Question | Answer |
Cell | Basic unit of life |
Cell theory | Fundamental concept of biology that states- All living things are composed of cells, cells are the basic unit of structure and function in living things and new cells are produced from existing cells. |
Nucleus | A large membrane-enclosed structure that contains the cells genetic material in form of DNA. |
Eukaryote | Cells that contain nuclei. |
Prokaryote | Cells that do not contain nuclei. |
Organelle | Cells that act as if they are specialized organisms. |
Cytoplasm | The portion of the cell outside the nucleus. |
Nuclear envelope | The cooating around cell that allows material to move in and out of the cell. |
Chromatin | The granular material seen in nucleus. Consist of DNA bound to protein. |
Chromosomes | The granular material seen in a nucleus. |
Nucleolus | The small, dense region in a nuclei.Where ribosomes begins. |
Ribosomes | Small particles of RNA and protein found throughout the cytoplasm. Produces protein by following coded instructions that came from the nucleus. |
Endoplasmic Reticulum | The site where lipid components of the cell membrane are asssembled, along with proteins and other materials that are exported from the cell. |
Golgi Apparatus | The function of the golgi apparatus is to modify, sort, and package proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell. |
Lysosomes | Small organelles filled with enzymes.Break down lipids. |
Vacuoles | Sacklike structures that store materials such as water, salts, proteins, and carbs. |
Mitochondria | Organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use. |
Chloroplasts | Organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis. |
Cytoskeleton | Supporting structure that gives eukaryote cells their shape and internal organization. |
Centrioles | Located near the nucleus and organise cell division. Not found in plant cells. |
Cell Membrane | Sometimes called the plasma membrane because many cells in the body are in direct contact with the fluid portion of the blood-the plasma. |
Cell Wall | Strong supporting layer in a cell around the membrane. |
Lipid bilayer | The double layered sheet composition of nearly all cell membranes. |
Concentration | The mass solution in a given volume of sollution, or mass/volume. |
Diffusion | When particles move from a more concentrated area to a less conentrated area. |
Equilibrium | The concentration of a solute is the same througout a system it reaches equilbrium. |
Osmosis | The diffusion of water through a selectively permeable membrane. |
Isotonic | When solutions (water and sugar)will be same on both sides of membrane. Means "same strength" |
Hypertonic | The more concentrated sugar. "more strength" |
Hypotonic | |
