What value to a plant is the ability to lose water through transpiration?
Transpiration is the property that allows a vascular plant to move water from the roots up the stems to the leaves, carrying nutrients with it. This is a very old concept; actually transpiration is an essential evil to the plants. The plants have stomata for gaseous exchange and during this exchange of gases the water vapors also get diffused.
What is the difference between photosynthesis and breathing in plants?
transpiration is the loss of water conducted by plant through the stomata. the evaporation of water from the leaves results in a suction force which pulls the water up the xylem vessels and out through the stomata. this suction force due to transpiration is the main factor in lifting water and dissolved mineral salts up the plant from the roots to the leaves. respiration on the other hand is a process wereby plants obtain energy by the oxidation of food substances, glucose in other words. this energy is thus utilized for cellular activities and in various chemical reactions going on inside the plant. breathing, a part of respiration, is completely different from transpiration as it involves gaseous exchange from the atmospheric air.
What is the process of gas exchange in plants?
The process of gas exchange in plants is known as photosynthesis. Animals let out carbon dioxide that the plants convert to oxygen.Gaseous Exchange in PlantsIn the plants the gaseous exchange occurs through surface of leaves. Special apparatus called as stomata are present on the surface on the leaves and green stem, through which plants exchange gases like carbon dioxide and oxygen. Stomatal opening is affected by various environmental factors like temperature, humidity, wind speed etc and thus affecting the gaseous exchange. In the roots of the plants the gaseous exchange occurs through pores called lenticles. The process of gaseous exchange occurs by the process of diffusion in these cases.Mechanism of gaseous exchange in plantsPlants require less energy per unit mass than animals as they possess lower metabolic rates. They do not therefore need to maintain the high rates of gaseous exchange of the more complex animals, and rely on diffusion through spaces between the cells (intracellular air spaces). No special ventilation mechanisms exist. Flowering plants exchange gases by diffusion through pores called stomata in their leaves and on their green stems, or if the stems are woody, through cracks in the bark or slits called lenticels.Gas exchange in leavesLeaves are thin and have a large surface area, and so they are the main sites of gaseous exchange. Inside the leaf of dicotyledons, there is a spongy mesophyll with large air spaces which allow efficient diffusion. There are also especially large spaces around the stomata. Since the system relies on diffusion, water can diffuse out of the plant just as easily. It is obvious that even a small amount of water stress may reduce plant growth (and therefore yield if it is a crop plant). Plants have protective mechanisms whereby they can close their stomata if water is in short supply. This depends on the action of plant hormones, particularly abscisic acid.The oxygen movements inside the plant are determined by the diffusion gradients that exist in the intercellular air spaces. In this way oxygen travels towards the cells and dissolves in the surface moisture of their walls. From here it passes by diffusion into the cells themselves. Carbondioxide leaves the plants by the same pathway but in the reverse direction. (Fig 1)The entire process would have become more complex in the photosynthesizing plants. Here the oxygen is produced by the chloroplasts as a waste product of photosynthesis. The oxygen may be used up immediately in respiration by mitochondria contained in the same cell, and waste carbondioxide from respiration may be used by the chloroplasts for photosynthesis.
How do plants get atmospheric nitrogen?
some plants have bacteria in their roots which contain nitrogen when plants want nitrogen they exchange their food made them with nitrogen. Example: pea plants contain bacteria called rhizobium which contains nitrogen
What is the value of transpiration to plant?
Transpiration is vital for plants as it helps in the absorption and transportation of water and nutrients from the roots to other parts of the plant. It also aids in cooling the plant and maintaining its temperature, as well as maintaining turgidity in cells, which is necessary for structural support. Additionally, transpiration plays a role in the movement of water through the soil and the regulation of mineral uptake by roots.
What is pneumatophores?
pneumatophores are lateral roots that grow upward (negative geotropism) for varying distances and function as the site of oxygen intake for the submerged primary...or they are a specialized root of certain swamp plants, such as the mangrove, that branches upwards, rising above ground, and undergoes gaseous exchange with the atmosphere.Pneumatophores are aerial roots that are specialized for gaseous exchange and are found in swamp plants and mangroves.
What can convert nitrogen in the air into a form plants can use?
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.
How do roots of plants get oxygen needed by them for breathing?
Plants respire through tiny openings or holes called stomata that are present on the underside of the leaves. Stomata trap air (like oxygen) and the exchange of gases takes place in side the plant cells.
What are some examples of pneumatophores roots?
Breathing is the movement of air in and out of an organism to supply oxygen and expel carbon dioxide and water. This process is necessary for respiration which extracts energy from carbohydrates such as sugar. In plants, movement of air in and out of the organism usually occurs mainly via holes called stomata in the leaves. A good example of breathing roots occurs in mangroves where the roots are often covered by stagnant muddy water.

How do plant roots breathe in the soil?
Plants breathe in the soil with the help of their roots . Some plants such as mangroves grow in muddy soil which does not contain much oxygen. To get some air, some mangroves give out special roots called breathing roots. Breathing roots are lined with special cells ( called lentils ) that absorb air. But , plants usually do not breathe through their roots ( mostly through leaves ) . Mostly soil particles can go through roots but I don't know how.

Is it possible to exchange the roots of one plant for those of another?
Yes, it is possible to exchange the roots of one plant for those of another.Specifically, the technique in question is called grafting. It requires separating each of two plants' set of roots and stems. The grafted root will be called stock and the grafted stem scion.
