Organelles Flashcards
(30 cards)
Channels for exchanging materials
Gap junctions (cell junction)
Prevents fluid movement between cells
Tight junctions (cell junction)
Support and protection
Cell wall
Controls the cytoskeleton for reproduction
Centrioles
Area of cytoskeleton that assists in reproduction
Centrosomes
Site of photosynthesis
Chloroplasts (plastids)
Propel a cell or move fluid
Cilia
Water area of a cell with dissolved ions and molecules
Cytoplasm/ cytosol
Hold cells together into tissues
Desmosomes (cell junction)
Anchor cell structures
Intermediate filaments (cytoskeleton)
Stabilize shape
Microfilaments (cytoskeleton)
Rigid structure and moves organelles
Microtubules (Cytoskeleton)
Hereditary information
DNA (chromatin)
Hold cells together and allows for the exchange of materials between cells
Extracellular matrix
Long tails that ouch or pull cells
Flagella
Processes and packages proteins (sort proteins), prepares polysaccharides for cell wall, gets materials out of the cell
Golgi apparatus/ Golgi body
Digestion; breakdown of macromolecules; breakdown of organelles and extracellular components, need these to get into the cell
Lysosome
Breakdown of energy- rich molecules into chemical energy
Mitochondrion
2 lipid bilayers that cover the nucleus
Nuclear envelope
Opening in envelope that allows materials to move through, ex: RNA and ribosomes
Nuclear pore
Assembles ribosomes
Nucleolus
The site of most cellular DNA; holds DNA replication and RNA transcription
Nucleus
Accumulates toxic byproducts of chemical reactions and breaks them down
Peroxisome
Enclose and separates; controls exchange of materials
Plasma (cell) membrane
