The ability to carry out photosynthesis is characteristic of both swimming and attached protists called algae.

Explanation:

The wide spectrum of photosynthetic eukaryotic species not generally closely connected to each other and thus polyphyletic is overall named as algae. Included species range from single-cell microalgae, like chlorella and diatoms, to multicellular types, like the massive kelp, a wide brown algae that can develop up to 50 m long.

The number of are aquatic and self preparing food species which lack number of the distinctive forms of cells and tissues which are located in land plants such as phloem, stomata and xylem.
