Necessary cookies are absolutely essential for the website to function properly. It was initially believed that protists only reproduce asexually, however recent studies have revealed that they also resort to sexual reproduction, especially under stressful conditions. When there is extreme environmental stress, which makes survival difficult, some protist organisms exchange genetic material with the intention of producing an off-spring which will have the ability to survive in the prevailing extreme environment. Some protists undergo an alternation of generations, including slime molds, foraminifera, and many marine algae.
