R4 Prokaryotic vs Eukaryotic Cell Flashcards
simple, unicelluar organism that lacks a nucleus, or any membrane-bound organelle
Prokaryote
where would you find the prokaryotic DNA and is the central part of the cell
Nucleoid
has peptodoglycan cell wall and polysaccharide capsule
Prokaryote
extra layer of protection, aid the cell maintain its shape and prevent dehydration
Cell Wall (Peptodoglycan)
enables the cell to attach to surfaces in its environment
Capsule (Polysaccharide)
used for locomotion
Flagella
exchange of genetic material during a type of reproduction (?)
Pili (conjugation)
used by bacteria to attach to a host cell
Fimbriae
diameter of prokaryotic cell and it allows what
0.1 to 5.0 um, allowing faster diffusion of ions and organic molecules, as well as wastes
diameter of eukaryotic cell and it allows what
10 to 100 um, adapted different structural adaptation to enhance intracellular transport
have membrane bound nucleus
numerous membrane-bound organelles
several rod-shape chromosomes
Eukaryotic Cell
little organ
organelles, ex endoplasmic reticulum
houses the cell’s DNA and directs ribosome and protein synthesis
stores chromatin (DNA+protein)
Nucleus
gel-like substance that stores the chromatin, in the nucleus
Nucleoplasm
condensed region of chromatin where ribosome synthesis occurs
Nucleolus
double-membrane structure that constitutes the out-most portion of the nucleus
Nuclear Envelope
punctuated with pores that control the passage of ions, molecules, and RNA between the nucleoplasm and cytoplasm
Nuclear Envelope
punctuated with pores that control the passage of ions, molecules, and RNA between the nucleoplasm and cytoplasm
Nuclear Envelope
semi-solid fluid inside the nucleus
nucleoplasm
small, round organelles enclosed by single membranes
carry out oxidation reactions that break down fatty acids and amino acids
detoxify many poisons that enter the body
Peroxisomes
specialized peroxisomes in plants, responsibles for converting stored fats into sugars
Glyoxysomes
membrane-bound sacs that function in storage and transport
vesicles and vacuoles
which among vesicles and vacuoles is larger?
Vacuoles
which membrane-bound sacs can fuse with the plasma membrane or other membrane systems
Vesicles
which membrane-bound sacs does not fuse with the membranes of other cellular components
Vacuoles
group of membranes and organelles in eukaryotic cells; to modify, package, and transport lipids and proteins
Endomembrane System
what compose the endomembrane system
nuclear envelope, lysosomes, vesicles, endoplasmic reticulum, Golgi apparatus, and plasma membrane
series of interconnected membrane sacs and collectively tubules that modify proteins and synthesize lipids
Endoplasmic Reticulum
hollow portion of the endoplasmic reticulum tubules
Lumen or cisternal space
____? membrane of the endoplasmic reticulum, a phospolipid bilayer with protein continuous to ____
Lumen or cisternal space, Nuclear Envelope
