Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to perform photosynthesis. Magnesium is an important component of chlorophyll. The concentration of magnesium ions is higher in the root-hair cells of plants than in the soil. Which mechanism of ion uptake would best enable a plant to produce a steady supply of chlorophyll?
a- osmosis
b- diffusion
c- passive transport
d- active transport

Active Transport

Explanation:

Active transport components require the utilization of the cell's vitality, generally as adenosine triphosphate (ATP).   In the event that a substance must move into the cell against its fixation slope, that is, if the convergence of the substance inside the cell must be more prominent than its focus in the extracellular liquid, the cell must utilize vitality to move the substance. Some active transport systems move little sub-atomic weight material, for example, particles, through the membrane.

Plants take energy from the sunlight with the of chlorophyll so the plant starts the food chain. then an herbivore eats the plant and gets its energy.then a carnivore or a human eats the herbivore and gets its energy. : )
