Correct option is D
The correct answer is: (d) the dividing tissue, also known as meristematic tissue, is located only at these regions
Explanation:
Meristematic tissue is the only plant tissue that has actively dividing cells.
These tissues are found in specific regions such as the tips of roots and shoots, which are responsible for plant growth.
The cells in meristematic tissue are undifferentiated, thin-walled, and have a dense cytoplasm and large nuclei, allowing them to divide repeatedly.
As a result, growth in plants is localized to these regions only.
Information Booster:
Apical meristem – found at the root and shoot tips, responsible for primary growth.
Lateral meristem – found in the vascular cambium and cork cambium; enables secondary growth (thickness).
Intercalary meristem – found at internodes; helps in elongation (mainly in grasses).
Meristematic tissues are not permanent; they eventually differentiate into permanent tissues.
Permanent tissues lose their ability to divide and perform specific functions like transport and support.
Growth in animals is uniform, but in plants, it's restricted to meristematic regions.
Additional Information:
Complex permanent tissue: Includes xylem and phloem; responsible for transport, not division.
Connective tissue: This is a term used in animal tissues, not applicable to plants.
Simple permanent tissue: Includes parenchyma, collenchyma, and sclerenchyma; these do not divide.
