What will happen if (a) Apical meristem is damaged or cut? (b) Cork is not formed in older stems and roots. (c) Lymph is not returned to blood?

(a) If apical meristem is damaged or cut, then growth in length of the plant will stop.
(b) If cork is not formed in older stems or roots, the outer. tissues will rupture due to increase in girth (secondary growth) which expose the interior to dessication and infection.
(c) If lymph is not returned to blood, the blood volume will decrease and while passage of materials from tissues to blood and vice versa would be disturbed
