Detailed explanation-1: -Photosynthesis and respiration Plants grow best when daytime temperature is about 10 to 15 degrees higher than nighttime temperature. Under these conditions, plants photosynthesize (build up) and respire (break down) during optimum daytime temperatures and then curtail respiration at night.
Detailed explanation-2: -Plant has unlimited growth. It can grow continuously throughout its life. The growth of plant is mostly influenced by its surrounding environment. It has an open type of growth.
Detailed explanation-3: -All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.
Detailed explanation-4: -Sunlight provides energy to the plant while water and carbon dioxide provide all the important nutrients required by the plant for food preparation. Oil is not required by the plant in food prepration.
