, 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?
1. osmosis
2. diffusion
3. passive transport
4. active transport - ANS Active transportation
