cells and organelles Flashcards
PROkaryote
NO nucleus or cell membrane
EUkaryote
TRUE nucleus and cell membrane
organelle
“little organ”, a specific job within a cell
cytoplasm
fills and protects the cell; B
nucleolus
produce and assemble ribosomes within the cell; B
nucleus
cell’s control center, DNA is here; B
nuclear envelope
separates the nucleus from the rest of the cell; B
ribosomes
makes proteins; B
rough endoplasmic reticulum
synthesize proteins, transport things around cells, ribosomes; B
smooth endoplasmic reticulum
synthesize lipids, transport things around cells, no ribosomes; B
golgi apparatus
packages and ships; B
vacuoles
storage; B
mitochondria
food molecules break down which convert into energy for the cell’s survival; B
lysosomes
break down excess or worn-out cell parts; A
cytoskeleton
helps cells maintain shape; B
microfilaments
Supports the cell, not hollow, cell movement; B
microtubules
Shape of the cell, hollow, cell division; B
chloroplasts
produce energy through photosynthesis; P
cell wall
provides strength and protection against mechanical stress; P
cell membrane
regulates the transport of materials entering and exiting the cell; B
Hypotonic
Excess O2, minimal solute
Hypertonic
Lack of O2, excess solute
Isotonic
Equal
Solute
Particles dissolved in the solution
