Plastid — Plastids are major organelles found in plants and algae. Plastids often contain pigments used in photosynthesis, and the types of pigments present can change or determine the cell s color. Plastids are also the site of manufacture and storage of… … Wikipedia
Amyloplast — Amyloplasts also convert this starch into sugar, for when the plant needs energy. In the day, in plants, there is more sugar than starch present. At night, there is more starch than sugar present.Large numbers of amyloplasts can be found in… … Wikipedia
Chromoplast — Chromoplasts are plastids responsible for pigment synthesis and storage. They, like all other plastids (including chloroplasts and leucoplasts), are organelles found in specific photosynthetic eukaryotic species. Chromoplasts in the traditional… … Wikipedia
