1. Introduction to Seaweeds Explorers Education Programme: www.explorers.ie

2. Seaweed is...... A marine algae. It has a challenging life on the shore where it has to survive in salty water, crashing waves, tides and exposure to the heat and sun. Seaweed provides an important source of food and protection for a wide variety of marine animals as well as generating life and providing oxygen in the water.

5. Wonderful Seaweed Instead of leaves seaweeds have a blade or series of branching fronds growing from the holdfast. Like leaves from plants, the blades and fronds in seaweed are the photosynthesising or food-producing parts of the plant. Instead of stems seaweeds have stipes which absorbs the shock of the crashing waves and tides. Some seaweed has air-filled bladders that help their blades rise up towards the surface of the water, where they have a better chance of absorbing the sun's energy. Seaweeds also produce a gelatinous substance that minimizes water loss – particularly when the tide is out. Explorers Education Programme: www.explorers.ie
