| Cell | The basic unit of structure and function of living things. |
| Microscopic | Too small to be seen without using a microscope. |
| Organism | Any living thing that mantains vital life processes |
| Cell Membrane | The thin covering that surrounds every cell. |
| Nucleus | The part of a cell that directs all of the cell's activities. |
| Cytoplasm | The jellylike material inside a cell between the cell membrane and the nucleus. |
| Protist | A single-celled organism with a nucleus and organelles |
| Organelles | Tiny parts inside cell, help keep cell alive and functioning. The organelles are specialized cell parts. |
| Cell Wall | An organelle that surrounds the plant cell and provides additional support. |
| Chloroplasts | Organelles in plant cells that help the plant make food. |
| Vacuoles | Small spaces in a cell that store materials until they are used or released.The vacuoles store water, nutrients, or waste material. |
| Mitochondria | Organelles that provide energy for the cell. They are suspended in the cytoplasm, "power houses"of the cell. |
| Chromosomes | Tiny, threadlike structures that contains an individual's genetic code. They contain information about the characteristics of the cell. |
| Diatoms | A very common type of phytoplankton, a type af algae.Most diatoms are found in water,such as oceans and rivers, but they are also found in soil |
| Diatoms | They are a very important comnponent of oceanic food chains. |
| Diatom's cell structure | Takes silica from the enviroment and uses it to construct its cell membrane. |
| Bacteria | Single cell organism. Not all of theses cells are harmful, some are germs. |
| Protozoa | Simple organism, animal-like protist. They get food by "eating" other small organisms, such as algae and bacteria. |
