Cell Function Flashcards
Function
Cell men brain
Forms the boundary between the inside and outside of the membbrain
Cell men brain
Phospholipid by layer embedded with proteins
Nucleus structure
Surrounded by a nuclear membrane enclosing genetic material (DNA )
Founction nucleus
Contains most of the cell genetic me trail
Ribosomes function
Synthesis of polypeptides (makes proteins )
Ribosome stricter
Made up of ribsomal RNA
Mitochondria structure
Bean shaped bounded by a dobel membbrain the iner layer is extensive folded to form partitions called cristae. Fuid filled space called matrix
Golgi apparatus function
Modifications of proteins and lipids received from the er
Sorting packing and storage of proteins and lipids
Transport of these materials in vesicles through the cell
Rough er structure
A system of membranous tubules studded with ribosomes
Rough er function
Sun
Smothe er fonction
Synthesis of lipids including oils phospholipids and steroids
Carbohydrate metabolism
Transports metaral through the cell
Nucleons structure
Dence area in nucleus
Centrioles structure
Found as a pair
Each one is composed of nine sets of triplets microtubes arranged in a ring
Vacuoles and vesicles structure
Vacuoles and vesicles boath membbrain bound sacs but vacuoles are larger
Vacuoles and vesicles fount ions
Food vacuoles
Contractile vacuole
Chloroplast structure
Two outer men brains are separated by a narrow inter membbrain space
Inside the cloroplaste are stakes of flattened sacs of thylakoids witch are stacked together as grana
Fluid filled space called the stoma
Cell wall fionction
Protects the cell
Maintains cell shape
Prevents to much water getting in the cell
Lysosomes function
Digests fats proteins and old cells they break things down then reuses cells
Lysomes structure
Single membrane bound sac of hydrolytic enzymes
