👉 Euglenophytes are a group of plants that primarily contain cells from two types of algae, cyanobacteria and sulfur bacteria. These organisms have a unique structure where they use chloroplasts to photosynthesize, allowing them to produce their own food through the process of photosynthesis without needing sunlight directly. Euphorbias typically grow in shallow water or near the surface of bodies of water, including lakes, rivers, and oceans.
