AP BIOLOGY

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: -Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Apical meristems are found at the apex, or tip, of roots and buds, allowing roots and stems to grow in length and leaves and flowers to differentiate.

Detailed explanation-3: -The apical meristem, also known as the “growing tip, ” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants.

Detailed explanation-4: -Meristematic tissue is analagous to stem cells in animals: meristematic cells are undifferentiated continue to divide and contribute to the growth of the plant. In contrast, permanent tissue consists of plant cells that are no longer actively dividing.

Detailed explanation-5: -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.
