Members оf the plаnt fаmily Cаctaceae (cacti) are native tо the Americas and thrive in dry envirоnments. They have a number of specialized adaptations, including reduced leaves, succulent (fleshy) stems for water storage, and spines for defense against herbivores. Some members of the family Euphorbiaceae are native to Africa and resemble cacti, having similarly reduced leaves, succulent stems, and thorns. However, their common ancestor likely did not have these traits. Based on this information, what can you say about the morphological traits of Cactaceae and Euphorbiaceae indicated above?
