Plants : 4 Plants Autotrophs – produce their own food (glucose) Process called photosynthesis Mainly occurs in the leaves: a. stoma - pores b. mesophyll cells Stomata (stoma) : 5 Stomata (stoma) Pores in a plant’s cuticle through which water vapor and gases (CO2 & O2) are exchanged between the plant and the atmosphere. Found on the underside of leaves Stoma Mesophyll Cell of Leaf : 6 Mesophyll Cell of Leaf Photosynthesis occurs in these cells! Chloroplast : 7 Chloroplast Organelle where photosynthesis takes place. Thylakoid stacks are connected together Thylakoid : 8 Thylakoid Grana make up the inner membrane Question: : 9 Question: Why are plants green? Absorption of Light by Chlorophyll : 10 Absorption of Light by Chlorophyll wavelength Absorption Chlorophyll absorbs blue-violet & red light best Question: : 11 Question: During the fall, what causes the leaves to change colors? Fall Colors : 12 Fall Colors In addition to the chlorophyll pigments, there are other pigments present During the fall, the green chlorophyll pigments are greatly reduced revealing the other pigments Carotenoids are pigments that are either red, orange, or yellow Redox Reaction : 13 Redox Reaction The transfer of one or more electrons from one reactant to another Two types: 1. Oxidation is the loss of e- 2. Reduction is the gain of e- You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
