bio- organelles
Terms
undefined, object
copy deck
- smooth er
- doesnt have ribosomes on it makes less protein
- cytoplasm
- site of life functions. mostly water fluid. holds the organelles in place
- mitchondria
- powerhouse. produces energy. site of respiration. uses oxygen to break down gluclose to make energy
- nucleus
- holds dna. controls metabolism and reproduction.
- cell wall
- only in plant cells. ridged and surrounds cell membrane. made of cellulose(carbohydrate)
- 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.
- 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
- endoplasmic reticulum
- stores, modifies and ships protein and others
- centrioles
- cell division only in animal cells
- microtubules
- hollow tubes. made of protein
- cytosol
- part of cytoplasm
- 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.
- ribosomes
- site of protein synthesis.
- phospholipids
- polar head- hydropholic likes water. fatty acid- hydrophobic doesnt like water
- nuclear envelope
- surrounds the nucleus made of 2 phosolipid bilayers
- flagella
- is whip like. it assits in motion. made of microtubules
- eukaryotic cells
- cells that contain a nucleus.
- cillia
- hair like. it assits in motion.
- plant vacuole
- holds water
- animal vacuole
- holds food
- contratile vacuole
- pushes excess water out in animal cells
- cholorplast
- site of photosynthesis. contains chlorophyll- absobrs light
- cell theory exceptions
- 1. first cell. 2 virus 3. mitchondria and chloroplast. they have their own dna so they can reproduce on their own
- rough er
- has ribosomes on it and makes a lot of protein
- organelles
- inercellular bodies that have a specific function
- microfilament
- made of protein. assits in cyclosis
