|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
