Cytoplasm Flashcards
Stabilizes cell shape; organization of organelles and inclusions
Intermediate filaments
Parallel bundles of filaments (actin)
Microfilaments
Fluid-like or gel-like matter
Cytosol
Dense ovoid granules or flocculent irregular bodies with lipid inclusions
Pigment
Organization and orientation of microtubules, cilia, and flagella
Centriole
UV protection or storage of undigested materials
Pigment
Store of carbohydrate
Glycogen
Energy store; used for biogenesis
Lipid (fat)
Concentration, packaging of secretory products; membrane recycling
Golgi complex
Round or elliptical membrane bound bodies
Peroxisome
Membrane-bound vacuoles with internal vesicles
Multi-vesicular body
Circular droplets, gra to black in electron micrographs
Lipid (fat)
Usualy a store of protein
Crystals
Needle; polygonal or triangular latticework
Crystals
Nine triplets of short microtubules arranged in a cylinder
Centriole
Long, hallow tubes of protein subunits (tubulin)
Microtubules
Bundles or networks of filaments (vimentin, keratin, desmin)
Intermediate filaments
Branching tubules or broad, flat, parallel, and concentric saccules
Smooth endoplasmic reticulum
Ovoid or elongated; inner folded membrane
Mitochondrion
Contains oxidative enzymes; lipid metabolism
Peroxisome
Myosin
Thick filaments
Contain hydrolytic enzymes for degrading many substances
Lysosome
Protein synthesis and segregation
Rough endoplasmic reticulum
Parallel stacks of saccules often in a U-shape
Golgi complex
Small electron-dense clumps or rosettes
Glycogen
Cell contraction, motility
Microfilaments
Cell shape; intracellular movement
Microtubules
A form of lysosome
Multi-vesicular body
Long, flattened saccules occasionally branched; surface ribosomes
Rough endoplasmic reticulum
Contains all the molecules for the cell’s metabolic functions
Cytosol
Steriod or fat synthesis; detoxification of drugs
Smooth endoplasmic reticulum
Oxidative phosphorylation, ATP production
Mitochondrion
Cell motility, contraction
Thick filaments
Ovoid or irregular-shaped organelle
Lysosome
