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 …
Q. How do plants regulate water?
Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis .

Q. Which transpiration can be regulated?
Lenticular transpiration can be regulated by coating the bark of the trees, thereby reducing the rate of loss of water from the surface of the bark.
Q. How does transpiration occur in plants?
Transpiration occurs during photosynthesis when the stomata open for the passage of carbon dioxide gas. Water transported to the leaves is converted to a gas. As carbon dioxide is allowed into the leaf, water vapors escape through evaporation to the atmosphere.
Q. 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)
Q. What are the factors affecting transpiration and translocation in plants?
Factors affecting transpiration
| Factor | Change in factor that increases transpiration rate |
|---|---|
| Temperature | Increase |
| Humidity | Decrease |
| Air movement | Increase |
| Light intensity | Increase |
Q. How do environmental factors affect transpiration?
Transpiration is affected greatly by the environment factors such as temperature, light relative humidity, wind, and so on. Transpiration increases with increasing air temperature and wind velocity. At constant temperature and wind velocity, transpiration rate is governed by moisture content of air.
Q. What do plants need to grow and survive?
Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN).
Q. Why is loss of water important for a plant?
The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis.
Q. How do plants survive?
Plants have specific needs – light, air, water, nutrients, and space – to survive and reproduce. Almost all plants need these five things to survive: Light. Air.
