1 Aquatic Plants

2 Phytoplankton Single celled Base of aquatic food web Oxygen production CO 2 + H 2 0  H 2 CO 3  H + + HCO 3 -  2H + + CO 3 2- As CO 2 is removed from the water pH increases. Solar Energy + CO 2 + H 2 0  C 6 H 12 O 2 + O 2 Photosynthesis:

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.

4 Hydrilla Coontail Parrotfeather Submergent

5 Floating-Leaved Plants

6 Free Floating Plants

7 Emergent Plants

8 Special Adaptations

9 Wetland Trees Wide at the base Called a buttress Cypress Tupelo 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
