Life Science
| Term | Definition |
|---|---|
| Lysosomes | recycles worn out cell parts |
| Centrioles | used for cell division |
| Small Vacuole | holds nutrients and water; aids in digestion |
| Endoplasmic Reticulum (ER) | produces and transports proteins |
| Ribosomes | assists the ER in producing and transporting proteins |
| Mitochondria | converts food into energy |
| Nucleus | holds all genetic material including DNA; serves as “the brain” to the cell |
| Cytoplasm | the fluid that holds all the organelles in place |
| Cell Membrane | forms a boundary around the cell; allows food and water to enter and waste to exit |
| Chloroplast | converts sunlight into food |
| Large Vacuole | holds nutrients and water; aids in digestion |
| Cell Wall | provides support and security for the plant |
| Plant cells | are rectangular |
| Plants are | immobile so they need to have a large vacuole to hold a large amount of water and a cell wall to help with protection |
| Plants have | to make their own food therefore they must have chloroplasts |
| Animal cells | are circular |
| Animals are | mobile so they only need a small vacuole |
| Animals have | the ability to heal so they need centrioles to produce new cells when existing ones are lost or damaged. They also need lysosomes to help get rid of damaged cells or cell parts |
| Biological objects in order from least complex to most complex | Organelle -> cell -> tissue -> organ -> organ system -> multicellular organism |
| Multicellular and Single-celled Organisms Similarities | They both have to get the job done in order to stay alive |
| Multicellular and Single-celled Organisms Differences | Single-celled organisms are like golfers. One cell is in charge of doing all of the jobs necessary to keep the organism alive |
| Multicellular organisms | are like a football team. Many cells do specific jobs and work together to keep the organism alive |
| Diffusion | the movement of particles from an area of higher concentration to an area of lower concentration |
| Osmosis | the diffusion of water across the cell membrane |
| DNA | material in the cell's nucleus that stores coded information about how an organism will grow and develop |
| Chromosome | coiled structure in a cell's nucleus that carries information controlling the cell's activities |
| Mitosis | a process in which a cell nucleus divides |
