Plant Structure Growth
Show Answers:

  1. There basic organs of plants
    Roots, Stems and Leaves
  2. Two basic parts of plants
    Roots and Shoots
  3. Three basic tissue of plants
    Dermal, Ground, Vascular
  4. Functions of Shoots and Roots
    • Shoots-gather light and CO2 from
    • the air
    • Roots-take up water and nutrients and help anchor the plant
  5. Plants inhibit what two worlds?
    Atmosphere above ground and soil below the surface of the earth
  6. Three characteristics of Monocots
    • Monocots are herbaceous
    • Do not produce secondary growth
    • Most do not produce wood
  7. What is the difference between Monocots and Dicots?
    The number of seeds
  8. Characteristics of Simple Leaves
    • Primary organ that photosynthesizes
    • Flat surface
  9. Characteristics of Modified Leaves
    • Protection Ex: Cactus spine
    • Nutrient Storage Ex: Onion 
    • Water Storage Ex: Succulents 
    • Climbing Ex: Tendrils
  10. Characteristics of Stems
    • Provides structure and support 
    • Consists of nodes and internodes 
    • Consists of apical (terminal) bud
  11. What are nodes and internodes?
    • Nodes are area where leaves attach
    • Internodes are segments between nodes
  12. Characteristics of Modified Stems
    • Water Storage Ex: Cactus stem 
    • Asexual Reproduction
    • Food Storage 
    • Protection
  13. Characteristics of Roots
    • Roots absorb and conduct water and nutrients to shoots
    • Store products made in shoot
    • Can also be morphologically
    • diverse
    • Tap root – primary root that runs
    • deep vertically 
    • Lateral roots- branching roots
    • run horizontally from primary root
    • Fibrous- many small roots forming
    • a mat which spreads out vertically and laterally in the soil
  14. Characteristics of Modified Roots
    • Specialized for gas exchange 
    • Storage Roots
  15. What is Dermal Tissue?
    • (skin)- a single layer of cells covers and protects the plant body
    • Forms barrier between plant and environment 
    • Prevents water loss and disease
  16. What is Ground Tissue?
    • Makes up the majority of the plant body
    • Function: photosynthesis and storage
    • Responsible for Photosynthesis, CarbohydrateStorage Synthesis and storage of hormones, pigments, and toxins that deter predators
  17. What is Vascular Tissue?
    • Vascular tissue runs through ground tissue
    • Support tissue and transport of water, nutrients, and photosynthetic products
  18. What are the three components of Ground Tissue?
    Parenchyma, Collenchyma, and Sclerenchyma cells
