Lab-grown meat begins with cells taken from an animal. Those cells are then fed water and salt and nutrients like amino acids, vitamins and minerals. The cells then multiply in large tanks called cultivators or bioreactors. When harvested, the product is essentially minced meat, which is then formed into patties, sausage or fillets. The meat contains no bones, feathers, beaks or hooves and does not need to be slaughtered.
