|
Parenchymatous tissues have intercellular spaces
|
|
|
Collenchymatous tissues are irregularly thickened at corners
|
|
|
Apical and intercalary meristems are permanent tissues
|
|
|
Meristematic tissues, in its early stage, lack vacuoles
|
Detailed explanation-1: -Final Answer: “Parenchymatous tissues have intercellular spaces” and “Apical and intercalary meristems are permanent tissues” are the incorrect statements.
Detailed explanation-2: -The apical meristem is located at the tips of roots and shoots. The intercalary meristem is present at internodes. They are primary meristems and are not permanent tissues.
Detailed explanation-3: -Answer: Permanent tissues are made of meristematic cells, that has definite form and shape and have lost the power to divide and differentiate and are of three types-simple, complex and special. The simple tissues are parenchyma, sclerenchyma and collenchyma. Chlorenchyma is a parenchyma, having chloroplast.
Detailed explanation-4: -Although they differentiate to produce many kinds of permanent tissues, apical and intercalary meristems are not permanent tissues.
Detailed explanation-5: -Meristematic tissues in plants consist of a mass of undifferentiated cells whose main function is to participate in plant growth. Permanent tissues, on the other hand, are differentiated tissues, carrying out dedicated functions.
