| pistil | innermost part of a flower that produces female gametophytes |
| Plantae | kingdom of multicellular photosynthetic autotrophs that have cell walls containing cellulose |
| pollination | transfer of pollen from the male reproductive structure to the female reproductive structure |
| propagation | horticulturists use cuttings, grafting or budding to make copies or produce offspring of seedless plants. |
| seed | embryo of a living plant that is encased in a protective covering and surrounded by a food supply |
| self pollination | Occurs when pollen is transferred from the anthers of a flower to the stigma of either the same flower or a flower on the same plant. |

| tracheid | hollow plant cell in xylem tissue with thick cell walls that resist pressure |
| turgor pressure | the pressure that water molecules exert against the cell wall. |
| vascular bundles | plant stem structure that contains xylem and phloem tissue |
| vascular plants | plants with specialized cells for moving water and nutrients thoughout the plant |
