Question 2. Discuss the characteristics of meristematic tissue.
Answer.

The characteristics of meristematic tissue:

The cells are oval, rounded or polygonal in shape. The cells are living with thin cellulose walls and without any intercellular spaces The cells are rich in cytoplasm with very small vacuoles. The cells are diploid and undergoes mitosis. The cells do not contain reserve food materials, endoplasmic reticulum and plastids.
