4 SNC2D Plastids

Plastids are organelles in plants that contain, or will or contain or did contain pigments.  Pigments include chlorophyll (green), carotene (orange), xanthophyll (yellow) and lycopene (red).  They are actually antioxidants which one of the reasons why they are healthy to eat.  Today we are making a wet mount of red pepper tissue in order to observe and generate a scientific drawing of cells that contain chromoplasts containing lycopene.
