What organelle present in algae and plant cells lacking cynobacterial cells?

Algae and plant cells contain chloroplasts, which are organelles responsible for photosynthesis, converting light energy into chemical energy. In contrast, cyanobacterial cells do not have chloroplasts; instead, they carry out photosynthesis using thylakoid membranes located within the cytoplasm. This difference highlights the complexity and specialization of eukaryotic cells compared to prokaryotic cells like cyanobacteria.
