Photosynthesis .
photosynthesis, parts of leaf, equations, and more
| Question | Answer |
|---|---|
| Cuticle | reduces water loss |
| Upper Epidermis | supports; clear to let light through |
| Palisades Layer | main photosynthetic tissue |
| Spongy Layer | contains air spaces for diffusion of c02 in, 02 out |
| Stomate | opening that lets co2 in and 02 out |
| Guard Cell | closes stomate to reduce water loss |
| Xylem | transports water from roots to leaves |
| Phloem | transports food leaves to roots |
| Vein | combined xylem and phloem |
| Lower Epidermis | contains stomates |
| What is the general equation of photosynthesis? | co2 + h20 -------> c6h1206 + 02 |
| what are the 2 sets of reactions that take place in photosynthesis | light dependent and light independent |
| light dependent reaction | (aka photochemical)uses sunlight to break water free electrons to make ATP and NADPH |
| light independent reaction | (ask carbon fixation) uses NADPH, ATP from light reactions to make glucose |
| What is photolysis? | breaking down of water with suns energy |
| When in the chloroplast does photolysis occur? | thylakoid |
| What are the reactants and products of photolysis? | reactants: water, sun products: H+, o2, e- |
| What is carbon fixation? (calvin cycle) | co2 ---> C6H12O6 |
| Where does carbon fixation occur? | stroma |
| What are the reactants and products of carbon fixation? | reactants: CO2 products: glucose |
| What is chlorophyll? | pigment that absorbs light and transfers energy |
| What wavelengths (colors) of light does photosynthesis occur at the quickest rate? | blue, red, violet |
