| Epidermis | the skin formed from dermal tissues in the non woody parts of a plant |
| Cork | the dermal tissue on woody stems and roots consists of several layers of dead cells |
| Vessels | Gnetophytes and flowering plants also have a second type of xylem cell, which makes up conducting strands |
| Sieve tubes | the conducting strands in phloem |
| Cortex | the ground tissue surrounding the vascular tissue |
| Root hair | the epidermal cells just behind a root tip slender projections of a cell membrane that greatly increase the surface area of a root and its ability to absorb water. |
| root cap | a mass of cells that cover and protects the actively growing root tip |
| Herbaceous plant | a plant with stems that are flexible and usually green |
| Vascular bundles | the stems of herbaceous plants contain bundles of xylem and phloem |
| Pith | the ground tissue inside the vascular bundles |
| Heartwood | the wood in the center of a mature stem or tree trunk where the xylem no longer conducts water |
| Sapwood | lies outside the heartwood, contains vessel cells that can conduct water |
| Petiole | most leaves have a flattened portion, called the blade, that is often attached to a stem by a stalk |
| Mesophyll | the ground tissues in leaves that have cells that are packed with chloroplast |
| Transpiration | loss of water vapor from a plant |
| Source | refers to a part of a plant that provides organic compounds for other parts of the plant |
| Sink | refers to a part of a plant that organic compounds are delivered to |
| Translocation | the movement of organic compounds within a plant from a source to a sink |
