| Term | Definition |
|---|---|
| CELL THEORY | Cell are the basic unit of life. All living things are made up of cells. All cells come from pre-existing cells. |
| PROKARYOTE | Very simple, unicellular cells " PRO=NO NUCLEUS" ONLY BACTERIA can be prokaryotes |
| EUKARYOTE | "EU = DO have a NUCLEUS"- complex cell found in all other organisms. Protists, Plants, Fungi and Animals. Has many organelles. |
| NUCLEUS | Control Center/ Contains DNA on chromosomes. |
| CELL WALL | Gives structure & support Ex. Plant and Bacteria |
| CHLOROPLAST | Converts Light energy to Chemical energy ( glucose) in plants. |
| RIBOSOME | Makes proteins ( put together amino acids) |
| ENDOPLASMIC RETICULUM | Transports cell materials around the cell. Rough ER has ribosomes on it and transports proteins Smooth ER has NO ribosomes & transports lipids |
| MITOCHONDRIA | Powerhouse of cell, ATP of Energy |
| CYTOPLASM | Jelly like substance, supports organelles |
| FLAGELLA | Whip like tail, movement , Ex. sperm |
| ORGANELLE | Mini- organ/ carry out cell functions. |
| CELL MEMBRANE | Controls what comes in and out of the cell. |
| NUCLEOLUS | Inside Nucleus, Makes ribosomes |
| GOLGI APPARATUS | Processes packages, ships out cell products |
| CHLOROPHYLL | Pigment that absorbs sunlight. |
| VACUOLE | Cell Storage, larger in plants for water |
| LYSOSOME | Digestion of cell waste, scrap yard |
| CILIA | Hair like projection, movement ex. Paramecium |
| Theodor Schwann | All animals are made of cells Hint: "Swan is an animal" |
| Matthias Schleiden | All Plants are made of cells Hint: "Sliding in the grass" |
| Robert Hooke | First to discover cells by looking at cork and name them cells Hint: Hooke almost rhymes with Cork |
| Rudolf Virchow | All Cells come from pre-existing cells. |
| Anton van Leeuwenhoek | First to look at living cells. HINT: van Leeuwenhoek = van LIVING hook. |
