How does temperature affect natural vegetation?

Increased temperatures cause higher evaporation and a greater shortage of water. Temperature has an impact on vegetation since few plants can thrive if it is too cold (less than 6 degrees Celsius). Plant development, on the other hand, is enabled by high temperatures (over 20 degrees Celsius). High temperatures can also cause plant diseases and insects, which are further discussed in this article.

Temperature affects natural vegetation in three ways: hot temperatures are harmful to most plants while cold temperatures limit plant growth and distribution. As temperatures increase, so will the amount of heat-related stress that plants experience. This can lead to many problems for the plants, including death. Warming temperatures can also have positive effects on some species by encouraging them to spread their range if they are able to adapt quickly enough. But there are dangers when warming temperatures cause the spread of pests and diseases or when they alter the landscape due to forest fires or desertification.

Natural vegetation responds to changes in temperature by moving or adapting. Some species may move to find cooler places while others may change their behavior or life cycle in response to increased temperatures. For example, trees grow faster and larger than expected leading some scientists to believe that a major extinction event occurred with the rapid expansion of woodlands after the asteroid hit Earth 65 million years ago. The impact from this collision was likely responsible for causing the Late Paleozoic Ice Age which lasted for about 10 million years leading up to the recovery of modern vegetation patterns.

Why do plants have the right temperature?

Temperature has an important role in plant growth and development. Temperature, like light, carbon dioxide, air humidity, water, and nutrients, effects plant development and, ultimately, crop production. Plants need temperatures that are high enough for life but not so high that it causes damage through heat stress. Temperatures above 45 degrees Celsius (113 degrees Fahrenheit) can cause serious injury to plants. Low temperatures can cause problems as well; plants must be able to go into freezing temperatures without being damaged.

The range of temperatures that plants require depends on what stage of growth they are in. Young plants need warmer temperatures than older ones. Summer crops require higher temperatures than winter ones. High-temperature damages occur when the temperature is too high for a long period of time or rises too quickly after being low. Low-temperature damages happen when the temperature falls below freezing for a long period of time.

Plants use several ways to protect themselves from high and low temperatures. Their cells contain fluid inside them called "plasma". At normal temperatures, this plasma flows around the cells giving them support and protecting them from damage caused by its movement away from their center. But at high temperatures, this fluid begins to move faster, causing damage to the cell.

How does temperature affect plant distribution?

The effect of temperature on plants Most plant activities, including photosynthesis, transpiration, respiration, germination, and blooming, are influenced by temperature. Photosynthesis, transpiration, and respiration all increase as temperature rises (to a point). As temperature increases, so does the rate of these three processes. This increased rate can lead to over-flowering or under-flowering of plants if they are not given enough time to recover between periods of activity.

Temperature affects the distribution of plants in two ways: by determining when they will bloom and by influencing where they will grow. If temperatures remain below 10 degrees Celsius (50 degrees Fahrenheit), flowering will be limited primarily by day length. Plants need light signals from the sun to trigger their reproductive systems. As temperatures rise above 15 degrees Celsius (59 degrees Fahrenheit), more frequent frost damage can limit growth and reproduction. At very high temperatures, such as those found in heat waves, most plants will die.

Plants need moisture for healthy growth and development. The amount of water required varies depending on the species, but generally speaking, plants grown in dry conditions will require more water than those growing in moist soil. Temperature also influences how much water plants require. Warm temperatures cause the water content of plants' cells to increase, while cold temperatures cause it to decrease.
