Among the organisms listed, Chilomonas, Volvox, and Paranema have cell walls that contain chloroplasts.
Chilomonas is a genus of flagellated protists that exhibit both unicellular and colonial forms. They possess chloroplasts, enabling them to perform photosynthesis, and typically have a cell wall made of cellulose.
Volvox is a well-known colonial organism where individual cells are connected to form a spherical colony. Each cell has chloroplasts for photosynthesis and is surrounded by a gelatinous matrix, providing structural integrity.
Paranema is another flagellated protist that has chloroplasts. It features a simple structure with cell walls that allow for photosynthesis, similar to the other two organisms.
On the other hand, Paramecium and Amoeba do not possess photosynthetic capabilities and lack chloroplasts. Paramecium has a flexible pellicle instead of a rigid cell wall, while Amoeba, which is an amoeboid protist, lacks both a cell wall and chloroplasts.
In summary, the organisms with cell walls and chloroplasts from your list are Chilomonas, Volvox, and Paranema.
