Photosynthesis Review

Write the equation for photosynthesis: 6C02 + 6H2O + Light ------------------> C6H12O2 + 6O2 Sort the molecules into inputs and outputs for the Light Dependent Reaction Input Light H20 ADP NADP+ Output O2 ATP NADPH Sort the molecules into the inputs and outputs for the Calvin Cycle (Light Independent Reactions) Inputs NADPH ATP CO2 Outputs Sugar ADP NADP+ Chloroplast Structure Label the image of the chloroplast. Grana Inner Membrane Outer Membrane Thylakoid Stroma Sort whether each step occurs in the Light Dependent Reactions or the Calvin Cycle. Light Dependent Reaction Takes place in the thylakoid membranes Water is split in Photosystem II NADP+ is converted to NADPH by accepting electrons from the light ADP is converted to ATP by ATP Synthase and the diffusion of H+ ions across the membrane Oxygen is released Electrons are transferred from Photosystem II to Photosystem I down an electron transport chain Takes place in only the daytime Calvin Cycle Takes place in the stroma CO2 (entering into the stomata from the atmosphere) is used Sugars are made from G3P Rubisco turns CO2 into a usable 3 carbon molecule Can take place in the daytime or nightime Uses NADPH and ATP to make G3P and regenerate RuBP molecules Leaf Cross Section Label the parts of the leaf. Xylem Phloem Vein Stomata Guard Cells Cuticle Palisade Mesophyll Spongy mesophyll Which leaf part is responsible for gas exhange? Guard Cell Mesophyll Stomata Cuticle Which leaf part will carry water from roots to the leaves for photosynthesis? Xylem Guard Cells Phloem Cuticle What controls the opening and closing of the stomata (in other words helps regulates gas exchange in plants) Guard Cells Cuticle Vein Mesophyll Which part of the leaf is responsible for bringing water and food from the leaf to the rest of the plant? Stomata Mesophyll Xylem Phloem Which products of photosynthesis are necessary for human survival? Select all that apply. O2 CO2 Light Glucose H20 Fill in the blanks. During photosynthesis light energy is converted into chemical energy.
