  1. Aquatic Plants

  2. Photosynthesis: Solar Energy + CO2 + H20  C6H12O2 + O2 As CO2 is removed from the water pH increases. Phytoplankton • Single celled • Base of aquatic food web • Oxygen production CO2 + H20  H2CO3 H+ + HCO3- 2H+ + CO3 2-

  3. General Types of Aquatic Macrophytes • Submergent – Plants that grow entirely under water. Most are rooted at the bottom and some may have flowers that extend above the water surface. • Floating-leaved – Plants rooted to the bottom with leaves that float on the water surface. Flowers are normally above water. • Free Floating – Plants not rooted to the bottom and float on the surface. • Emergent – herbaceous or woody plants that have the majority of their vegetative parts above the surface of the water.

  8. Special Adaptations

  9. Wetland Trees Wide at the base Called a buttress Tupelo Cypress Previous Student I won this boat

  10. Benefits of Aquatic Plants • Primary Production • Wildlife Food • Oxygen Production • Shelter • Protection from predation for small fish • Fish Spawning • Several fish attach eggs to aquatic macrophytes • Some fish build nests in plant beds • Water Treatment • Wetland plants are very effective at removing nitrogen and phosphorous from polluted waters

  11. Submerged macrophytes can provide shelter for young fish as well as house an abundant food supply.

  12. Some fish will attach their eggs to aquatic vegetation. Alligators also build nests from vegetation.

  13. Too many plants can sometimes be a bad thing! • Block waterways • Deplete Oxygen
