Study Notes
Transformer Function in Electric Circuits
- A transformer alters voltage levels in an electric circuit, enabling efficient power transmission over long distances.
- It consists of primary and secondary coils that work through electromagnetic induction to increase (step-up) or decrease (step-down) voltage.
SI Unit of Electric Power
- The SI unit of electric power is the watt (W), defined as one joule per second.
- Power can also be expressed in kilowatts (kW), where 1 kW = 1,000 W.
Purpose of a Fuse in Electric Circuits
- A fuse protects electrical circuits by preventing overloads and short circuits.
- It contains a wire that melts and breaks the circuit if current exceeds a safe level, thus preventing potential damage and hazards.
Function of Stomata in Plants
- Stomata are small openings on the plant's surface that facilitate gas exchange, allowing carbon dioxide in and oxygen out.
- They also play a crucial role in transpiration, helping regulate water loss from the plant.
Movement of Water and Nutrients in Plants
- The process primarily responsible for transporting water and nutrients from roots to other parts of the plant is called transpiration.
- This process creates a negative pressure in the leaf, pulling water upward through xylem vessels.
Primary Function of Guard Cells
- Guard cells surround each stoma and regulate its opening and closing to control gas exchange and water loss.
- They respond to environmental conditions, adjusting the size of the stomatal pores to maintain homeostasis in the plant.
