8. Hornworts • No true roots • No true leaves • Depend on direct contact with water • Live in moist places

9. Liverworts • Similar characteristics as the other to but • Can be found on rocksand trees • Thrive in moderate or deep shade

10. Ferns • Have a vascular system with roots to help anchor the plant securely to the soil • Main root with smaller roots to obtain water and nutrients

11. How Plants Reproduce • How do plants reproduce to ensure the species of the plant continues? • Take 2 minutes and discuss with your group?

12. All Living Things Reproduce • Plants reproduce • 3 ways • With Spores • Seeds from cones • Seeds from flowers

13. With Spores • Ferns, moss and hornworts reproduce with spores • They look like soft fluff are scattered by the wind fall to the ground and sprout

14. Cones • Conifers produce cones • Seeds are inside these cones and when the cone opens the seeds are scattered by the wind and animals

15. Flowering Plants • Flowering plants produce seeds in a flower or a fruit • These plants include trees, shrubs, vines and flowers. Fruits and vegetables as well
