1. Plant Systems

2. Two types of systems:  Root System  Shoot System

3.  Anchorage  Keeps plant in the soil  Holds stem in place  Absorption  water  dissolved minerals  Storage  Starch and nutrients

4.  Large long primary root  Strong anchoring system  Specialized to store water and nutrients

5.  Many small roots that branch  Increases surface area  Better absorption, less structural support

6. Shoot System Function Main functions:  Conduct photosynthesis  Produce flowers for sexual reproduction Main components:  Stem  Leaf  Flower

7.  Supports branches, leaves and flowers  Transport of water and nutrients through vascular tissue  Some are specialized for food storage. Ex) sugar cane, potatoes, onions

8.  Main function: Photosynthesis  Parts of the Leaf:  Epidermis  Cuticle  Guard Cells & Stomata  Palisade cells  Spongy Layer  Vascular Tissue

9.  Outer layers of cells  Cuticle is waxy coating on exterior of leaf  Protects interior, water proofing and blocks passage of gases http://www.goldiesroom.org/Multimedia/Bio_Images/05%20Nutrition/15a%20Cross%20Section%20of%20a%20Leaf.jpg

10.  Pore-like openings in the plant’s epidermis  Opening size controlled by two guard cells  permits gas exchange with environment.

12.  Contains many chloroplast for photosynthesis  Cells stand tall and upright

13.  Where water is stored  Location of vascular tissues

14.  Specialized structures developed for sexual reproduction known as pollination  Can contain both male and female reproductive structures in the same flower

15.  Male reproductive organ: stamen  Pollen (male gametes) produced on anther  Female reproductive organ: pistil  Ovule (female gametes) produced in ovary  Pollination involves the pollen traveling down the style into the ovary for fertilization http://www.exploringnature.org/graphics/teaching_aids/flower_parts_color72.jpg
