1. Plant cells also have an additional organelle called chloroplast for photosynthesis. 2. Most algae contain chloroplasts that are similar in structure to cyanobacteria. 3. Glaucophyte algal chloroplasts have a peptidoglycan layer between the chloroplast membranes. 4. Glaucophyte algal chloroplasts have a peptidoglycan layer between the chloroplast membranes. 5. Starch granules vary in composition and location across different chloroplast lineages. 6. The chloroplasts of some hornworts and algae contain structures called pyrenoids. 7. Light has been shown to be a requirement for chloroplast division. 8. Chloroplasts contain the green pigment chlorophyll which is needed for photosynthesis.9. Grana contribute to chloroplasts 'large surface area to volume ratio. 10. These shuttle systems also have the same transport function in chloroplasts .
