Which are growth tissues of plants? How do they categorize and where can they be found?
Growth tissues of the plants are the meristems. The Meristems are the tissues that produce the plant growth giving birth to all other tissues; and they are formed of undifferentiated cells having intense cell division rate. The Meristems categorize as primary meristems and as secondary meristems.
The Primary meristems are found in the apex of the stem, in the lateral buds of the stem, in the basis and tips of the shoots and within the root cap. The Primary meristems are responsible for the primary growth (lengthening) of the plant.
The Secondary meristems are those that make the plant grow in thickness (secondary growth) and they are formed by tissues that thicken the stem: cambium and phellogen (cork cambium).
