cells
| Term | Definition |
|---|---|
| Six Characteristics of living things | * maintain homeostasis *respond * require energy *grow and develop *can reproduce *have one or more cells |
| Homeostasis | Maintain a stable internal invironment |
| Cell Theory | 1)All organisoms are made of one or more cells 2)a cell is the smallest living thing 3)All new cells come from pre-existings cells |
| The four things all cells have | *DNA *CELL MEMBRANE *CYTOPLASM *RIBOSOMES |
| Selectively Permeable | Some things can go through and some things can go out. |
| The Cell Membrane allows this in? | nutrients-water-O2 |
| Diffusion | The movement of particles from an area of low concentration to high concentration |
| cell membrane | Selectively Permeable |
| Ribosomes | It provides protien |
| Golgi body | Packages molecules that are ready to be sent out |
| Lysosomes | They clean the cell they are like the janitors |
| Cell Wall | It protects the cell |
| mitochondria | Transforms energy that's in food into energy the cell can use |
| central vacuole | stores food, water, and waste products |
| The Rough ER | this is where proteins are made. It transports things through the cell |
| The Smooth ER | It detoxifies harmful substances that enter the cell. |
| chloroplast | Demonstrates photosynthesis |
| cytoplasm | Contains nutrients and holds the organelles in place |
| nucleus | Gives instructions to the cell |
| Prokaryotic Cell | less complex,smaller, bacteria is made of this cell, first living organism on the planet. |
| Eukaryotic Cell | More complex, Animals and plant's are made of this, has organelles,DNA is found in the nucleus. |
| This transports materials within and without the cell | water |
| The three unique things about plant cells are this | These are the three things that are unique about plant cells, they have chloroplast, they have a central vacuole, and they have a cell wall. |
