Organelles!
Prokaryotes
A. Prokaryotic cells are less complex
B. Unicellular
C. Do not have a nucleus & no membrane-bound
organelles
D. Most have a cell wall surrounding the cell
membrane & a single, looped chromosome (genetic
material) in the cytoplasm
E. Mostly bacteria
Eukaryotes
A. More complex cells
B. Includes both unicellular & multicellular
organisms
C. Do have a true nucleus & membrane-bound
organelles
D. Organelles are internal structures in cell’s that
perform specific functions
E. Eukaryotes include plant cells, animal cells, fungi,
algae, & protists
Cytoplasm
• Location = inside cell
(outside the nucleus)
• Function = suspends
organelles
• Pro/Eu/both = both
• Plant/animal/both = both
Nucleus
• Location = near center of cell in
cytoplasm
• Function = controls the cell;
leader!
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Nuclear envelope
• Location = around nucleus
• Function = has pores through
which ribosomes & DNA pass
into cytoplasm
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Nucleolus
• Location = in nucleus
• Function = makes ribosomes
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Chromatin
• Location = in nucleus (or in cytoplasm in prokaryotes)
• Function = genetic code;
passes traits to offspring
• Pro/Eu/both = both
• Plant/animal/both =
both
Ribosome
• Location = in cytoplasm &
on rough ER
• Function = makes proteins
• Pro/Eu/both = both
• Plant/animal/both = both
Endoplasmic reticulum
• Location = in cytoplasm
(smooth ER: w/o ribosomes &
rough ER: with ribosomes)
• Function = transports substances
throughout cell & cellular
chemical reactions
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Golgi apparatus
• Location = in cytoplasm
• Function = modifies, sorts, and
packages proteins from ER
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Lysosome
• Location = in cytoplasm
• Function = digests substances
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Vacuole
• Location = in cytoplasm
• Function = temporary
storage
• Pro/Eu/both = both
• Plant/animal/both = both
(bigger in plant)
Mitochondria
• Location = in cytoplasm
• Function = produce energy in the
form of ATP
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Chloroplast
• Location = in cytoplasm
• Function = capture light energy
& produce food
(contains chlorophyll)
• Pro/Eu/both = Eukaryote
• Plant/animal/both = PLANT
Cytoskeleton
• Location = in cytoplasm
• Function = structure & support
Microtubules = thin, hollow proteins
Microfilaments = thin, solid proteins
• Pro/Eu/both = Eukaryotes
• Plant/animal/both = both
Centriole
• Location = in cytoplasm
• Function = organize cell division
• Pro/Eu/both = EU (animals and
most protists)
• Plant/animal/both = animal
Plasma/Cell membrane
• Location = surrounds cell
• Function = protection & selective
permeable (lets certain items in &
out)
• Pro/Eu/both = both
• Plant/animal/both = both
Cell wall
• Location = outside the cell
membrane
• Function = support &
protection
• Pro/Eu/both = both
• Plant/animal/both = PLANT
