Differentiation between root apex and shoot apex |
|
Answer» hy... friend.....
Shoot Apex ······························ ⇒ Primordia of the branches develop in the axils of leaves in the REGION of apex. ⇒ Branches arise exogenously. ⇒ Plastochrons or periodic cyclic changes occur on the flanks of the shoot apex. ⇒ Shoot apex changes its activity during reproductive phase. ⇒ The organization of shoot apex can be explained on the basis of tunica CORPUS theory. ⇒ Demarcation of the different regions of the meristem and its DERIVATIVES is not elaborate. Root Apex ································· ⇒ Primordia of branches develop far behind the root apex. ⇒ Branches develop endogenously. ⇒ They are not distinguishable in the root apex. ⇒ No change occurs during reproductive phase. ⇒ The organisation of root apex can be explained on the basis of HISTOGEN theory. ⇒ There is a high degree of differentiation in the meristem and its derivatives. thankyou brainy user |
