Biology 5 Flashcards
Cell membrane structure
Flexible fluid phospholipid bilayer. Contains embedded proteins
Cell membrane function
Controls what goes in and out of a Cell
Cell wall structure
Rigid structure made of cellulose (carbohydrate)
Cell wall function
Provides and maintains the shape of the cell and serves as a protective barrier.
Cytoplasm structure
Jelly-like fluid that fills the cell.
Cytoplasm function
Contains all the organelles (cell parts) and is a location for chemical reactions.
Mitochondria structure
Membrane structure that has a smooth outer membrane and a highly folded inner membrane.
Mitochondria function
Converts sugar to ATP so the cell can carry out its functions.
Lysosomes structure
Small, membrane-bound structure.
Lysosomes function
Contains enzymes necessary for intracellular digestion.
Vesicle structure
Membrane-bound structures that form from the cell membrane or Golgi Body.
Vesicle function
Transports molecules throughout the cell.
Golgi bodies structure
Stacks of membrane-bound vesicles.
Chloroplast structure
Double outer membrane and contains light-collecting parts.
Chloroplast function
Converts sunlight energy to sugar.
Golgi bodies function
Packages macromolecules (like proteins) and distributes them.
Endoplasmic reticulum structure
Membrane-bound vesicles and tubules that sometimes have ribosomes on them.
Endoplasmic reticulum function
Can assemble proteins or hormones.
Ribosomes structure
Two subunits made of RNA and proteins. Can be floating in cytoplasm or embedded in the ER.
Ribosomes function
Assembles amino acids to create proteins.
Nucleus structure
Membrane-enclosed structure that contains nuclear pores.
Nucleus function
Protects DNA, allows certain molecules in/out to “read” DNA code.
Cytoskeleton function
Maintains cell shape, moves cell parts, helps cells move
Centriole’s function
Organize cell division
