| Reproductive plant organs | The parts of a plant (such as flowers, fruits, and seeds) involved in reproduction |
| Undifferentiated cells | Cells that have not specialized in any particular function |
| Xylem | Nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves |
| Phloem | Living vascular tissue that carries sugar and organic substances throughout a plant |
| Leaf mosaic | The arrangement of leaves on the stem of a plant |
| Leaf margin | The characteristics of the leaf edge |
| Deciduous plant | A plant that loses its leaves for winter |
| Girdling | The process of cutting away a ring of inner and outer bark all the way around a tree trunk |
| Alternation of generations | A life cycle in which there is both a multicellular diploid form and a multicellular haploid form |
| Dominant generation | In alternation of generations, the generation that occupies the largest portion of the life cycle |
| Pollen | A fine dust that contains the sperm of seed-producing plants |
| Cotyledon | A "seed leaf" which develops as a part of the seed- it provides nutrients to the developing seedlings and eventually becomes the first leaf of the plant |
