Which of the following processes are associated with plants during dark period? (a) Photosynthesis and respiration (b) Respiration and transpiration (c)Transpiration and conduction (d)Conduction and respiration
Option D) Conduction is the process by which vital nutrients are transported to the different parts of a plant. This process is independent of the light factor. Respiration process in plants is the intake of carbon-dioxide and exhales oxygen during the day as the plants gets energy through the photosynthesis process in which the carbon-dioxide is converted into sugars using the sun light energy, as this process uses carbon-dioxide and water, the resulting gas oxygen is given out as a waste product. During the night, as the photosynthesis process cannot be happening without sun, so it exhales the carbon-dioxide itself.
