  1. Plant Structure & FunctionCh. 29.2, 29.3, 29.4, 30.2

  2. Plant Vocab Non-Vascular: lacking xylem and phloem Vascular: have xylem and phloem Gymnosperm: pine trees Angiosperm: flowering plants

  3. Comparing Monocots & Dicots (Angiosperms)

  4. Root Functions (29.2) Major Functions: anchor plant to soil, absorb and transport water and nutrients, and store water and organic compounds. Growth: 1. Primary- lengthening and elongation of the root. 2. Secondary- widening of the root and expansion of root structures.

  5. Types of Roots 1. Tap root: if the primary root becomes the longest root. 2. Fibrous roots: Numerous small roots develop and branch out. 3. Adventitious roots: specialized roots that grow from uncommon places of the plant. Root hairs: increase surface area to increase its ability to absorb water & minerals from soil

  6. Root Structures Monocot Dicot

  7. Stem Functions (29.3) Function: -transportation of water & nutrients -storage of nutrients -support of leaves Translocation refers to the movement of sugars through the plant in the phloem. Pressure Flow Hypothesis explains how sugar flows in the phloem with the help of osmosis. Transport of water and mineral nutrients occurs through the xylem. Transpiration is the process in which plants lose water when obtaining carbon dioxide for photosynthesis. The cohesion-tension theory explains on water flows against gravity from the roots up through the stem to the leaves.

  8. Types of Stems • Stolons • Tubers • Fleshy

  9. Stem Structures Monocot Dicot

  10. Leaf Function (29.4) Function: primary site of photosynthesis.

  11. Leaf Vein Patterns: Monocot Dicot

  12. Leaf Structures:

  13. Flower Functions (30.2) Function: attract animals for the spread of pollen which leads to reproduction.

  14. Flower Petal Patterns Monocot Dicot

  15. Flower Structures: Lily flower (monocot): A-anther B-filament A+B = stamen (male) C-stigma D-style E-ovary C+D+E = pistil (female) petal sepal pollen
