Las algas

Algae are vital aquatic organisms similar to plants but without roots, stems, or leaves. They perform photosynthesis using chlorophyll and come in various shapes and sizes, from microscopic forms to large seaweeds like kelp. Kelp forests are crucial marine ecosystems. Algae also form symbiotic relationships, such as with coral, providing mutual benefits. They are sensitive indicators of climate change, highlighting their importance in global ecosystems.
