Science Cell Theory
| Question | Answer |
|---|---|
| Scientist who identified cells | Robert Hooke |
| Scientist who discovered nucleus and protoplasm | Robert Brown |
| Plants are made up of cells | Matthias schleiden |
| Animals are made up of cells | Theodore schwann |
| Cells divide to form new cells | Rudolf virchow |
| Major cell parts | Cytoplasm, nucleus, cell membrane |
| are made up of protein scattered through a double layer of lipid | Cell mambrane |
| Cell coats in animal cells formed by carbon bonded | Protein(glycoprotein) and lipid (glycolipid) |
| Help cells respond to the environment | Cell membrane |
| Regulates movements of materials in and out of the cell | Cell membrane |
| Channel, carrier, recognition, receptors, and enzymatic | Cell membrane |
| Non living part of plant cell | Cell wall |
| Made of cellulose fibrils, pectin and lignin | Cell wall |
| Soft plant is made up of | Middle lamella and primary walls |
| In harder plants, it is made up of | Middle lamella, primary walls and secondary walls |
| Provides cell protection and shape maintenance | Cell wall |
| Allows a particular molecular cross the cell membrane freely as it enters/exits the cell | Channel protein |
| Example of channel protein that is inherited disorder caused by a faulty chloride channel. | Cystic fibrosis |
| Selectively interacts with a specific molecule so that the can cross the cell membrane | Carrier protein |
| Transport sodium ions and and potassium ions that requires ATP energy. | Carrier protein |
| Inability to use Na- K transport has been the cause of... | Obesity |
| Identifies the cell | Cell recognition protein |
| The MHC (Major Histocompatibility complex) glycoprotein are different from each person so organ transplant is hard to achieve | Cell recognition protein |
| Shaped to make a specific molecule bind to it | Receptor protein |
| Pygmies are short because they do not have enough | Receptor protein |
| Catalyzes a specific reaction | Enzymatic protein |
| Example of enzymatic protein involved in ATP metabolism | Adenylate cyclase |
| The brain of the cell | Nucleus |
| Controls all cellular activities | Nucleus |
| Chromosomes made up of RNA and DNA; for genetic info | Chromatin Material |
| Made of proteins, enzymes for RNA synthesis | Nucleolus |
| Thick, protein rich protoplasm in the nucleus | Nucleoplasm |
| Thin double layered, encloses the nucleus to permit materials to pass in and out | Nuclear membrane |
| Maintains nuclear environment different from the rest of the cell | Nuclear membrane |
| Fluid protection of the cell that hold various organelles | Cytoplasm |
| Transport system of the cell | Endoplasmic reticulum |
| Type of ER that has ribosomes for protein production and transport | Rough ER |
| Type of ER that contains many enzymes necessary for cell metabolism | Smooth ER |
| Series of closely stalked, flattened sacs | Golgi Apparatus |
| Pack substances in vesicles that are secreted from the cell | Golgi Apparatus |
| Site for protein synthesis | Ribosomes |
| Largest organelle | Mitochondria |
| Powerhouse of the cell | Mitochondria |
| Contains enzymes for digestion of food, injured dead cells | Lysosomes |
| Helpful in destroying bacteria | Lysosomes |
| Used for food, water, waste storage | Vacuole |
| Animal cells storage | Vesicles |
| Storage of unicellular organisms | Contractile vacuole |
| Contains food materials | Plastids |
| White colorless plastids common in seeds which stores oil, protein and starch | Leucoplast |
| Contains different pigmentations (plastids) | Chromoplast |
| With chlorophyll; plays important role in photosynthesis (plastids) | Chloroplast |
| Filamentous proteins that anchor organelles | Cytoskeleton |
| Thin fibers in cytoplasm - involve in the shape change (cytoskeleton) | Microfilaments |
| Thin hollow cylinders that maintain the shape and channel movements of substances in cells | Microtubules ( cytoskeleton) |
| Cell division; 9+0 pattern; involved in cell reproduction | Centrioles |
| Has 9+2 pattern of microtubules necessary for cell movement | Cilia and flagella |
