Study Notes
- Cells have specific parts that perform different functions, allowing the cell to operate properly.
Cell Membrane
- Controls what enters and exits the cell.
Cytoplasm
- Holds the cell’s parts in place and facilitates chemical reactions.
Nucleus
- Stores DNA and controls the cell's activities.
Mitochondrion
- Produces energy for the cell.
Ribosome
- Constructs proteins for the cell.
Cell Specialization
- Cells develop unique shapes or features to enhance their performance of specific tasks.
Cell Communication
- Cells communicate through chemical messages, such as hormones, or electrical signals.
Living vs. Non-living
- Living organisms exhibit growth, change, reproduction, and responsiveness, whereas non-living entities do not.
Advantages of Specialized Cells
- Specialized cells enhance efficiency and contribute to proper body function.
Digestive System
- The digestive system consists of multiple organs that work together to break down food, absorb nutrients, and eliminate waste.
Mouth
- Initiates food breakdown through chewing and mixing with saliva.
Esophagus
- Transports food to the stomach.
Stomach
- Breaks down food using acid and enzymes.
Small Intestine
- Absorbs nutrients into the bloodstream.
Large Intestine
- Absorbs water and forms waste material.
Liver
- Produces bile to aid in fat digestion.
Pancreas
- Secretes digestive juices and insulin.
Gallbladder
- Stores and releases bile as needed.
