Cell Biology - cell structure and function Flashcards
cell/plasma membrane structure
selectively permeable
both plants and animals
cell/plasma membrane function
lets select material in/out:
contains cell and keeps things in cell stable
cytoplasm structure
jelly-like liquid inside cells
both plants and animals
cytoplasm function
supports organelles floating in it
cytoskeleton structure
collection of fibers throughout cell
both plants and animals
cytoskeleton function
supports cell and organelle shape
allows movement between organelles
3 parts: microtubules, actin filaments, intermediate filaments
ribosomes structure
non-membrane bound organelles
both plants and animals
ribosomes function
protein syntehsis (enzymes, DNA coding, etc)
free or bound to rough ER
nucleus structure
nucleolus, nuclear envelope, chromatin (DNA)
both plants and animals
nucleus function
holds DNA; genetic info for making proteins and other molecs.
Endoplasmic Reticulum structure
rough (ribosomes)
or smooth (no ribosomes)
both plants and animals
ER function
processing of molecules (ex protein folding)
involved in transporting said molecs around
rough ER involved in protein producing/transporting via ribosomes
smooth ER involved in detoxification (liver), making some lipids
Vesicle structure
small sac filled with fluid
both plants and animals
Vesicle function
carries/transports in and out of cell
golgi apparatus structure
disconnected, flattened “stack of pancakes”
both plants and animals
