Irrigation means to water the crops, on doing this the crops are protected from the hot air currents and frost.
I am here asking a question basically it's a sentence of science book ...
The Meaning of the Sentence:
The sentence states that when water is supplied to crops during irrigation, it serves two purposes: it protects the plants from hot air currents and also helps prevent frost damage.
Explanation:
- Water Supply during Irrigation: When crops are irrigated, water is supplied to the plants. This is important as water is essential for the growth and development of plants. It helps in various physiological processes like photosynthesis, nutrient absorption, and maintaining turgidity.
- Protection from Hot Air Currents: Hot air currents are strong air movements that carry heat. These currents can cause damage to crop plants by increasing the rate of transpiration and drying out the plants. However, when water is supplied to the crops during irrigation, it helps to cool down the plants and provide a protective layer. The water on the surface of the plants evaporates, taking away heat and cooling the plant tissues. This helps in protecting the plants from the negative effects of hot air currents.
- Protection from Frost: Frost occurs when the temperature drops below freezing point, leading to the formation of ice crystals on the plant surfaces. This can cause damage to the plants by freezing the water inside the plant cells and disrupting their structure. When water is supplied to the crops during irrigation, it helps in preventing frost damage. The water on the plant surfaces freezes first, forming a protective layer of ice that insulates the plant tissues and prevents further freezing. This protects the plants from the harmful effects of frost.
Therefore, the sentence from the science book emphasizes the importance of water supply during irrigation. It explains how water plays a crucial role in protecting crop plants from both hot air currents and frost, ensuring their healthy growth and preventing damage.
