1. Marine Biology
Drill:
Explain how floatation in plankton is important for their survival.
Outcome:
List and label the types of marine plants that exist.
Explain the importance of stability in an ecosystem, specifically the kelp beds in California.
Agenda:
Review plankton
Discuss Marine Plants (Kelp Forests)
Review

2. Marine Plants There are four categories of marine plants: marine algae
sea grasses
marsh grass
mangroves
Marine Plants provide habitats for many marine creatures including shrimp, bivalves, fish, plankton, and other small organisms.

3. Microscopic Algae There are three types of algae that exist:
Green Algae
Brown Algae
Red Algae

4. Sea Grasses
Seagrasses are grass-like flowering plants that live completely submerged in marine and estuarine waters.
Seagrasses require lots of light, so the depths at which they occur in the ocean are limited by light availability.

5. Sea Grasses

6. Marsh Grasses
Marsh grasses are soft- stem plants that have adapted to thrive in soil that is continuously saturated.
Marshes can live in either saltwater or freshwater wetlands.

8. Mangrove
Mangrove trees are able to survive in high salt concentrations by excluding some salt at the root level.
Mangrove trees can tolerate salt in quantities that would kill other plants because of their raised roots.

11. Marine Kelp (Brown Algae)
Type of brown algae
Grows from 10 inches up to 2 feet a day
Structure
Blade: absorbs light to photosynthesize
Gas Bubble: helps structure to float
Stipe: Stem like structure, support
Holdfast: Root like structure that holds the kelp in place
