Scientists believe the first photosynthetic organisms may have been cyanobacteria. This is believed because the biochemical pathways in the unicellular cyanobacteria.
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.
Photoautotrophs
protista
The organism that fits this description is protists. They are multicellular, can photosynthesize, and have DNA contained in their nucleus. Bacteria and archaea are single-celled organisms and do not possess a true nucleus.
Photosynthesis occurs in a variety of bacteria, algae and plants. All other organisms, including animals, are not able to photosynthesize.
Organisms that photosythesize get their energy from the sun
The first organisms that were the first forms of life and were able to photosynthesize, were plankton. Most of our oxygen comes from the plankton living in the oceans. They play a big role in our everyday life, sharing that position with plants and all nature life (of plants).
photosynthesize
chlorophyll
carbon dioxide. or, CO2
Fungi has a cell wall of chitin and cannot photosynthesize
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.

Photoautotrophs
protista
Organisms in the plant kingdom include grasses, trees, ferns, mosses, and flowering plants. These organisms are characterized by their ability to photosynthesize and produce their own food.
