Kingdom Plantae Discover education video 1 Plant Characteristics Multicellular and eukaryotic Reproduce sexually and asexually Autotrophic (photosynthesis) Surrounded by cell walls containing cellulose (polysaccharide) Store reserve food as amylose (starch) Examples include familiar organisms such as trees, flowers, herbs, bushes, grasses, vines, ferns, mosses, and green algae. 2 Have chloroplasts containing chlorophyll Most are terrestrial (land based) although there are exceptions Plant Divisions 4 Taxonomy Land plants are divided into two groups based on the presence or absence of an internal transport system for water and dissolved materials This is called a Vascular System Vascular Bundles 6 Video Classification of plants Nonvascular: No vessels No roots No stems No leaves Ex: Mosses and liverworts Require a constantly moist environment Vascular: Have vessels to transport food and water They have roots, stems or leaves Ex: grass, corn, trees, flowers, bushes Main Parts of Vascular Plants: Shoots -Found above ground -Have leaves attached - Photosynthetic part of plant Roots -Found below ground -Absorb water & minerals -Anchor the plant 10 Vascular Plants Subdivided into two groups: Seedless Seed-bearing Club Moss 11 Seedless plants (e.g., ferns) have a vascular system but reproduce using spores. Seed plants reproduce using seeds Seedless Vascular Plants Whisk ferns Horsetails 15 Seed bearing: 16 Why We Can’t do Without Plants! Produce oxygen for the atmosphere Capture energy through photosynthesis so they can be used for food Provide homes and food for many organisms Prevent erosion 17 More Reasons We Can’t do Without Plants! Produce lumber for building Produce wood pulp for paper products Source of many medicines Ornamental and shade for yards Fibers such as cotton for fabric Dyes 18 More videos from Discovery Education Plant cells have different roles The survival of plants Now try the crossword!
