bio- organelles

Terms

undefined, object
copy deck
endoplasmic reticulum
stores, modifies and ships protein and others
cell theory
1. cells are the smallest unit of function 2. cells are the smalles unit of structure 3. every cell comes from a pre-existing cell.
cell wall
only in plant cells. ridged and surrounds cell membrane. made of cellulose(carbohydrate)
rough er
has ribosomes on it and makes a lot of protein
cytoplasm
site of life functions. mostly water fluid. holds the organelles in place
contratile vacuole
pushes excess water out in animal cells
cell membrane
surrounds the cell. controls what goes in and out of cell. made of phospholipids maintains homeostasis
prokaryotic cells
no nucleus. dna is in the cytoplasm.
ribosomes
site of protein synthesis.
organelles
inercellular bodies that have a specific function
centrioles
cell division only in animal cells
nuclear envelope
surrounds the nucleus made of 2 phosolipid bilayers
nucleus
holds dna. controls metabolism and reproduction.
flagella
is whip like. it assits in motion. made of microtubules
smooth er
doesnt have ribosomes on it makes less protein
microfilament
made of protein. assits in cyclosis
plant vacuole
holds water
eukaryotic cells
cells that contain a nucleus.
microtubules
hollow tubes. made of protein
phospholipids
polar head- hydropholic likes water. fatty acid- hydrophobic doesnt like water
cillia
hair like. it assits in motion.
animal vacuole
holds food
cytosol
part of cytoplasm
golgi bodies
transports and modifies chemical that goes in and out of cell. removes waste
cytoskeleton
made of microtubules, and microfilaments
lysosome
only in animal cells stores strong digestive enzyme. destroys cells that no longer function properly
cell theory exceptions
1. first cell. 2 virus 3. mitchondria and chloroplast. they have their own dna so they can reproduce on their own
mitchondria
powerhouse. produces energy. site of respiration. uses oxygen to break down gluclose to make energy
cholorplast
site of photosynthesis. contains chlorophyll- absobrs light
