Leaf Function Function ---> Absorb light and carbon dioxide to undergo photosynthesis Leaf Structures Chlorophyll… Absorbs sunlight Vein… Provide support for the leaf and transport water Stomata… Allows for carbon dioxide to enter the leaf Mesophyll Cells… Transparent structure to let maximum light in Epidermis… Thin and transparent top layer Cuticle… Protects leaf, but is thin enough to let light pass through
Chloroplast Function Function ---> Absorb sunlight, convert light to sugar, produce NADH and ATP through photosynthesis Contain chlorophyll, which make plants green Split H20 into H+ and O2 Located in mesophyll cells Chloroplast Structures Outer Membrane… Permeable to small molecules and ions Inner Membrane… Regulates passage of materials. Synthesizes fatty acids, lipids, and carotenoids Thylakoids… Area where light reactions occur Stroma… Dense interior aqueous fluid, area where the Calvin Cycle occurs Granum… A stack of thylakoids
