Cyanobacteria produced oxygen.
Scientists believe the first photosynthetic organisms may have been cyanobacteria. This is believed because the biochemical pathways in the unicellular cyanobacteria.
To reduce the amount of carbon dioxide in the atmosphere, scientists are planting more green plants e.g. forests. Green plants require carbon dioxide for photosynthesis.
They believed plants evolved from prehistoric times.
Although cyanobacteria do not have chloroplasts, they do have thylakoid membrane, where photosynthesis occur.
The dinosaur is thought to be the ancestor of all things today.
Algae, plants, and cyanobacteria.
Cyanobacteria have the same green pigment that plants have, chlorophyll, and use it to make energy.
Cyanobacteria > Red Algae > Green Algae > Land Plants
There were no animals or plants at the start of the earth. Cyanobacteria maybe
one is the gymnosperm phyla Cycad
Scientists believe that plants evolved directly from a freshwater green algae called charophyte. There are two different types of charophytes, coleochaetales and charales, which strongly resemble earliest land plants.
