A sheltered structure or building is designed to protect plants from too much sun and heat.

True
False

Correct Answer

A. True

Explanation

A sheltered structure or building is specifically created to provide protection to plants from excessive sunlight and heat. This can be achieved by using materials that provide shade or insulation, such as a greenhouse or shade cloth. This helps in creating a controlled environment for the plants, preventing them from being damaged or stressed due to extreme weather conditions. Therefore, the statement is true.

What is/are the advantage(s) of hydroponics?

Reduced spaces needed for cultivation.
Weed control is not required
Elimination of soil-borne pests and diseases.
None of the above

Correct Answer(s)

A. Reduced spaces needed for cultivation.
A. Weed control is not required
A. Elimination of soil-borne pests and diseases.

Explanation

Hydroponics offers several advantages over traditional soil-based cultivation. Firstly, it requires reduced spaces for cultivation as plants can be grown vertically or in smaller areas without the need for large fields. Secondly, hydroponics eliminates the need for weed control as there is no soil for weeds to grow in. Lastly, by eliminating soil, hydroponics also eliminates soil-borne pests and diseases, leading to healthier plants. Therefore, all of the given options are advantages of hydroponics.

5.

For hydroponics, the substrate is the material in which the plant root will develop, and it can either be solid or liquid.

True
False

Correct Answer

A. True

Explanation

In hydroponics, the substrate refers to the material in which the plant root will grow. It can be either solid or liquid. This means that the plant is not grown in soil but rather in a medium that provides support and nutrients. Therefore, the statement is true.

For hydroponics, consideration(s) for selecting substrate is/are:

Availability, access and cost.
It should not be contaminated with industrial waste.
It must be capable of maintaining moisture and draining excess water.
None of the above

Correct Answer(s)

A. Availability, access and cost.
A. It should not be contaminated with industrial waste.
A. It must be capable of maintaining moisture and draining excess water.

Explanation

The correct answer is a combination of all the options provided. When selecting a substrate for hydroponics, availability, access, and cost are important factors to consider. Additionally, the substrate should not be contaminated with industrial waste, as this could harm the plants. Lastly, the substrate should be capable of maintaining moisture and draining excess water to ensure proper root health. Therefore, all of the options provided are considerations for selecting a substrate in hydroponics.

7.

What is/are the consideration(s) for a suitable location for a hydroponics system?

Avoid heavily shaded and extremely windy areas.
Protection from animals.
Away from contaminated water and other contaminants.
Away from trees/crops affected by pests or diseases.

Correct Answer(s)

A. Avoid heavily shaded and extremely windy areas.
A. Protection from animals.
A. Away from contaminated water and other contaminants.
A. Away from trees/crops affected by pests or diseases.

Explanation

The suitable location for a hydroponics system should be free from heavy shade and strong winds to ensure optimal growth conditions for the plants. It should also be protected from animals to prevent damage to the crops. Additionally, the location should be away from contaminated water and other contaminants to maintain the purity of the system. Lastly, it should be kept away from trees or crops affected by pests or diseases to prevent the spread of such issues to the hydroponics system.

Examples of closed hydroponic systems are Nutrient Film Technique and Floating Root System.

True
False

Correct Answer

A. True

Explanation

Closed hydroponic systems are designed to recirculate and reuse the nutrient solution, rather than allowing it to drain away. The Nutrient Film Technique (NFT) and Floating Root System are both examples of closed hydroponic systems. In NFT, a thin film of nutrient solution continuously flows over the roots of the plants, providing them with the necessary nutrients. In a Floating Root System, the plants are suspended in a foam raft, with their roots submerged in the nutrient solution. Both of these systems are considered closed because the nutrient solution is not wasted or drained away, but rather recycled, making the statement true.

What type of hydroponic system is shown in the image below?

Deep Water Culture System
Floating Root System
Nutrient Film Technique
Wick System

Correct Answer

A. Nutrient Film Technique

Explanation

The correct answer is Nutrient Film Technique because in the image, there is a thin film of nutrient-rich water flowing continuously over the roots of the plants. This is a characteristic feature of the Nutrient Film Technique hydroponic system.

10.

What type of hydroponic system is shown in the image below?

Floating Root system
Nutrient Film Technique
Deep Water Culture System
Wick System

Correct Answer

A. Floating Root system

Explanation

The image shows a hydroponic system where the roots of the plants are suspended in water, with no solid medium for support. This is known as a floating root system. In this system, the plants receive their nutrients directly from the water, and the roots float on the surface. This method allows for easy oxygenation of the roots and efficient nutrient uptake.
