Which of the following cells undergo multiple divisions for apical growth or the growth at the tips of stems?
a. cells of collenchyma
b. meristematic cells
c. pith cells

Meristematic Cells

Contains meristimatic cells, apical meristems are found in the tips of the roots and in the buds of the shoots. They supply cells for the plants to grow in length.

Apical Meristems are found in herbaceous plants, woody plants, grasses, and flowering plants.

In flowering plants, shoot apical meristem develops into an inflorescence meristem which produces the floral meristem. The floral meristem is responsible for the production of the sepals, petals, stamens, and carpels of the flower.
