Study Notes
Cell Structure and Function
- Plant cells have a cell wall and chloroplasts, which distinguish them from animal cells.
- The mitochondria are the powerhouse of the cell and produce energy in the form of ATP.
Cellular Transport
- Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.
Skeletal System
- The skeletal system provides protection, facilitates movement, and produces blood cells.
Scientific Instruments
- A force meter is used to measure the amount of force exerted by muscles.
Nutrition
- A healthy diet consists of calcium, lipids, carbohydrates, and protein.
Respiration
- The main gas exchanged in the alveoli during respiration is oxygen.
Cell Components
- The nucleus is the control center of the cell, often referred to as the "brain of the cell".
Cellular Transport Mechanisms
- Diffusion is the movement of a substance from high to low concentration.
- Osmosis, endocytosis, and active transport are distinct cellular transport mechanisms.
