Question

How does food prepared by leaves is utilised by roots? Explain.

Answer 1

The photosynthetic process occurs only in the chloroplasts, tiny subcellular structures contained in the cells of leaves and green stems. In photosynthesis, the sun’s energy combines hydrogen from water (H20) with carbon dioxide (CO2) turning them into carbohydrates. Oxygen (O2) is given off as a by-product of photosynthesis. The chemical equation for the process of photosynthesis is: 6CO2 + 6H20 + light C6H12O6 + 6O2 This process is directly dependent on the supply of water, light and carbon dioxide. Any one of the factors on the left side of the equation (carbon dioxide, water, or light) can limit photosynthesis regardless of the availability of the other factors. If any one of these factors is limiting, then the whole process slows down or stops. An implication of drought or severe restrictions on landscape irrigation is a reduction in photosynthesis and thus a decrease in plant vigor. In a tightly closed greenhouse there can be very little fresh air infiltration and CO2 levels can become limiting. This in turn limits plant growth because the production of sugars needed to do the work involved with growing is limited. Many greenhouses provide supplemental CO2 to stimulate plant growth. The rate of photosynthesis is somewhat temperature dependent. For example, with tomatoes, when temperatures rise above 96 degrees Fahrenheit the rate of food used by respiration rises above the rate that food is manufactured by photosynthesis. Plant growth comes to a stop and produce loses its sweetness.

Answer 2

when plants give the light from sun .this process called photosynthesis.
we give them water, sun light in this way plants make their own food.
IN this way serve food their all parts .
exp: root ,leaf.
