Functions :
- gives shape to cells lacking a cell wall
-
- movement of organelles within a cell
-
-
-
-
-
-
- attached to ER are secreted for use outside of the cell
- proteins formed at cytoplasmic ribosomes are used inside the cell
- surrounded by two membranes; inner membrane is arranged in a series of folds called cristae
-
-
-
- protein synthesis with ribosomes attached
- stacks of membrous saccules
- processing, packing and distributing of proteins and lipids
-
-
- membranous sacks/ vesicles containing digestive enzymes
-
- " suicide cells" destroys bad cells by tacking it in and self-destructing
gives only plant cells extra protection, structure, support, and surrounds cell
-
-
-
- digest materials that enter the endocytosis
- composed of rRna and proteins: 2 subunits (60S and 40S)
- workbench for protein synthesis
- consists of tubulin microtubules, actin microfillaments, polypeptide intermediate fillaments.
- parallel membranous tubules and flattened sacs surrounding the nucleus and runs throughout the cytoplasm
