1 Plants SC.912.L.14.7 Relate the structure of each of the major plant organs and tissues to physiological processes.

2 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Plant Organs Roots: anchor, absorb water, store food Stems: support, transport Leaves: photosynthesis, produces food Flowers, Fruits, Cones: reproduction

3 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Plant Tissues Meristematic: regions of rapidly dividing cells Ground: consist of parenchyma, sclerenchyma, and collenchyma cells that have diverse functions Dermal: makes up outer covering of the plant Vascular: xylem (transports water), phloem (transports food)

4 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Other Structures Cambium: meristematic tissues that run the length of the roots and stems and produces new cells for growth Guard Cells: pair of cells that open and close a plant s stomata to allow gas exchange and transpiration Phloem: transport of nutrients Seed: reproductive structure of some vascular plants Stomata: openings on the bottom of a leaf that allow gas exchange and transpiration Xylem: transport of water

5 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. You must know how each tissue and organs helps the plant to carry out the following processes: Photosynthesis Cellular Respiration Transpiration (evaporation of water from leaves) Growth Reproduction

6 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Photosynthesis: carried out in the chloroplasts; dermal tissue contains stomata (pores in leaves which allow gases and water in and out)

7 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.

8 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Cellular Respiration: carried out in mitochondria in cells found throughout the plant

9 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Transpiration: carried out in the leaves; dermal tissue contains stomata surround by guard cells which open and close to allow water to evaporate from the leaves

10 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Growth: meristematic tissue is the region of growth in plants; cambium (found in the stem) contains meristematic cells as well as root cap Reproduction: flowers, fruits, and cones contain reproductive organs for different kinds of plants

11 1. Students will explain how the structures of plant tissues and organs are directly related to their roles in physiological processes. Reproduction In Plants: Spore Producing Plants: nonvascular, produce spores, remain small, absorb water through osmosis, live in moist environments Vascular Plants: some produce spores, but most use flowers, fruits, or cones to reproduce, contain vascular tissues (xylem and phloem) Gymnosperms: cone-bearing Angiosperms: flowers and fruits

12 Classification SC.912.L.15.6 Discuss distinguishing characteristics of the domains and kingdoms of living organisms.

13 1. Students will classify organisms based on distinguishing characteristics of the domains/kingdoms of organisms,

14 1. Students will classify organisms based on distinguishing characteristics of the domains/kingdoms of organisms. Three Domains: Archaea PROKARYOTE, unicellular, autotroph or heterotroph Bacteria (Eubacteria) PROKARYOTE, unicellular, autotroph or heterotroph Eukarya - EUKARYOTE

15

16 1. Students will classify organisms based on distinguishing characteristics of the domains/kingdoms of organisms. Four Kingdoms Under Domain Eukarya: Plant cell walls w/ cellulose, multicellular, autotroph Animal no cell walls, multicellular, heterotroph Fungi cell walls w/ chitin, multicellular, heterotroph Protist some have cell walls, unicellular and multicellular, autotroph or heterotroph

17

18

19 2. Students will identify and describe how organisms are classified based on evolutionary relationships and reasons for changes. Evolutionary relationships are shown in phylogenetic trees (cladograms) The closer the organisms are, the more closely related they are and the more DNA they share!
