| Vascular plants have a fundamental unity of structure. | two basic parts: root system, shoot system |
| Vascualar plants have three basic organ types | roots, stems, leaves |
| Vascular plants have three basic tissue types | dermal, ground, vascular |
| Vascular plants have | a root system and a shoot system |
| root system | penetrates the soil/substrate and anchors the plant |
| shoot system | consist of stems and leaves |
| stems | serve as framework and support to position leaves |
| leaves | primary location for photosynthesis |
| meristem | give rise to all other cells of plant |
| primary growth | initiated by apical meristems near tips of roots, shoots |
| ground meristem | produces ground tissue |
| protoderm | produces epidermis |
| procambium | produces primary vascular tissue |
| secondary growth initiated by lateral meristems | internal meristematic cylinders |
| cork cambium | cork cells in bark of woody plants (outer bark |
| vascular cambium | secondary vascular tissue |
| secondary phloem | closest to cork |
| secondary xylem | internal; main component of wood |
| 3 basic plant tissues and cell types | dermal tissue, ground tissue, vascular tissue |
| dermal tissue | epidermis |
