| vascular plants | contain tubelike cells which transport water, minerals, and nutrients , most reproduce by seeds |
| nonvascular plants | no internal transport system, materieals travel by diffusion reproduce by spores |
| vascular scientific name | tracheophyces |
| nonvascular scientific name | bryophytes |
| gymnosperms | conifers or evergreens, conebearing, seeds produced in cone |
| angiosperms | 2 groups |
| monocats | 1 cotyledon, leaves have parallel venation vascular bundles scattered, flower parts in multipes of 3 |
| dicots | 2 cotyledons, netted leaf, vascular bundles arranged in flower parts in multipes of 4 or 5 |
| cotyledon | supplies new plant with food structure in seed, keeps seed alive |
| epidermis | outler layer protects against invasion of parasites |
| cuticle | waxy transparent layer keeps from rapid dehydration |
| xylem | carries water and minerals |
| phloem | carry food |
| ground tissue | cushions and protects vascular bundles storage of food and water |
| what makes up ground tissue | parenthyma cells |
| meristematic tissur | cells which constantly divide there for causing growth |
| primary growth | lentgh buds, root tip |
| secondary growth | diamiter with vascular cambum |
| roots | storage of water and food absorbes water and minerals |
| stems | support transport |
| leaves | photosynthesis make food |
| flowers | reproductive organ produce seeds |
| annuals | live 1 year sprout, grow, reproduce and die in 1 year |
| biennials | lives 2 years 1 year roots and seeds, 2 flowers and seeds, develop large storage roots heroaceous, ex potato |
| perennials | live many years, produces flowers and seeds each year woody plants hard stemmed grasses many wild flowers, tulips |
| petiole | small stalk attaches leaf to stem |
| blade | flat part of leaf normally green |
| veins | run through leaf blade carry food and minerals and water |
| leaflet | make up 1 leaf branched |
| simple leaf | not divided into seperate parts |
| compound leaf | leaflets divided into seperate parts |
