| Dermal Tissue | tissue made of cells that protect the outer surfaces of plants- skin cells of the plant |
| Ground Tissue | tissue made of the cells that are providing the functional purpose of the part of the plant where they are found: storage cells in the root, woody structural cells in the stem, photosynthesizing cells in leaves |
| Vascular Tissue | tissue made of cells that are designed to move water and nutrients around the plant. |
| Xylem | part of the vascular system which carries water throughout the plant from the root system |
| Phloem | part of the vascular system which carries concentrated solution of nutrients to cells of the plant. |
| Tap root system | main root down into the soil which can reach deeply into the ground,smaller roots allow for increased surface area for absorption. |
| fibrous root system | numerous smaller roots to provide a large surface area for absorption |
| symbiotic fungi | assist the plant in collecting moisture from the soil in exchange for nutrients from the plant |
| Rhizobia nodules | bacterial colonies feeding on nutrients from the plant while providing the plant with nitrogen based compounds coming from atmospheric nitrogen gas. |
| Primary growth of the plant | increase in the length of the plant's stem or height |
| Secondary growth of the plant | increase in the diameter of the stem or trunk of a tree. |
| Vascular system of trees | Xylem is located inside of the phloem in the outer ring of the stem |
| Vascular system of monocots | Xylem tubes are located throughout the stem while phloem forms the outermost ring of the stem |
| Vascular system of dicots | xylem is located inside of phloem in bundles which form a ring in the middle of the stem |
| purpose of the plant stem | provides vertical structure, allows the plant to compete for sunlight. contains vascular tissue to transfer water and nutrients throughout the plant. |
| purpose of the leaf | absorb sunlight and produce organic molecules |
| water conservation in the leaf | Dermal tissue in the plant provides protection against the elements, a waterproof barrier to prevent loss, Pores called Stomata can open to let gasses into the leaf or remain closed to reduce water loss through transpiration. |
| mesophyll layer of the leaf | contains the cells which are doing photosynthesis |
| palisade mespphyll | layer of densely packed photosynthesizing cells |
| spongy mesophyll | cells loosely packed as well as volume for gasses to be exchanged between the photosynthesizing cells |
| know the structure of the leaf | you will need to label a diagram of the leaf |
