Photomicrographs of meristematic Allium cepa cells treated with tartrazine [Cells were colored by acetic orcein and observed at 400x by optical microscopy. a Cells at different cell cycle phases (Int – Interphase; Prof – Prophase; Met – Metaphase; Tel – Telophase) in negative control; b NB (Bud nuclear) in ​​cells treated with the positive control; c C-met (colchicine metaphase) in cells treated with 100 µg/mL of TRZ; d CB (chromosome bridge) in cells treated with 200 µg/mL of TRZ; e: CL (chromosomal loss) in cells treated with 400 µg/mL of TRZ; f CD (chromosome delay) in cells treated with 400 µg/mL of TRZ
