|---|---|
| Cell Membrane |  A thin double layer of lipids enclosing the cytoplasm of a cell. All cells have a _________. |
| Cell | Basic structural unit of all organisms. |
| Chloroplast | The organelle in which plant cells perform photosynthesis. |
| Endoplasmic Reticulum(ER) | A eukaryotic organelle that forms a network of tubules and vesicles within the cells. |
| DNA | Nucleic acid that contains genetic instructions. |
| Organelle | Structure inside a cell that had specialized functions. |
| Cell Wall | A tough, flexible layer that surrounds some types of cells. |
| Homeostasis | A living organisms ability to adjust its internal environment to maintain a stable equilibrium. |
| Organ System | A group of organs that work together to perform a certain task. |
| Tissue | Part of an organism consisting of a similar group of cells with similar functions. |
| Prokaryote | An organism with cells that don't have nuclei. |
| Multicellular | Composed of one or more cells. |
| Unicellular | Consisting of a single cell. |
| Eukaryote | A cell with a nucleus; this includes all animal cells. |
| Nucleus | A part of a cell that is membrane enclosed found in eukaryotic cells. They control everything in a cell, are located in the center of the cell, and have the instructions to make proteins. |
| Organ | A fully differentiated structural unit. |
| Cytoplasm | The contents of a cell, excluding the nucleus. Contains gel-like fluid, water, salt, and organelles. |
| Mitochondria | A membrane enclosed organelle found in most eukaryotic cells; they contain enzymes responsible for producing energy. |
| Golgi Apparatus | An organelle that looks like a stack of pancakes; found in most eukaryotic cells. It packages proteins and carbs into vesicles to export from cell. |
| Vacuole | A tiny cavity filled with jelly-like fluid found in the cytoplasm of a cell. |
| Lysosome | An organelle found in all animal cells. |
| Cytoskeleton | A network of protein filaments in a eukaryotic cell that gives the cell its shape & internal organization. It's also involved in movement. |
| Centrioles | Structure in an animal cell that helps organize cell division. |
| Ribosome | Organelle consisting of RNA and protein found throughout the cytoplasm in a cell. |
