| Term | Definition |
|---|
| Course focus knob | brings the specimen into view |
| fine focus knob | sharpen the image |
| Major difference between prokaryotic and eukaryotic cells | prokaryotic cells lack nuclei and membrane bounded organelles |
| plasma membrane | boundary that seperates the cell from its surroundings and regulates chemical composition of the cell |
| rigid outer framework surrounding the cell which gives definite shape and support | cell wall |
| nucleus | carries DNA and controls cell metabolism and division |
| choloroplast | carries the pigment cholorphyll involved in photosynthesis |
| mitochondrion | produces ATP through cellular respiration |
| vacuole | serves to store metabolic waste and gives the cell support by means of turgor pressure |
| golgi apparatus | active in the modification and transport of proteins |
| peroxisome | contains enzymes (as catalyses) which act in oxidative reactions and especially in the production and decomposition of hydrogen peroxide |
| lysosome | contains various hydrolytic enzymes |
| endoplasmic reticulum | functions in diverse metabolic processes, including synthesis of lipids, metabolism of carbs, detoxification of drugs and poisons and secretion of different proteins produced by ribosomes attached to its membranes |
| ribosome | site of protein synthesis |
| flagella and cilia | specialized in locomotion |
| hypotonic solution | the lower concentration of OAS, than the solution on the other side of the membrane |
| hypertonic solution | the higher concentration of OAS, than the solution on the other side of the membrane |
| the same concentration of OAS in the solution and the other side of the membrane | isotonic solution |
| plasmolysis | process of water moving out from the protoplast placed in the hypertonic solution |
| turgor pressure | pressure by protoplast on the cell wall owing to uptake of water |
