Plastids 3 Types Leucoplasts – found in Potatoes - Store Starch Chromoplasts – found in flowers - Give the colour pigments Chloroplasts – found in green leaves - give leaves green pigment - site of photosynthesis

Chloroplasts Two views of the same cells with slight adjustment in focus. (chloroplasts)
