Subsequently, some aerobic (or oxygen - breathing) protists merged with photosynthetic bacteria, which became chloroplasts and other plastids, to create free - swimming green algae and the precursors of today's plant cells.

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.

Given at least nine meters (roughly 30 feet) of water on the planet, photosynthetic microbes (including mats of algae, cyanobacteria, and other photosynthetic bacteria) and plant - like protoctists (such as floating seaweed or kelp forests attached to the seafloor) could be protected from «planet - scalding» ultraviolet flares produced by young red dwarf stars, according to Victoria Meadows of Caltech, principal investigator at the NASA Astrobiology Institute's Virtual Planetary Laboratory.

Plastids, including chloroplasts, are the corresponding photosynthetic organelles of plant and algae cells.

«Coral breaching, in which symbiotic photosynthetic algae of corals are killed by high temperatures and coral reefs are severely damaged, is regarded as a serious environmental issue, but plausibly, similar phenomena may be ubiquitously found in the ecosystem,» said Dr. Fukatsu.

Corals are communities of animals that have tiny photosynthetic algae living inside them in a mutually beneficial relationship.

Even more crustal minerals were formed by plate tectonics with the help of lubricating ocean water, atmospheric oxygen from the successful development of photosynthetic microbes, and land - based lichens (of algae and fungi) and mosses which were followed by deep - rooted plants that hastened the erosion and weathering of surface rocks with the help of biochemical action and the creation of soils as well as new clay minerals.

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.

Known as zooxanthellae, these algae live within the coral's exposed polyp tissues and are a crucially important photosynthetic source of carbon for the host.

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.
