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 |
| Answer» D. Conduction and respiration | |
|
Explanation: 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. |
