What makes a plant cell? - cell walls most have chlorophyll something resembling roots to hold them in eukaryotic cells PLANT KINGDOM Bryophytes Tracheophytes Bryophytes found near H20 and absorb water because it has only a few cells thick vascular = tube like structure to transport nutrients grow from spores seedless nonvascular Example: moss seedless vascular Example: ferns Tracheophytes Seed plants- have roots, stem, leaves, and vascular tissue seed is reproductive part of a plant that contains plant embryo and stored food 2 Types of seed plants Gymnosperm Angiosperm Gymnosperm - vascular plants that produce seeds on scales of female cones - (naked seed) not protected by a fruit - Do not produce flowers - Most leaves are needle-like - Include: conifers, cycads, gingkoes and gnetophytes Most produce male and female cones on same tree. Angiosperm- seed is enclosed in a fruit - produce flowers Monocot -1 seed leaf Dicot -2 seed leaves Gymnosperms and Angiosperms have same basic structure (roots, stems, and leaves)
