Stomata. Closed in hot sunny conditions. Water loss. Photosynthesis (slow down). Guard cells. Diffusion . Open = turgid = bulges. Closed = flaccid = collapse. 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.. Chapter 7. Outline. Introduction. Leaf Arrangements and Types. Internal Structure of Leaves. Stomata. Mesophyll. and Veins. Specialized Leaves. Autumnal Changes in Leaf Color. Abscission. Human and Ecological Relevance of Leaves. Leaf structure. The leaf has three main sections to it.. Cuticle.. Epidermis.. Mesophyll.. Cuticle. Epidermis. Palisade mesophyll. Spongy mesophyll. Epidermis. Cuticle. The cuticle:. Consists of a waxy material which improves impermeability. It is produced by the epidermis cells.. Lab 14. The Leaves. The .
