GenBio Eukaryotic vs. Prokaryotic
simple, single-celled organism without a defined nucleus
primitive type of cell that is characterized by the ABSENCE of the NUCLEUS
Prokaryotic cells
Prokaryotic cell does not have nuclear membrane. However the "genetic material is present in a region in the cytoplasm known as _______
nucleoids
-it is an outer covering
-moisture retention and protects the cell
capsule
-outermost layer of the cell
-give shape of the cell
Cell Wall
composed of enzymes and gell-like components
cytoplasm
entry and exit of the substance in cell
cell membrane
Hair-like outgrowths
Pili
long function
helps in LOCOMOTION of the cell
flagella
involved in protein synthesis
ribosomes
non-chromosomal DNA structures
plasmids
region in the cytoplasm where genetic material is PRESENTED
nucleoid region
absence of a true NUCLEUS and presence of a FLAGELLUM
Prokaryotic cell diagram
genetic material of the cell
DNA
contais a membrane bound nucleus and organelles
eukaryotic cells
separates the cell from the outside environment
plasma membrane
rigid structures that is absence from animal cell
provide shape of the cell
cell wall
presented inside the cytoplasm
consist of microfilaments, microtubules, and fibers
cytoskeleton
a network of small tubular structure
endoplasmic reticulum
contains DNA and Protein
nucleus
flat-disc structure called cisternae
golgi apparatus
main site of protein synthesis
ribosomes
powerhouse of the cell because they produce energy
mitochondria
know as 'suicidal bags they produce hydrolytic enzymes
lysosomes
double-membraned structure ls are found only in plants cells
plastids
3 types of plastids
chloroplast
chromoplast leucoplast
contains chlorophyll
chloroplast
contains pigment called carotene (yellow, red, orange)
chromoplast
colorless and store oils
leucoplast
