How Does Wind Affect Plants

Wind Affect on Plants Air in motion is called wind. Wind affect plants directly by increasing transpiration, by delivering heat to relatively cool leaves or dissipating the heat load of isolated leaves, by causing various kinds of mechanical damage and by scattering pollen’s and dispersal of seeds and fruits. Wind plays important role as an ecological factor especially on flat plains, along seacoasts ...

Temperature as an Ecological Factor in Plants

Temperature as an Ecological Factor Temperature is one of the important ecological factors affecting the growth and reproduction of plants. All organisms depend upon a certain temperature or range of temperature. There is relatively little biologic activity below O°C due to immobilization of water or above 500°C because very high temperature denatures the enzymes. The plants have both minimal and ...

Adaptation of Plants to Temperature

Adaptation of Plants to Temperature

Physiological Responses and Adaptations of Plant to Temperature The adaptation of plants to temperature have greatly succeeded in development with the passage of time. They have developed a number of morphological and physiological characteristics during the course of evolution in order to meet extremes of temperature conditions. Formation of dormant bulbs, tubers; leaf fall and associated dormancy during winter or dry season ...

Drought Resistance Mechanism in Plants

Drought Resistance Mechanism Drought can be defined as an extreme fluctuation from the rainfall (usually than 75% of the normal) at a certain place in a particular area. In water stress areas the plants (xerophytes and succulents) are adapted to shortage of water and dry season normally does not affect their growth. However, if the rainfall drops far enough below ...

Precipitation

Precipitation is condensation of water vapours in the form of rain, hail, snow etc.Precipitation (rainfall, snowfall) is the major source of soil moisture. All soil moisture is derived from precipitation. It is the driving force of the water cycle as well. Precipitation begins as water vapour derived from the surfaces of oceans in the atmosphere which condense to form clouds ...

Hydrologic Cycle Steps

Water exhibits cyclic flow between atmosphere, land and sea, and between living organisms and their environment. This is referred to as Hydrologic cycle or water cycle. Without cycling of water nutrients could not flow through the ecosystem, ecosystem could not function and life could not be maintained. Hydrologic Cycle Steps Water cycle is characterized by precipitation, interception, infiltration, and evaporation. ...

Ecophysiological Responses of Plants to Light

Ecophysiological responses of plants to light are photosynthesis, transpiration, seed germination, photoperiodism, reproduction and growth, and ecological classification. Ecophysiological Responses of Plants to Light The ecophysiological responses of light which affects plants in various ways are as follow: Photosynthesis The plant shoots are adapted to receive and absorb sunlight. Most leaves get saturated with only about 20% of full sunlight. ...

Temporal and Spatial Variations in Intensity of Light

Light varies in intensity, (i.e., temporal and spatial variations) duration and quality (proportions of red, yellow, blue, etc.) These variations are important in plant ecology; however, the intensity and duration of light is more important since it difficult to interpret the effect of quality of light for practical reasons. Temporal and Spatial Variations in Light Intensity The intensity of light exhibits spatial ...

Role of Light in Ecology

Role of light is an important role in this world. As Light factor is the most essential abiotic factor without the life cannot exist. The chief natural source of light is sunlight and has great ecological significance. It plays important roles in the life of plants, such as It provides energy to maintain life on earth. It is absorbed to ...
