Cell Organelles
Cell Organelles Structure and Functions
| Question | Answer |
|---|---|
| The structural and functional unit of all living organisms, and is sometimes called the "building block of life." | Cell |
| Structures that have a specific jobs within a cell | Organelles |
| Gatekeeper of the cell, regulates the flow of materials in and out of the cell | Cell membrane |
| Found in plants, fungi and bacteria that serves as extra support and protection | Cell wall |
| Provides a medium for chemical reactions to take place. | Cytoplasm |
| Controls the normal activities of the cell and contains the DNA in chromosomes. | Nucleus |
| Protein factories for cells | Ribosomes |
| Contains RNA and act as a messenger carrying instructions from DNA for controlling the synthesis of proteins. | Nucleolus |
| Threadlike structure of nucleic acids and protein found in the nucleus carrying genetic information in the form of genes. | Chromosomes |
| Lipid synthesis is made | Smooth Endoplasmic Reticulum |
| A network of flattened membrane sacs that helps complete the proteins after ribosome builds them and moves material around in cell. | Endoplasmic Reticulum |
| Modify, sort, & package molecules from ER for storage or transport out of cell. | Golgi Bodies |
| Stores and move materials between cell organelles, as well as to and from the cell surface. | Vesicles |
| Found only in plants that is for storage of needed materials like water, food molecules, salts inorganic ions and enzymes. | Vacoules |
| Contain hydrolytic enzymes that breaks down food, bacteria, and worn out cell parts for cells. | Lysosomes |
| Contains oxidase enzymes for the breakdown of fatty acid molecules | Peroxisomes |
| “Powerhouse” of the cell that generates cellular energy (ATP) | Mitochondria |
| Use energy from sunlight to make own food (glucose) | Chloroplasts |
| Flexible network of long threads of fibers that can crisscross the entire cell providing sturdy mechanical support | Cytoskeleton |
| A type of cytoskeleton that is stiff hollow thick tubes that will form spindle fibers to pull the chromosomes apart during the cell division. | Microtubules |
| A type of cytoskeleton that are generally strong and rope like that gives the cell tensile strength and the ability to stretch without breaking apart. | Intermediate filaments |
| A type of cytoskeleton that provide protective meshwork under plasma membrane and is important component in muscle contraction. | Microfilaments |
| An area in the cell where microtubules are produced (MTOC) that help coordinate cell division. | Centrosome |
| Occur in pairs, only in animal cells that helps in cell division and cell organization. | Centriole |
| Found in the small intestine that aids in absorbing the nutrients. | Microvilli |
| Function in moving cells, in moving fluids, or in small particles across the cell surface ex. interior of the lungs | Cilia |
| Found in sperm cells that aids for locomotion | Flagella |
| A layer mix of proteins and polysaccharides (glycoproteins) secreted by the cells that provides structural and biochemical support to the surrounding cells. | Extracellular Matrix |
| Important in sharing of water, nutrients and chemical messages among plant cells. | Plasmodesmata |
| Cells are joined together to form leakproof sheet example in bladder to prevent urine from leaking out. | Tight Junctions |
| Act like screws together with cytoskeletal fibers to form strong sheets. | Anchoring junctions |
| Gap junctions play a similar role to that of plasmodesmata, as both allow small molecules to flow between neighboring cells. | Gap junctions |
