After over three billion years of evolution in the oceans, multi-cellular life — beginning with green algae, fungi, and plants (liverworts, mosses, ferns, then vascular and flowering plants)-- began adapting to land habitats by creating a new «hypersea,» and adding anomalous shades of green to Earth's coloration more than 472 million years ago (Matt Walker, BBC News, October 12, 2010; and Qiu et al, 1998 — more on the evolution of photosynthetic life and plants on Earth).

Exploiting habitats that are often or mostly out of water required new symbiotic relationships to contain and move water, including the fusion of some fungi and algae to create lichen in communities with bacteria that survive extreme desiccation on land while breaking down rock into soil, and the association of mycorrhizae fungi and the root tissue of new vascular plants — culminating in trees that pump water high into the air — to exchange mineral nutrients (e.g., phosphorus) and usable «fixed» nitrogen from the atmosphere for photosynthetic products.

The researchers, however, did not stop looking until they considered using cyanobacteria — a photosynthetic blue - green algae known for its ability to survive in water.

Sea ice is critical for polar marine ecosystems in at least two important ways: (1) it provides a habitat for photosynthetic algae and nursery ground for invertebrates and fish during times when the water column does not support phytoplankton growth; and (2) as the ice melts, releasing organisms into the surface water [3], a shallow mixed layer forms which fosters large ice - edge blooms important to the overall productivity of polar seas.

Algae - Photosynthetic, often microscopic and planktonic, organisms occurring in marine and freshwater ecosystems.

However, the Earth harbors a greater diversity of photosynthetic organisms than vascular plants, and includes algae, cyanobacteria, and anoxygenic photosynthetic bacteria, all of which occur in a wide array of colors, due to adaptation and acclimation to different light and chemical environments.
