| What cell walls contain which is a chemical compound that plants can make out of sugar. | cellulose |
| inside the epidermis, there are several layers of large, loosely packed cells that store food and this food can be used by other cells by the plant | cortex |
| inside the cortex theses are tubelike cells that form vessels that carry water and minerals. | xylem cells |
| Tissue that moves food from leaves and stems | phloem |
| have tubelike structures that carry water, nutrients, and other substances throughout the plant ex. trees, sunflowers, club moss,ferns | vascular plants |
| do NOT have tubelike structures and use other ways to move water and substances needed ex. liverwort, moss, hornworts | nonvascular plants |
| uses of of seedless vascular plants | landscaping, gardening, burns, fevers, even dandruff |
| Held in place by rootlike filaments | rhizoids |
| The first plants to grow in new environments | pioneer species |
| small pores in the leaf surface | stomata |
| guard cells | cells that open and close stomata |
| tissue of tubular vessels that move water | Xylem |
| tissue that produces new xylem and phloem cells | Cambium |
| vascular plants that produce seeds that are not protected by fruit | Gymnosperms |
| is a vascular plant that flowers and producers fruits with one or more seeds, such as peaches | angiosperm |
| Many plant cells contain red, yellow, or orange pigments that are also used for photosynthesis | carotenoids |
| have one cotyledon used for food storage inside their seeds | monocots |
| have two cotyledon inside their seeds | dicots |
