| Question | Answer |
|---|---|
| xylem | vascular tissue that transports WATER AND MINERALS through a plant |

| roots | supply plants with water and dissolved minerals |
| roots | hold plants securely in the soil |
| roots | store surplus food made during photosynthesis |
| roots hairs | cells of the epidermis that extend from the root |
| root cap | group of cells that produces a slimy substance |
| taproot | root system with one main root |
| epidermis | layer of cells that covers root surfaces |
| monocots | plants that usually have fibrous roots |
| root tip | structure protected by the root cap |
| surface area | what root hairs increase |
| fibrous root | root system in which roots are usually the same size |
| xylem | carries water and minerals from the roots to the leaves |
| phloem | carries food to plant parts |
| herbaceous | stems that are soft, thin and flexible |
| woody stem | rigid stems made of wood and bark |
| leaves | they make food for the plant |
| cuticle | structure that prevents water loss from the leaf |
| guard cells | cells that open and close the stomata |
| palisade layer | layer of cells that contains many chloroplasts |
| epidermis | a single layer of cells beneath the cuticle |
