Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which primary plant nutrient promotes strong root growth in young seedlings?
A
Phosphorus
B
Potassium
C
Nitrogen
D
Iron
Explanation: 

Detailed explanation-1: -Phosphorus is particularly important in early growth stages. It is mobile within the plant and promotes root development (Particularly the development of fibrous roots), tillering and early flowering.

Detailed explanation-2: -Phosphorus is a vital component of ATP, the “energy unit” of plants. ATP forms during photosynthesis, has phosphorus in its structure, and processes from the beginning of seedling growth through to the formation of grain and maturity. Thus, phosphorus is essential for the general health and vigor of all plants.

Detailed explanation-3: -Phosphorus helps transfer energy from sunlight to plants, stimulates early root and plant growth, and hastens maturity.

Detailed explanation-4: -Phosphorus in plants is key in capturing, storing, and converting the sun’s energy into biomolecules, such as adenosine triphosphate (ATP), that drive biochemical reactions (e.g., photosynthesis) from germination through the formation of grain to maturity.
