Primary vs Secondary Meristems

Read the following statement regarding meristematic cells and select the CORRECT ones (i) shoot apical meristem occupies the distant most region of the stem axis. (ii) The meristem which occurs between mature tissues is known as intercalary meristem. (iii) Both apical meristems and intercalary meristems are secondary meristems.

Differentiate between Primary meristem and secondary meristem

Interfascicular cambium is (a) Intercalary meristem (b) Secondary meristem (c) Apical meristem (d) Noncalary meristem

All of the following are secondary meristems except

The order of reactivity of alcohols towards sodium metal is (A) Primary > Secondary > Tertiary (B) Primary (C) Tertiary > Primary > Secondary (D) Secondary > Tertiary > Primary

In elimination reactions, the reactivity of alkyl halides is in decreasing order: Tertiary > Secondary > Primary Primary > Secondary > Tertiary Secondary >Primary > Tertiary None of These

Differentiate between the following Primary and Secondary Phloem

The process of formation of secondary meristem from primary permanent tissue is called:-

Assertion :- Vascular cambium of dicot stem shows dual origin. Reason :- Partially it is made up of primary meristem and partially from secondary meristem.

Give two exmaples of secondary meristems.
