Anatomy of a Leaf
parts and functions of a generic leaf on a cellular level
| Part | Function |
|---|---|
| waxy cuticle | keeps water inside the leaf |
| upper epidermis | ventral side of leaf |
| palisade mesophyll | lots of chloroplasts for photosynthesis |
| spongy mesophyll | lots of chloroplasts for photosynthesis |
| xylem | allows water to get to the cells |
| vein | functions as a highway for food and reactants in photosynthesis |
| phloem | Food Flows in PHloem |
| lower epidermis | dorsal side of leaf |
| guard cells | allow the stomata to open and close |
| stomata | opening or pore that allows CO2 (carbon dioxide) to get inside the leaf |
| chloroplasts | organelle in which photosynthesis occurs |
| equation for respiration | C6 H12 O6 + 6(O2) => energy (ATP) + 6(H2O + CO2) |
