Meristematic cells called the _____ add width to the plant body.shoot tip
root tip
vascular cambium
phloem

Answers


vascular cambium


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.
