1. Marine Plants
Kingdom Plantae

2. Multicellular Algae Structure Lack leaves, stems and roots
Body is called Thallus
Blade is the flat leaf like structure
Pneumatocyst are the gas-filled bladders that help it float
Stipe is the stem like portion
Holdfast anchors the plant to the bottom

3. All multicellular algae undergo photosynthesis Lack vascular tissue
Leaves are different from land plants
Economic importance
Food, starch-like chemicals, emulsifier in dairy foods
Reproduction
Mostly asexual
Fragments
Spores
Sexual
Alternation of generations
Male/ female
