11. Plants and various groups of algae also have plastids . 12. Lesson No . 1 here is the shock that they even have a plastid . 13. Some retain plastids , but not chloroplasts, while others have lost plastids entirely. 14. Some retain plastids, but not chloroplasts, while others have lost plastids entirely. 15. The outer plastid -dividing ring is found wrapped around the outer chloroplast membrane. 16. This supports the endosymbiotic theory of the evolution of plastid division in land plants. 17. Transfer-messenger RNA ( tmRNA ) is found in many bacteria and plastids . 18. They are generally found in mature tissues and are derived from preexisting mature plastids . 19. The ancestors of plastids diversified into a variety of plastid types, including chromoplasts. 20. The ancestors of plastids diversified into a variety of plastid types, including chromoplasts.
