Algae - Aquatic Plants &

These plants are not attached to the bottom at all. They drift with the current, absorbing nutrients directly through roots hanging in the water. Examples include duckweed and water hyacinth. The World of Algae

Through photosynthesis, they release dissolved oxygen into the water, which is essential for fish and invertebrates.

These organisms act as natural filters, absorbing excess nutrients like nitrogen and phosphorus, which helps prevent toxic water conditions. Aquatic Plants & Algae

These live entirely underwater. They often have limp stems because the water provides the necessary buoyancy and support. Pondweeds and coontail are frequently found in this category.

Are you focusing on a (e.g., the Amazon, local ponds, or coral reefs)? These plants are not attached to the bottom at all

These invisible giants produce roughly 50% of the Earth's oxygen. They are the primary producers that feed everything from tiny zooplankton to blue whales. Ecological Importance

Most closely related to land plants, these are common in freshwater. They range from the "pond scum" seen on surfaces to complex branched structures. The World of Algae Through photosynthesis, they release

Algae are classified primarily by their photosynthetic pigments, which give them distinct colors and allow them to thrive at different depths:
