Detailed explanation-1: -Meristematic tissues are responsible for plant growth. They are present at the tips of roots, stem and branches. The cells present in these tissues constantly divide to produce new cells. This leads to an increase in the height and girth of plants.

Detailed explanation-2: -Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.

Detailed explanation-3: -Meristematic tissue is responsible for the growth processes in plants. The cells of these tissues can divide. It is found mostly at the tip of roots, stems, branches, leaves, buds where there is active growth.

Detailed explanation-4: -Meristematic tissue is growth tissue and the location of most cell division. It is known as undifferentiated tissue because cells in the meristematic tissue will eventually become vascular, ground, or dermal tissue. Plants generally grow where meristematic tissue is present.

Detailed explanation-5: -The function of meristematic tissue is to make plants grow. The cells of meristematic tissue are small and cubical. They also have thin cell walls. They are tightly packed with no intercellular spaces.
