a structure that translates genetic information in mRNAs into proteins
|
|
|
Golgi Bodies
|
Organelle of the endomembrane system; enzymes in it modify new polypeptide chains and assemble lipids, then package both in vesicles
|
