Which component of chlorophyll makes plant material grow faster and greener?

course textured particles
Nomenclature
Water Holding Capacity
Nitrogen

The correct answer is: Nitrogen

Nitrogen is the correct answer because it is an essential component of chlorophyll, the green pigment in plants responsible for photosynthesis. Nitrogen is a primary nutrient required for plant growth and is crucial for the production of chlorophyll. Adequate nitrogen levels in the soil promote healthier, lusher, and greener plant growth by ensuring that plants have enough chlorophyll to carry out photosynthesis efficiently. The other options (course textured particles, Nomenclature, and Water Holding Capacity) are not directly related to the component of chlorophyll that makes plant material grow faster and greener, making them incorrect choices for this question.
