Water Through a Plant? Introduction Plants, just like other organisms, must be able to transport materials from one part to another. Plant transport systems consist of two large tubes made of vascula Daily Warm-up Monday, April 21. st. . What processes help move water up a tree?. HW: . -Read 42.4. Turn in:. -Nothing . AP Lab 11: Transpiration. Transpiration. Evaporation of water from aerial parts of plants (not roots). 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. 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.. Biology 3B Lab Plant Transpiration Page 2 of 3 4. Keep the cut end of the stem submerged. Carefully attach the cut end of the corn seedling to t 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. . Code: 308 Bot.

Absorption of salts by roots is both passive and active. . 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. 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.. 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..
