| Term | Definition |
|---|
| nucleus | have a true ......... and other membrane bound organelles |
| plasma membrane | controls movement in and out of cell, is differentially (selectively) permeable, can have microvilli to increase surface area |
| mitochondria | site of cellular respiration, transfer the energy in glucose to ATP. Have a highly folded inner membrane to increase surface area. |
| ribosomes | site of protein synthesis, made of protein and RNA |
| smooth endoplasmic reticulum | no ribosomes, site of steroid and lipid synthesis (vesicles carrying lipids are budded) |
| rough endoplasmic reticulum | ribosomes attached, packages and transports proteins to the golgi apparatus |
| golgi apparatus | modifies or repacks proteins or other substances e.g. lipids from the rER into vesicles to be transported out of cell or to another organelle |
| vesicles | transport materials between organelles and to and from the cell membrane by endocytosis and exocytosis |
| nucleus | controls and directs activities of the cell, produces ribosomes, contains chromosomes with genetic information |
| nuclear envolope | separates the nucleus from the cytoplasm and controls movement in and out of cell |
| nuclear pore | allows exchange of substances from the nucleoplasm and the cytoplasm |
| nucleolus | site of ribosome synthesis |
| lysosome | contain powerful enzymes that digest worn out cell parts or foreign particles |
| cilia | for absorption of gases to increase surface area |
