Only some are.
No, there are some photosynthetic protists and some photosynthetic bacteria.
Unicellular,filamentous and photosynthetic organisms are ALGAE
Chlorophyll is the principal pigment in photosynthetic organisms that absorbs light energy for photosynthesis.
Why do plants and other photosynthetic organisms need CO2 from the atmosphere?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Bacteria
Amoeba are not photosynthetic. They do not have chloroplasts
Photosynthetic organisms require sunlight, water, and carbon dioxide to carry out photosynthesis effectively.
Photosynthetic organisms use sunlight to produce energy through photosynthesis, while chemosynthetic organisms use inorganic compounds to produce energy. Photosynthetic organisms include plants, algae, and some bacteria, while chemosynthetic organisms can be found in environments such as deep-sea hydrothermal vents.
No, paramecia are not photosynthetic. Photosynthetic organisms react when exposed to light. Paramecia cannot detect light.
