Lesson 2 Cells
| Term | Definition |
|---|---|
| Cell membrane | Controls what substances come into and out of the of a cell. |
| Nucleus | The cells control center directing all of the cells activities. |
| Organelle | Carry out specific functions in the cell |
| Mitochondria | Are known as the “power houses” of the cell because they convert energy in food molecules to energy the cell can use to carry out it’s functions. |
| Cytoplasm | A gel like fluid that moves structures throughout the cell. |
| Ribosomes | Function as factories to produce proteins |
| Endoplasmic reticulum | Passageways carry proteins and other materials from one part of the cell to another. |
| Golgi apparatus | Bodies receives proteins, and other newly formed and materials from the Endo plasmic, reticulum, package them, and distribute them to other parts of the cell. |
| Vacuole | Exactly like organelle that stores, water, food, and other materials |
| Lysosome | Are small, round structures containing chemicals that break down certain materials in the cells. |
| Multicellular | Organisms that are composed of many cells. |
| Unicellular | Single-celled organisms. |
| Organ | Is made of different kinds of tissues that function together. |
| Organ system | A group of organs that function together. |
| Specialized Cells | Specialized to perform specific functions. |
| Tissue | A group of similar cells that work together to perform a specific function. |
| List what is inside the nucleus | Chromatin, Pores, Nuclear envelope, Nucleolus. |
| Describe the difference between animal and plant cell structures | Cell wall is only in a plant cell and not an animal cell, |
| Where are ribosomes are made, and why they are so important | Float in the cytoplasm function as factories to produce proteins. |
| Describe what the endoplasmic reticulum does for ribosomes | Passageways carry proteins and other materials from one part the cell to another. |
