| CUTICLE | WAXY COVERING WHICH PREVENTS EXCESSIVE WATER LOSS |
| STOMATA | OPENINGS IN EPIDERMIS WHICH ALLOW CARBON DIOXIDE AND OXYGEN TO ENTER OR EXIT. |
| GUARD CELLS | REGULATE THE OPENING AND THE CLOSING OF STOMATA |
| PALISADE LAYER | MADE UP OF LONG CELLS WITH MANY CHLOROPLASTS |
| SPONGY LAYER | CONTAINS MANY AIR SPACES FOR EXCHANGE OF GASES. |
| VEINS | CONTAIN XYLEM AND PHLOEM WHICH CARRY MATERIALS THROUGH THE PLANT. |
| TRANSPIRATION | LOSS OF WATER FROM LEAVES |
| XYLEM | TRANSPORTS WATER THROUGH THE PLANT |
| PHLOEM | TRANSPORT FOOD THROUGH THE PLANT |
| EDIBLE ROOTS | CARROT, BEET |
| EDIBLE STEMS | ONION, GARLIC, POTATO, ASPARAGUS |
| EDIBLE LEAVES | SPINACH, CABBAGE, LETTUCE |
| EDIBLE FLOWERS | BROCCOLI, CAULIFLOWER |
| EDIBLE OVARIES | CUCUMBER, EGGPLANT, SQUASH |
| FUNCTION OF LEAF EPIDERMIS | PROTECT THE CELLS INSIDE THE LEAF |
| ROLE OF LEAVES IN A PLANT | CARRY OUT PHOTOSYNTHESIS |
| GAS THAT ENTERS THE STOMATA DURING PHOTOSYNTHESIS | CARBON DIOXIDE |
| GASES THAT LEAVE THE STOMATA DURING PHOTOSYNTHESIS | OXYGEN AND WATER VAPOR |
| PARTS OF A LEAF THAT CONTAIN CHLOROPLASTS | PALISADE LAYER, SPONGY LAYER, GUARD CELLS |
