Marine Biology Outcome: Review the importance of plankton in respect to food webs. Gain knowledge on the types of marine plants that exist. Complete worksheets on Marine Plants. Study for next class… start with today… Questions/Comments/Concerns

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.

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

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.

Sea Grasses

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

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.

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 Frond: The blade, gas bubble, and stipe together Holdfast: Root like strutcure that holds the kelp in place
