10 Cards in this Set
- Front
- Back
|
cell membrane structure and function |
-single lipid bilayer - controls what enters and leaves the cell-protection/suppourt |
|
|
Rough ER |
rough endoplasmic reticulum -consists of mostly flattened sacs (cisternae) -studded with ribosomes -continous with smooth er - makes modfies and ships proteins to the golgi complex - adds carbs to proteins to make glycoproteins |
|
|
Smooth ER |
-more tubes than flat sacs - no ribosomes continous with rough er -makes lipids (including steroids and phospholipids) -detoxifies alcohol and other drugs |
|
|
Golgi Complex |
stackes of flattened sacs (cisternae) no ribosomes - modifies, sorts and ships proteins to their final destinations |
|
|
Lysosomes |
small vesicle containing digestive enzymes - digests and removes damaged organelles(autogaphy) - fuses with food vacoule, digests contents and releses nutrients (phagocytosis) |
|
|
Mitochondria |
usually bean shaped surrounded by a double membrance inner membrane is highly folded makes ATP cellular respiration (burning of glucose) |
|
|
Nucleus |
largest organelle bound by double membrane continous with the RER controls protein synthesis and metabolism storage of genetic information |
|
|
Specify the characterics we associate with life |
1. Living things exchange materials 2. obtain enerfy from organic molecules 3. synthesize complex organic materials 4. reproduce 5. respond to stimuli |
|
|
Describe the chemical, cellular, tissue and organ system levels |
1. cells are the basic unit of life and they are mostly composed of chemical substances, organelles and membranes. The major chemicals are organic and inorganic molecules 2. in order to carry out functions cells are formed into groups called tissues. A tissue is a similar group of cells. 3. The tissues are then organized into organs and form and function composed of two or more tissues 4. organs then turn into organ systems which consists of a group of organs that interact to perform a general function. |
|
|
Vesicles |
are membrane bound sacs that may contain food particles. Other solids or liquids Vesicles function in storing, importing or exporting materials. |
