• A. Parenchymatous tissues have intercellular
  spaces
• B. collenchymatous tissues are irregularly
  thickened at corners
• C. Apical and intercalary meristems are
  permanent tissues
• D. Meristematic tissues, in their early stage, lack
  vacuoles

Answer 1

Answer: (A), (C)

Apical and intercalary meristems are
permanent tissues

The correct option is A and C

Explanation of the correct option:

Option A

Parenchymatous tissues have intercellular spaces is the incorrect sentence because they do not have intercellular spaces, therefore, they act as a packing tissue in plants.

Option C

1. Meristematic tissues are not permanent tissue because permanent tissue does not divide after differentiation so this sentence is incorrect.
2. Examples of very common permanent tissues are collenchyma, parenchyma, xylem, phloem, etc.
3. Apical and intercalary meristems are also called primary meristems which are responsible for the vertical growth of plants.

Explanation of the incorrect options:

Option B

Collenchymatous tissues are irregularly thickened in corners and they have intracellular spaces.

Option D

Meristematic tissue does not have vacuole in its early stage hence, this is an incorrect option.

Final Answer: “Parenchymatous tissues have intercellular spaces” and “Apical and intercalary meristems are permanent tissues” are the incorrect statements.
