11. For an organism to be classified as a plant, name which organelles would have to be present. _________________________ Nucleus
12. Explain why the organism below can’t be either a plant or an animal. Use the organelles present to help you with your answer.
_________________________ This organism has a _________________________ chloroplast, so it could be ____________________ a plant, except it also has _________________________ a flagellum for movement. _________________________ Therefore, it’s neither plant _________________________ nor animal. Definitely a Eukaryote: Protist
