Here are some examples of photoautotrophs:

* Plants: This is the most well-known group of photoautotrophs. They have chloroplasts, which contain chlorophyll, the pigment that absorbs sunlight for photosynthesis.

* Algae: This diverse group includes single-celled organisms like diatoms and larger multicellular organisms like seaweed.

* Cyanobacteria: These are bacteria that can perform photosynthesis. They were responsible for generating the oxygen in Earth's early atmosphere.

It's important to remember that while all photoautotrophs produce glucose, some might also produce other organic molecules through photosynthesis.
