Document Summary
Main characteristics of kingdom plantae: eukaryotic, multicellular, photosynthetic autotrophs, varied and complex life cycles, cell walls made of cellulose, food reserve stored as starch or oils. The life cycle in plants involve: alternation of generations. Land plants came from algae, so they share common traits however there are some major differences. >xylem and phloem: part of the plants vascular tissue system, plants with this trait are vascular plants, vessels that transport water, minerals, nutrients, sugar, and hormones. >lignin: material that is added to the cell walls of woody plants. Increases stiffness of the cells and allows better support for leaves. >cuticle: layer of waxy material on the epidermal layer, helps prevent water loss or desiccation. >stomata (stoma singular: opening in the surface (usually underside) of a leaf, allow gas exchange, but limit water loss. Two main categories of land plants: nonvascular (bryophytes, vascular (tracheophytes) Nonvascular plants: liverworts (hepatophyta, hornworts (anthocerotophyta, mosses (bryophyta)
