Temperature affects photosynthesis by allowing plants to photosynthesize (i.e., build up) and respire (i.e., break down) when there is optimum daytime temperature. It also enables plants to curtail the rate of respiration at a cooler night. With high temperatures, respiration increases and the products of photosynthesis are used faster than they are produced.Know More
The rate of the chemical reactions during photosynthesis increases with temperature. However, temperatures above 40 C causes the process to slow down. This occurs because the enzymes involved in photosynthesis are sensitive to temperature. Additionally, low temperatures cause plants to grow poorly. It slows down photosynthesis, thus resulting in slower growth and lower yields.
Enzymes are easily affected by temperature. When it is too cold, they move around much slower, thus unable to allow for a reaction to occur. When it is too hot, the rate of reaction increases. Heat energy leads to more collisions between the substrate and the enzyme.
Different plants require different optimal temperatures to grow well. Plants that grow in colder climates grow best at low temperatures. For a certain number of days, buds of plants need to get exposed to chilling hours, which is below a critical temperature, to resume growth during spring. When dormant, they can withstand even lower temperatures. After the rest period, they become more vulnerable to weather conditions, especially cold temperatures.Learn more about Botany
Temperature affects the percentage of seeds that germinate and the rate of germination. Seeds kept at higher temperatures are more likely to deteriorate and not germinate. Once seeds start to germinate, higher temperatures stimulate faster germination up to an optimal temperature, after which the speed of germination declines.Full Answer >
Saltwater has a negative impact on plant growth and development. The specific effects of saltwater on plants varies by species.Full Answer >
Chlorine is a micronutrient that is essential to plant growth. If a plant accumulates too much chlorine in its leaf tissue the leaves become scorched or burnt in appearance.Full Answer >
Fertilizers are much to plants what vitamins are to humans; they provide supplemental nutrients and minerals that plants might not otherwise obtain due to inadequate soils or scarcity of resources. Fertilizers may be organic or synthetic and used in commercial and residential settings. They contain nutrients and minerals used by most plants and flowers, and consumers may purchase fertilizers formulated to promote the growth of specific species.Full Answer >
