Answer 2

Answer:

A tissue whose cells are capable of "cell division" are "Meristematic Tissue".

Found in the plants, meristematic tissues are the living tissues that are present in the growing portions of the specialised plant parts. Meristematic tissues contain living, undifferentiated cells which divide actively  to create structures like the buds of the flowers, tips of roots and shoot, cambium, etc. It is the meristematic tissue that helps a plant to increase in length and girth.
