| upper/lower epidermis | produce cuticle; protects inner tissues |
| cuticle | thin waxy covering; prevents water loss in leaf |
| palisade mesophyll cells | a layer of tall, columbar mesophyll cells found under the upper epidermis; absorb light that enters the leaf |
| bundle sheath cells | cells that make up the outer layer of the vein; play role in C4 photosynthesis |
| xylem | vascular tissue; circulates water and dissolved minerals; support plants |
| phloem | vascular tissue; carries products of photosynthesis away from leaf |
| spongy mesophyll cells | a loose tissue with many air spaces between its cells; stores CO2 and O2 |
| stoma/stomata | porelike openings in the epidermis that allow carbon dioxide and oxygen to diffuse into/out of the leaf |
