Hint:
1. There are many micronutrients and macronutrients which are responsible for the growth and
development of plants.
2. Leaves are the growing region of plants. So, the nutrient which is responsible for growth whose
deficiency is responsible for the yellowing of leaves.
Complete answer:
1. calcium is an essential micronutrient in plants. Calcium is mainly used in cell wall formation and cell membrane stability.
2. It helps plants to protect themselves from the stress condition. It is also helpful in maintaining the
The condition of homeostasis in plants and signal generation is also done by calcium.
3. sodium is not an essential nutrient, it is used in small amounts and hence it is counted in micronutrients.
4. sodium helps in the member transport system.
5 Increase in the amount of sodium may cause salinity stress conditions in plants.
6. Potassium is an essential nutrient in plants. It is mainly responsible for the growth of plants. So, it is located on the tip of the root and leaves hence these both are the growing parts of the plant.
7. sulfur is a macronutrient in plants. It helps in the forming of different enzymes, protein, and
The vitamin also plays an important role in the process of photosynthesis and nitrogen fixation.
8. Molybdenum is also an essential macronutrient in plants. It is helpful in the process of nitrogen
fixation and synthesis of amino acids in plants.
Hence, the nutrient responsible for the yellow edges of the leaves of the plants is potassium.
So, the correct answer is “Option C Potassium”.
Note: Sometimes when there is a deficiency of potassium then the sulfur complete function of potassium.
I'm a plant nutrition enthusiast with a deep understanding of micronutrients and macronutrients crucial for the growth and development of plants. My expertise extends to the specific roles these nutrients play in plant physiology, addressing issues such as yellowing of leaves due to nutrient deficiencies.
Let's break down the concepts mentioned in the article:
-
Calcium (Ca):
- Essential micronutrient in plants.
- Mainly used in cell wall formation and cell membrane stability.
- Aids in plant protection under stress conditions.
- Contributes to maintaining homeostasis and signal generation in plants.
-
Sodium (Na):
- Not an essential nutrient in plants.
- Used in small amounts and classified as a micronutrient.
- Plays a role in the membrane transport system.
- Excessive sodium may lead to salinity stress conditions in plants.
-
Potassium (K):
- Essential nutrient in plants.
- Mainly responsible for plant growth.
- Located in the tip of the root and leaves, which are the growing parts of the plant.
- Deficiency can lead to yellowing of leaves.
-
Sulfur (S):
- Macronutrient in plants.
- Aids in the formation of enzymes, proteins, and vitamins.
- Important for photosynthesis and nitrogen fixation.
-
Molybdenum (Mo):
- Essential macronutrient in plants.
- Supports the process of nitrogen fixation and synthesis of amino acids.
In the context of the article, it states that the nutrient responsible for the yellow edges of the leaves is potassium. This is because potassium is a key player in plant growth and is located in the growing parts of the plant, such as the tip of the root and leaves. It's worth noting that sometimes when there is a deficiency of potassium, sulfur may compensate for its functions.
So, the correct answer according to the article is "Option C: Potassium."
