What are Peroxisomes?
Small, everywhere and crucial for cell vitality
Peroxisomes are small organelles (or compartments, membrane-enclosed “rooms”) that occur in almost all cells – from a simple baker`s yeast cell to crop plants and humans. Peroxisomes are essential for cell vitality. For instance, people born with inherited peroxisome defects generally die rather early. Also, oily seeds of crop plants with damaged peroxisomes can no longer germinate and are inefficient in photosynthesis.
