PPT-Transpiration in Plants

STEP 1 STEP 2 STEP 3 STEP 4 STEP 5 Pressure Flow Hypothesis Pressure Flow Hypothesis STEP 1 Food and water enters phloem of the stem through diffusion and osmosis STEP 2 Water from xylem is transferred to the phloem to help break downdissolve food in the phloem The water pressure is kept at low . Objectives:. *Define the term translocation. **Describe the translocation of applied chemicals such as systemic pesticides throughout the plant. *** Compare transpiration with translocation. Starter:. Warm up (11-23-15). Explain what you know about plants.. Try to be specific and use scientific terms if possible.. Outline. Objectives. Plant Background Info. Objectives. To gain background information about plants and how they colonized land. Introduction to Plants. Plants make . up . over 50% . of the living organisms on this planet. They belong to the kingdom . Plantae. There are five phylum:. Bryophyta. Filicinophyta. Coniferophyta. Angiospermophyta. Biology 3B Lab Plant Transpiration Page 2 of 3 4. Keep the cut end of the stem submerged.

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. AICE Biology 2017 . Introduction. Plants use photosynthesis to convert light energy to chemical energy . Simple organic substances, such as CO2, H2O and ions are used in their raw form to produce glucose and other carbohydrates..

Translocation through plant vascular system. Stomata open to take in CO. 2. for photosynthesis and water is lost by transpiration. Plants control stomata openings to regulate photosynthesis and transpiration . 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.. Chapter 4 pp. 47 -54. Lecture Outline. :. Evolution of vascular tissue. The xylem transports water and nutrients. The phloem transports sugars and other organic compounds. Xylem and phloem structure and function. . Budran.
