Colleen Cell
Structure of typical cell animal
Question | Answer |
---|---|
cell membrane | Contains cellular material and transports material between the inside and outside of the cell |
atom | Submicroscopic particles that make up all substance |
molecule | Arranged in specific patterns and structures |
cell | Human organism the basic unit of structure and function |
Protoplasm | All living matter is composed of a colorless, jelly-like substance |
4 ways cells differ from one another | Size, shape, structure and function |
4 principal parts of a cell | cytoplasm, centrosome, nucleus, and cell membrane |
Centrosome | DIVIDES and moves to opposite poles of the cell during mitosis |
Chromatin | Fibers of protein and DNA that contain the genes |
Endoplasmic reticulum | Produce lipids or proteins for cell utilization and TRANSPORT |
Golgi apparatus | Synthesizes carbohydrates and HOLDs protein for secreations |
Lysosome | DIGEST proteins, carbohydrates and other foreign substances that enter the cell. (filet) |
Mitochondria | Converts and releases ENERGY for cell operation (ribeye) |
Nuclear membrane | Controls passage of substances between the nucleus and cytoplasm |
Nucleolus | Forms Ribosomes |
Nucleus | SUPERVISES all cell activity |
Ribosome | Composed of RNA and protein molecules that SYNTHESIZE proteins (blackhead in reticulum) |
Vacuole | Involved in the RAPID EJECTION of substances (pimple) |
Cellular Metabolism | Chemical reactions within a cell that transform food into nutrients used for cell growth and operation |
Anabolism and Catabolism | 2 phases of Metabolism |
Anabolism | The process of BUILDING UP larger molecules from smaller ones |
Catabolism | The process of BREAKING DOWN larger substances or molecules into smaller ones |
Enzymes | Protein substance that act as organic catalysts to initiate, accelerate, or control specific chemical reactions in the metabolic process |
Order for the level of complexity of the human organism | Organism, Organ System, Organ, Tissue, Cell, Organelles, Molecules, Atoms |
Mitosis | A form of cell dividsion |
Metabolism | The complex chemical and physical process that takes place in living organism whereby the cells are nourished and carry out their activities |
Digestive process | Carbohydrates are broken down into simple sugars (glucose) fats are split into fatty acids and proteins are converted into amino acids. |
