Algae

Algae lack leaves, roots, flowers, and other organ structures that characterise higher plants. They are usually found in damp places or bodies of water and are common in terrestrial as well as aquatic environments.

However, terrestrial algae are usually rather inconspicuous but are far more common in moist, tropical regions because algae lack vascular tissues and other adaptations to live on land. Seaweeds are algae which grow in shallow marine waters.
