Cynobacteria and some other photosynthesis bacteria don't have chloroplasts. How do they conduct photosynthesis ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Organisms**: Cyanobacteria and some other photosynthetic bacteria are classified as prokaryotes. This means they lack a defined nucleus and membrane-bound organelles, which are typically found in eukaryotic cells.

2. **Cell Structure**: Prokaryotic cells, such as those of cyanobacteria, do not have chloroplasts like higher plants. Instead, they possess a simpler cellular structure.

3. **Photosynthetic Pigments**: Despite the absence of chloroplasts, cyanobacteria and photosynthetic bacteria contain photosynthetic pigments. These pigments are essential for capturing light energy.
