| Glucose | The fuel a plant produces through photosynthesis. |
| Autotrophs | Plants that are able to produce their own food supply. |
| Heterotrophs | Living things that depend upon other living things as food. |
| Chloroplasts | The cells of plants where photosynthesis takes place. |
| Cell walls | The part of a plant cell that gives it strength and animal cells do not have. |
| Cellulose | Long chains of glucose molecules, that make up the cell wall of plant cells. |
| Taxonomists divide all plants into two groups based upon the presence of what type of tissue? | Vascular |
| Xylem | Vascular tissue that carries water in the plant. |
| Phloem | Vascular tissue that carries food, fuel. or glucose around the plant. |
| Divisions | The plant kingdom's first level of classifications, unlike the animal kingdom's, which are phyla. |
| Bryophyta | A single division of plants in the non-vascular division. |
| The Bryophyta Division is broken down into 3 classes that are: | 1. Class Hepaticae, which are liverworts 2. Class Anthocerotae, which are hornworts 3. Class Musci, which are mosses |
| Division Psilophyta | Has fern-like leaves and the most common member is the whisk fern. |

| Perfect Flowers | Those flowers that contain both male & female structures present. |
| Imperfect Flowers | Those flowers that contain only one sex or reproductive structure. |
| Stamen | The male part of a flower. |
| The two parts of the Stamen are: | 1. Filament, which is stem-like 2. Anther, which is pollen producing |
| Pistil | The female part of a flower. |
| The two parts of the Pistil are: | 1. Style, which is stem-like 2. Stigma, which is the sticky top |
| Pollen carries 2 types of cells that form | 1. pollen tubes 2. sperm cells |
| Pollen Tube | Allows the sperm cells to join the ovules present in the ovary of the flower. |
