what is cloroplast
A chloroplast is one of three types of plastids, characterized by its high concentration of chlorophyll (the other two types, the leucoplast and the chromoplast, contain little chlorophyll and do not carry out photosynthesis).laucophyte algal chloroplasts have a peptidoglycan layer between the chloroplast membranes. It corresponds to the peptidoglycan cell wall of their cyanobacterial ancestors, which is located between their two cell membranes. These chloroplasts are called muroplasts (from Latin mura , meaning wall).
