Marine plants are primarily found in oceans and other saltwater environments. They include various types of organisms, such as seaweeds, seagrasses, and phytoplankton. These plants play a crucial role in marine ecosystems by providing oxygen, serving as food for marine animals, and helping to stabilize the ocean floor. Unlike terrestrial plants, marine plants are adapted to life in saltwater. They have specialized structures to absorb nutrients and cope with the saline environment. Marine plants also contribute to carbon cycling and can help mitigate climate change by absorbing carbon dioxide from the atmosphere.
