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?
Answers
The process by which plants take up mineral ions from the soil through the root hairs against the concentration gradient is known as active transport.
Active transport in the roots is facilitated by :
1) Numerous mitochondria in the root hair cells.
Since active transport requires energy, the mitochondria provides energy in form of ATP.
2) Oxygen in the soil that is absorbed by the roots and that is used in respiration to produce more energy.
3) Protein channels in cell membrane for active transport.
The means of transportation of magnesium ions to the leaves is thus by Active transport.
The plants have the xylem and the phloem.
The xylem provides the water and the mineral those are absorbed by the root and is passed to the whole plant by active transport process.
The minerals especially Magnesium is an important constituent of chlorophyll and is present in root hair.
Chlorophylls are essential to perform photosynthesis.
