| Why are plants different from animals | chlorophyll, made their own food and have cell walls |
| vessels | tube like structures that move water with nutrient through a plant |
| vascular plants | plants with vessels |
| nonvascular plants | plant without vessels and obtain water through living in very damp places--algae, mosses, liverworts |
| root hairs | absorb water and nutrients |
| xylem | transport water with nutrients around the plant up |
| phloem | tissue made up of tubelike cells that transport food from the leaves to other parts of the plant |
| cambium | tissue that makes new xylem and phloem cells |
| herbaceous stems | soft and green-tomato, bean, and tulip |
| woody stems | hard and rigid-tree shrubs |
| annual | plant that grows, reproduces and dies within one growing season |
| biennial | produces leaves and food in one year and reproduces and dies within a second year |
| perennial | plant that lives from one growing season to another all woody stem plants |
| petiole | leaf stalk attach the leaf to the stalk |
| epidermis | thin layer of brick-shaped cells that covers all the surfaces of the leaf |
| deciduous | trees that lose their leaves |
| evergreen | lose their leaves but not all at the same time |
| stomata | slitlike openings or pores in a leaf |
| guard cells | surround a stoma and control the size of its opening |
| transpiration | loss of water vapor through stomata of a leaf |
