How many chromosomes in onion root cell

WebIn onion root tip, each somatic cell contains 8 chromosomes. A cell undergoing cell division has duplicated its chromosomes thus a cell at metaphase stage of cell division has 16 chromosomes. As each chromosome has two kinetochores thus during metaphase 32 kinetochores can be seen. So, the correct answer is '32'.
