Understanding Hydroponics and Aeroponics

What is the primary difference between hydroponics and aeroponics?

• Hydroponics uses soil, while aeroponics uses air.

• Hydroponics uses a nutrient solution, while aeroponics uses a mist of nutrient solution.

• Hydroponics uses sunlight, while aeroponics uses artificial light.

• Hydroponics uses solid media, while aeroponics uses liquid media.

Which of the following is a key component of the nutrient film technique (NFT) in hydroponics?

• Soil

• A thin film of nutrient solution

• Rockwool

• Aggregate culture

In hydroponics, what does the term "parts per million (ppm)" refer to?

• The concentration of nutrients in the solution

• The number of plants per square meter

• The amount of water used per day

• The growth rate of plants

Which of the following is NOT a type of hydroponic system?

• Aeroponics

• Aggregate culture

• Circulating systems

• Soil-based systems

What is Rockwool commonly used for in hydroponics?

• As a nutrient solution

• As a growing medium

• As a pest control method

• As a light source

Which process in plants involves the conversion of glucose and oxygen into energy, carbon dioxide, and water?

• Photosynthesis

• Respiration

• Transpiration

• Germination

What does the term "ponics" refer to in the context of plant cultivation?

• The use of soil for growing plants

• The use of water-based systems for growing plants

• The use of air-based systems for growing plants

• The use of light-based systems for growing plants

Which of the following is a benefit of using hydroponics over traditional soil-based agriculture?

• Requires more water

• Allows for faster plant growth

• Increases the need for pesticides

• Reduces the need for artificial lighting
