Find out incorrect sentence :-a)Parenchymatous tissues have intercellu...
Incorrect sentence: c) Apical and intercalary meristems are permanent tissues.
Explanation:
Meristematic tissues are the growth tissues in plants that are responsible for cell division and differentiation. They are located in specific regions of the plant and give rise to new cells, which then mature into different types of tissues.
Apical meristems are found at the tips of stems and roots, while intercalary meristems are present in the internodes of grasses and some other plants. Both types of meristems are responsible for primary growth in plants, leading to an increase in length.
Permanent tissues, on the other hand, are derived from meristematic tissues and have lost the ability to divide further. They are categorized into three main types: simple permanent tissues, complex permanent tissues, and special permanent tissues.
Simple permanent tissues include parenchyma, collenchyma, and sclerenchyma. Complex permanent tissues include xylem and phloem. Special permanent tissues include epidermis, cork, and secretory tissues.
Since apical and intercalary meristems are the sites of active cell division and are responsible for the growth in length of plants, they cannot be classified as permanent tissues.
Conclusion:
Option c) "Apical and intercalary meristems are permanent tissues" is the incorrect sentence. Apical and intercalary meristems are actually examples of meristematic tissues, which are responsible for the growth and development of plants.
