Why do different plants transpire at different rates?
Why do you think different species of plants transpire at different rates? The metabolic rate of the plant = plants with a higher metabolism have a higher transpiration rate. The amount of water in the soil – plants that have access to more soil water will transpire at a higher rate than those which don’t.
How does light affect plant transpiration?
Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster. This is because the stomata remains open to allow the inward diffusion of carbon dioxide for photosynthesis.
Why is light important in transpiration?
Light increases the rate of water absorption and the resulting increased turgidity of the two guard cells, which form the boundary of each stoma, brings about the opening of the stomates, increasing transpiration rate.
How do different factors affect the rate of transpiration?
Factors that affect the rate of transpiration also affect water uptake by the plant. If water is scarce, or the roots are damaged, a plant may wilt….Factors affecting rate.
Factor | Effect | Explanation |
---|---|---|
Wind speed | Increased | Moving air removes water vapour, increasing the rate of diffusion of water vapour from the leaf |
What factors affect translocation in plants?
Factors Affecting Translocation Rate The rate of photosynthesis (which is affected by light intensity, CO2 concentration, temperature, etc.) The rate of cellular respiration (this may be affected by any factor which physically stresses the plant)
How is translocation important to plants?
It is an important process in plants because the source of production i.e., the location of photosynthesis is not the same as the site at which nutrients are stored; as a result it is essential that the nutrients be moved throughout the plant via translocation otherwise the food produced in the leaves will not be able …
What are the factors affecting transpiration and translocation in plants?
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.
What is the process of translocation in plants?
Photosynthesis produces glucose in the green parts of plants, which are often leaves. This is then converted into sucrose. The movement of sucrose and other substances like amino acids around a plant is called translocation . …
Which sugar is translocated in plants?
sucrose
What is translocation in plants Class 10th?
Translocation is the process by which plants deliver minerals, plant growth hormones, water, and organic substance over long distances throughout the plants (from leaves to other parts). These food nutrients are translocated in the form of solutes in a solution known as phloem sap.
What is the major requirement for translocation of food in plant?
The process of transport of food and mineral in plants is called translocation. When food like glucose or sucrose it transferred to phloem tissue, using ATP, the concentration of water molecules decreases in that area this results in movement of water into the cells due to osmosis.
Who helps in translocation of food in plants?
Phloem
Which type of water is absorbed by plants?
Capillary water
What are the signs of phosphorus deficiency?
Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change.
