Test Oct. 11
| Question | Answer |
|---|---|
| Function of ATP | high energy molecule- cell gets energy from it |
| Reactants for photosynthesis | Chlorophyll/sunlight, water, carbon dioxide |
| End products of photosynthesis | Glucose, oxygen |
| Chief function of leaves | photosynthesis, respiration |
| Where is the cutin? | outer leaf layer |
| upper epidermis | row of cells under cuticle |
| palisade mesophyll | upper layer of middle cells |
| spongy mesophyll | under palisade mesophyll |
| lower epidermis | row of cells which surround stoma |
| guard cells | pairs of modified cells of the leaf epidermis that control the opening and closing of stomatal pores |
| stoma | release water and oxygen to the air and take in oxygen and carbon dioxide |
| leaf vein | contains xylem and phloem |
| chlorophyll | found in chloroplasts, reflects green and yellow light |
| photolysis | the splitting of water during photosynthesis |
| chemosynthesis | when an autotroph obtains energy from norganic compounds instead of from light. |
| glycolysis | the anaerobic process of splitting glucose and forming two molecules of pyruvic acid |
| aerobic respiration | requires oxygen to break down molecules |
| anaerobic respiration | o not require oxygen to break down molecules |
| fermentation | releases energy without oxygen |
| mesophyll | the photosynthetic tissue of a leaf |
| transpiration | the evaporation of water from stomata |
| autotroph | organisms that make their own food |
| heterotroph | organisms unable to make their own food, they rely on autotrophs as their nutrient and energy source |
