Question

Identify the given figure and select the correct option for A, B and C.

• A. A - Leaf primordium
  B - Shoot apical meristem
  C - Apical bud
• B. A - Leaf primordium
  B - Shoot apical meristem
  C - Axillary bud
• C. A - Root hair
  B - Root apical meristem
  C - Axillary bud
• D. A - Root hair
  B - Root apical meristem
  C - Apical bud

Answer 1

The correct option is B A - Leaf primordium

B - Shoot apical meristem
C - Axillary bud

The shoot apical meristem (SAM), at the tip of the plant stem, has two roles; it is the source of the new cells that are needed for stem growth, and it is the site for small cellular outgrowths, called leaf primordia (LP), that develop into the leaves. Axillary bud is a lateral bud, which remains dormant under the influence of auxin produced by the apical meristem.
