| photosynthesis | process by which plants make food |
| photosynthesis formula | water+carbon dioxide+sunlight energy -> sugar + oxygen |
| chlorophyll | green pigment absorbs energy from sunlight |
| chloroplasts | structures containing chlorophyll where photosynthesis takes place |
| root | absorbs water and minerals and anchors plant in ground. |
| Stem | allow movement of materials through plant via the xylem and phloem |
| xylem | transports water and minerals up from the root |
| phloem | transports food from leaves to all parts of plant |
| leaf | plants major organ for making food. |
| epidermis | thin layer of cells that protects the leaf |
| cuticle | waxy coating that keeps leaf from drying out |
| palisade layer | layer of leaf where most food is made |
| stomates | small openings on bottom of leaf where air and gases move in and out |
| guard cells | cells on side of stomata to open and close it |
| fruit | holds and protects the seed |
| nonvascular plants | lacks xylem, phloem, roots, stem, and leaves |
| nonvascular plants | reproduce by spores |
| vascular plants | have roots, stems and leaves |
| Xylem and phloem | make up vascular plants vascular system |
| Seedless vascular plants | reproduce through spores |
| Gymnosperms | seeds that don't have protective covering |
| angiosperms | seed is enclosed and protected in fruit |
