PPT-Transpiration and Its Significance

Dr Habibur Rahman Associate Professor J N College Boko Introduction The loss of water in the form of vapor from the living tissues of aerial parts of plant such as leaf stem leaves etc is termed as transpiration.

Turn in:. -Nothing . AP Lab 11: Transpiration. Transpiration. Evaporation of water from aerial parts of plants (not roots). Mr. West . AP Biology . 1. Definition. Transpiration. is the evaporation of water from the aerial parts of plants.. Of all the water plant absorbs, over 95-99% is transpired to the air as water vapor.. Cortex, cambium, epidermis, root cap, xylem, phloem. Stem . t.s. .. Cortex. -stores food as starch and supports the plant. . Cambium: . makes new xylem and phloem. . Epidermis: . protects stem and reduces water loss. . What is transpiration?. Starter: . Look at these wet clothes, how are they going to dry?. Even in winter?. . Glossary . Transpiration – the loss of water vapour from the leaves of plants through the stomata when they are open to allow gas exchange for photosynthesis.. Stomatal. Mechanism. Stomata. Stomatal. Mechanism. pores . or . gaps . in the lower epidermis through which gaseous exchange . and water loss take place. Found in leaves and stems. Surrounded by. . and the development of photosynthesis, transpiration and respiration.. How habitats are engrossed by plants and animals. Habitats are natural environments which organisms live.. Organisms such as plants and animals thrive in certain habitats.. A . S. tory of Clean . A. ir . by. Sandra J. . Connelly. Thomas . H. Gosnell School of Life . Sciences. Rochester .

Frequent immersion in fog . contributes to maintain high water yield from watersheds within . montane. cloud belts because of additional water inputs (fog, drizzle) and the s. uppression . of . plant transpiration.. GCSE (or any course for students aged. 11-16). Outcomes. Be able to label the structure of a typical leaf. Describe and understand the role of stomata and the waxy cuticle in transpiration. Information for teachers. Do now activity:. Which cells open and close the stomata?. Describe the process of transpiration?. Explain why the root hair cell in the plant needs a large surface area.. GOOD PROGRESS:. - . Identify. How does water move into, through and out of a plant?. Transpiration. Transpiration. – evaporation of water from the leaves.. Transpiration stream. – movement of water through the plant.. Root Structure. . Budran. Plant cells as osmotic systems. OP . TP. WP. TP=WP. DPD (SF). In pure solvent. SF is related with OP and TP . SF = OP –TP. For fully turgid cells. SF = 0 . OP = TP . For fully plasmolyzed cells .
