All of us do know that plants evolved from green algae, but the algae is from fresh water or oceans?

The origin of plants can be traced back to about 500 million years ago. They evolved from single-celled algae in aquatic environments, such as fresh water or oceans. Over time, they developed the ability to live on land and eventually diversified into the wide variety of plants we see today.
There is still debate among scientists about where plants first evolved, but evidence suggests that they likely originated in fresh water. This is because the earliest known land plants had adaptations for living in a wet, aquatic environment, such as the ability to absorb water and nutrients through their tissues.
Plants evolved a number of adaptations to survive on land, including developing a waxy outer layer to prevent water loss, developing root systems to anchor themselves in soil and absorb water and nutrients, and developing specialized structures for reproduction and dispersal of offspring.
There are several lines of evidence that support the idea that plants evolved from aquatic ancestors. Fossil evidence shows that the earliest known plants were found in aquatic environments. Additionally, the cell structure and reproductive methods of plants are similar to those of aquatic algae. Genetic analysis also supports the idea of a common ancestor between plants and algae.
The evolution of plants had a significant impact on the evolution of other organisms. For example, the development of land plants provided a source of food and shelter for animals, which led to the diversification of animal species. Plants also played a crucial role in the oxygenation of the Earth's atmosphere, making it possible for other organisms to thrive. Additionally, the relationships between plants and other organisms, such as pollinators, have co-evolved over time.
