Cell Vocabulary
| Term | Definition |
|---|---|
| Anton van Laauwenhoek | Identified singled-celled organisms called "animalcules" which we now know as protists |
| Biogenesis | The idea that life comes from life |
| Cell | The smallest unit of a living thing |
| Cell Membrane | The phospholipid bilayer of the cell that controls what comes in and out of the cell |
| Cell Theory | All living things are made of cells. Cells come from preexisting cells. Cells are the most basic unit of life. |
| Cell Wall | The layer in plants and some other organisms that provide structure and support for the cell. |
| Chloroplast | Organelle in autotrophs that goes through photosynthesis to make glucose(food) for the cell. |
| Chromosomes | Long threads of DNA |
| Eukaryotes | A cell that has a nucleus and other membrane bound organelles |
| Flagella | Whip like structure outside of the cell that aids in movement of the cell. |
| Fluid Mosaic Model | The model that describes the arrangement of molecules that make the cell membrane |
| Golgi Apparatus | Stack of flat structures containing enzymes that process, sort, and deliver proteins |
| Lysosomes | An organelle that contain enzymes that break down materials the cell does not need |
| Matthias Schleiden | Stated all plants are made of cells |
| Mitochondria | The organelle that undergo cellular respiration to make energy for the cell |
| Nucleolus | Where ribosomes are made |
| Nucleus | The store house from most of the cell's genetic material (DNA) |
| Phospholipid Bilayer | The double layer of the cell membrane |
| Prokaryotes | A cell without a nucleus and other membrane bound membranes |
| Ribosomes | Organelle that links amino acids to form proteins |
| Robert Hooke | First person to see cells |
| Endoplasmic Reticulum | Transport proteins to the needed area of the cell (rough ER have ribosomes attached) |
| Rudolf Virchow | Stated all cells come from preexisting cells |
| Semipermeable Membrane | A membrane that selects what comes in and what goes out |
| Spontaneous Generation | The idea that life can be made from nonliving things |
| Theodor Schwann | Stated all animals are made of cells and all living things are made of cells |
| Vacuole | The storage area of the cell, tends to be much larger in plant cells |
| Diffusion | Movement of gas or liquid from an area of high concentration to low concentration without energy |
| Active Transport | A type of transport that requires energy to move molecules from a low concentration to a high concentration |
| Concentration Gradient | The difference in concentration of a substance from one area to another |
| Flaccid | Limp |
| Facilitated Diffusion | A type of diffusion that use a protein channel |
| Exocytosis | The outtake of liquids or small molecules of the cell by the fusion of a vesicle to the cell membrane |
| Homeostasis | Maintaining a stable internal environment no matter what is happening outside |
| Hydrophilic | Water loving |
| Hydrophobic | Water fearing |
| Hypertonic | A solution that has a higher concentration of dissolved particles compared with another solution |
| Hypotonic | A solution that has a lower concentration of dissolved particles compared with another solution |
| Isotonic | A solution that has an equal concentration of dissolved particles compared with another solution |
| Osmosis | The diffusion of water from a high concentration to a low concentration |
| Passive | Movement of molecules across the cell membrane without the use of energy |
| Plasmolysis | Shrinking of the cytoplasm due to excess water loss |
| Transport Protein | A protein in the cell membrane that aids in difusoin |
| Endocytosis | Intake of liquids or small molecules into the cell by folding the cell membrane around the substance |
| Turgor Pressure | Pressure placed by bringing water into a cell |
