Study Notes
- All living things, or organisms, are made of cells
- Cells are the basic unit of structure and function in living things
- Cells form the parts of an organism and perform their respective functions
- The smallest organisms are made of one cell
- The largest organisms have trillions of cells
Cell Structure
- The structure of an object refers to what it is made of and how its parts are arranged
- A car's structure depends on materials like plastic, metal, and rubber and how they are arranged
- The structure of a living thing depends on how its cells are assembled
Cell Function
- A single cell has the same needs as an entire organism
- For a cell to stay alive, it must perform biological functions
- These functions include:
- Obtaining energy
- Bringing in nutrients and water
- Eliminating wastes
- Most organisms consist of many different cells that work together to help the organism stay alive, grow, and reproduce
- Cells in the circulatory system move blood around the body
- Blood provides fresh oxygen and removes the waste product carbon dioxide
- Heart cells pump blood to every part of the body
- The body's cells work together to keep it alive
Cells Are Everywhere
- If you take a swab from someone's tongue, you might see bacteria cells of different shapes, sizes, and functions under the microscope
