2. Seaweed
Trees on land play a very important role on the earth.This is because
they use carbon dioxide, a byproduct of multiple chemical processes, to
turn this waste gas back into oxygen. In the same way water plants use
the absorbed carbon dioxide present in water and give off oxygen and
allow fish to breathe. Some species also absorb waste products of
other animals and recycle them for nutrition.

The term seaweed is loosely used to refer to all marine plants.
However there are several types of plants that live in water such as
lichens, sponges, and red/brown/green algae. Seaweed does not have
roots like terrestrial plants and trees because they do not need to
absorb water and nutrition from the soil. Instead they absorb it
through pores on their surface. They
do have growth at the bottom that
look very similar to roots but are
used only to attach themselves to the
ground and prevent them from being
carried away by currents.

4. Spores stick to
rocks and grow.
The spores
turn into young
sea plants.
The young plants
grow big
Seaweeds do not produce flowers like their land cousins. Instead they
reproduce using tiny particles known as spores. When a spore settles
onto a rock, it will attach itself and begin to grow if the conditions are
favourable.

5. Not only does seaweed help the natural cycle of the oceans but they
also provide shelter and breeding grounds for the thousands of fish that
live with them.
