Presentation on theme: "Staying “afloat” in air? Strong support tissue, lignin"— Presentation transcript:
1 Staying “afloat” in air? Strong support tissue, lignin Describe four challenges to plants living on land and how the plants have adaptedHow to Get Nutrients from land and air? Shoots (stems and leaves) and roots.Staying “afloat” in air? Strong support tissue, lignin
2 Describe four challenges to plants living on land and how the plants have adapted. Retaining moisture. Waxy cuticle and stomata (pores) surrounded by guard cellsReproducing in air – internal fertilization and embryo development.Seeds enclosed in protective “jackets”Pollen so sperm won’t dry out
3 Identify the four major groups of plants and their major characteristics.
4 Ferns, horsetails, club mosses Describe the characteristics of a pteridophyte, and give three examples of these plants.Vascular plants(have xylem and phloem) that do not produce seeds, they reproduce by sporesFerns, horsetails, club mosses
5 What three structures do all vascular plants have? RootsStemsLeaves
6 List the four main groups of gymnosperms. GinkosConifersCycadsGnetophytes
7 What does a “naked” seed mean? Not enclosed in an ovary
8 Flowers – attract pollinators Describe 2 unique features of angiosperms and how these features help the plants.Flowers – attract pollinatorsFruit – protection of seeds, nutrition of seeds, helps with dispersal
9 Characterize the two largest evolutionary branches of angiosperms Characterize the two largest evolutionary branches of angiosperms. Describe their differences.MonocotDicotSingle cotyledonParallel veins in leavesDouble cotyledonVeined leaves
10 Food Animal Food Clothing Fuel Ornamental Describe ways that humans depend on angiosperms. Name one way you utilized an angiosperm today.FoodAnimal FoodClothingFuelOrnamental
12 Relate the structures of a flower to their reproductive functions, and indicate whether the structure is male, female, or neither.
13 Describe root and shoot structures and functions Vascular tissue, transport of nutrients and wastes, photosynthesis.
14 What are the two functions of vascular tissue? TransportStructural support
15 Describe three main plant tissues systems Dermal Tissue: Outer covering or “skin” of the plantVascular Tissue: transports water, mineral nutrients, and organic molecules between roots and shoots (ex. xylem and phloem)Ground Tissue: tissue in-between dermal and vascular tissue that functions in photosynthesis, storage and support.
16 Describe the two types of vascular tissue and their specific functions XylemPhloemTransports water and dissolved minerals upTransports food from leaves to parts of plants that photosynthesize
17 Trace the path of nitrogen from the atmosphere to a plant’s roots
18 Explain how water loss from a plant is regulated Waxy cuticleStomata = microscopic pores found on the under side of leaves that open and closeStomataClosedStomataOpen
