Cells
| Question | Answer |
|---|---|
| What does the cell theory state? | It states that the cell is the basic unit of life, All organisms are composed of one or more cells, and all cells come from other living cells. |
| Living things have five main characteristics, what are they? | Respond to their environment, need energy, Grow, Get rid of wastes and Reproduce. |
| Nucleus | The organelle that controls all the activities within the cell. |
| Vacuole | Temporary storage compartments in cells. Sometimes used to store wastes. |
| Mitochondria | The energy producers in the cell that carryout cellular respiration to produce energy for the cell. |
| Cytoplasm | A jelly-like substance within a cell, containing organelles, water and other life-supporting materials. |
| Endoplasmic Recticulum | A network of membrane covered channels that transport materials. |
| Chloroplasts | parts of plant cells that trap energy from the sun and change it into chemical energy that plants use. |
| Ribosomes | Cell parts that assemble proteins |
| Golgi Body | A structure in cells that sorts proteins and packs them into vesicles. |
| Cell Wall | A tough, rigid structure that surrounds and protects a plant cell and gives the cell its rectangular box-like shape. |
| Cell Membrane | A thin protective covering that separates interior of a cell from its surroundings; also controls the movement of particles into and out of the cell. |
| Cellular Respiration | A process in which the chemical energy taken in through food is changes into energy that cells use to carry out their activities. |
| Metabolism | The total of all chemical reactions that take place in the cells. |
| Viruses | Tiny non-living particles capable of reproducing only when they are inside a host cell; They have no nucleus or organelles and are usually disease causing. |
| What are the two groups of cells? | Prokaryotic and Eukaryotic cells. |
| Celluar Respiration | The process that produces energy for the cell. |
| Prokaryotic Cells | A type of cell whose organelles are not surrounded by membranes. |
| Eukaryotic Cells | A type of cell whose organelles are surrounded by membranes. |
| Bacteria | Any of various groups of single-celled micro-organisms, some of which can cause disease. |
| Vesicles | Membrane - wrapped structures that carry proteins, nutrients, and water into, out of and around the inside of a cell. |
| Organelle | A cell part in which functions are carried out to ensure the cell's survival. |
| Selectively Permeable membrane | A membrane that allows some materials to pass through it but keep other materials out. |
| The word "microbe" comes from a Greek word meaning | Small Life |
| Stimulus | Anything that causes a living thing to respond |
| what two things are in plant cells that are not in animal cells. | Chloroplasts, and Cell Wall |
| Host | Organism that a parasite or virus lives on or in. |
| Lysosome | A cell structure containing digestive chemicals that function to break down food particles, cell wastes and worn- out cell parts. |
