Organelles
-
Golgi Apparatus
FUNCTION: segregates proteins for cell secretion, packages, modifies, inclusion in lysosomes & into the plasma membrane
-
Peroxisomes
FUNCTION: enzymes that detoxify toxic substances! most important is catalase-breaks down hydrogen peroxide
Microfilaments
FUNCTION: muscle contraction & other intracellular movements, help form the cytoskeleton
Smooth ER
FUNCTION: lipid & steroid hormone synthesis, lipid metabolism, drug detox
Intermediate Filaments
FUNCTION: resist tension forces that are taking place on the cell, stable cytoskeletal elements
Microtubles
FUNCTION: they support the cell & give it its shape, form centrioles, take part in cellular movements & intracellular
Rough ER
FUNCTION: makes proteins that are secreted from the cell, makes the cells membranes!
Centrioles
FUNCTION: organize microtubule network during mitosis to form spindle &asters. they also form the bases of cilia & flagella
-
-
Endocytosis
Phagocytosis
eats other cells! like bacteria, viruses
Pinocytosis
cell drinking!-absorbs extracellular fluids, unselective!
-
Cell Cycle
Interphase: cell growth, DNA synthesis
-
-
-
-
Mitosis
2 Chromosomes, identical DNA of daughter cells with individual nucleus
