Tutorial group: F Name: Aimukambetov Sanatzhan Lab partner: Aibekova Lazzat Measuring rate of water uptake by plant Introduction Transpiration is the one of the important processes in the plant where the water movement through a plant takes place and after evaporates mostly from leaves (also from stems and from flowers). In other words‚ transpiration is one of the most important mechanisms in plants which affect and support the flow of water. It is a process where evaporation of water through the leaves’

cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on top of the leaves surfaces‚ which in many plants have numerous on the undersides of the foliage. The stomas are

ABA is a naturally occurring compound in plants and is produced in the terminal bud‚ or top of the plant. It is synthesized in the Plastidal 2- C- Methyl- D- erythritol- 4- phsophate (MEP) Pathway. The production of ABA is accentuated by stresses such as water loss and freezing temperatures. It has a carbon backbone of C15

There are many factors that stress out plants and trees around our area. Because we are located in an urban setting‚ these plants and trees are more vulnerable to such stress. During our walk around campus‚ I noticed an enormous amount of stress done to the plants and trees. In this essay‚ I will explain my observations of urban stress around Temple University ’s campus and how each factor plays an important role and how it influences the survival of each plant and tree. Heat stress was a major

http://newmetode.Sharestiforp.com Plant tissue culture is a collection of techniques used to maintain or grow plant cells‚ tissues or organs under sterile conditions on a nutrient culture medium of known composition. Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation‚ including: • The production of exact copies of plants that produce particularly
