Chapter 3- Organelles Flashcards
Nucleus
Control center of cell, Eukaryotic
Ribosomes
Make proteins using instructions from DNA, in all cells
Cytoplasm
Holds structures in place within cell, in all cells
Cell membrane
Regulates what enters and leaves cell, in all cells
Nucleolus
Where building blocks of ribosomes made, Eukaryotic
Nuclear envelope
Allows materials in and out of the nucleus, Eukaryotic
Smooth ER
Synthesizes lipids, Eukaryotic
Rough ER
“Quality control” of cells (modifies proteins), holds ribosomes, in all cells
Vacuole
Stores various substances, eukaryotic
Golgi apparatus
Fishes, sorts, ships protein, Eukaryotic
Cytoskeleton, what is it made of?
Helps support, movement, Eukaryotic, microfilaments, intermediate filaments, microtubules
Chloroplast
Site of photosynthesis, plant only
Peroxisome
Breaks down fatty acids, eukaryotic
Mitochondria
Site of cellular respiration, eukaryotic
Cell wall
Keeps cell for bursting, plant + prokaryotic
Lysosome
Digests food particles, destroy + rececye damaged organelles, animal only
Tight junctions
Very tight, no leaking, digestive tract
Anchoring junctions
Rivet cells with cytoskeleton fibers forming sheet, allows stretching, skin
Gap junctions
Channels, allow molecules to flow from one cell to next, heart muscle contractions
Plasmodesmada
Channels in cell walls, membranes of plant cells
Cilia
Short and numetoys, beat together, throat
Chromatin vs chromosome
Chromatin- Uncoiled DNA, thread-like
Chromosome- Coiled DNA, 46 in nucleus of all cells
Cytolysis vs plasmplysis
Cytolysis-Animal cells bursting
Plasmolysis-Plant cells bursting
