Answer

No, not all organisms that photosynthesize have chloroplasts; some, like cyanobacteria, use thylakoid membranes. Explanation 1. Identify Organisms That Photosynthesize Plants, algae, and some single-celled organisms photosynthesize using chloroplasts. 2. Consider Exceptions Some bacteria, like cyanobacteria, photosynthesize without chloroplasts. They use thylakoid membranes instead. 3. Conclude Based on Evidence Not all photosynthetic organisms have chloroplasts; some use alternative structures.
