Question

The collenchyma without intercellular space is

• A. Angular
• B. Lacunar
• C. Lamellar
• D. Both A and C

Answer 1

Answer: (D)

Both A and C

Angular Collenchyma is characterized by the deposition of hemicellulose and pectin only in the angles between the cells. The cells are compactly arranged and intercellular spaces are absent. It is found in the stem, usually below the epidermis, forming a region called hypodermis.
Lamellar Collenchyma is characterized by the deposition of hemicellulose and pectin occurs only at the crosswalls separating the adjacent cells. The cells are compactly arranged without any intercellular spaces. This type is found usually in the petiole of leaves.
Lacunar Collenchyma is in which the cells are either spherical or oval in shape and enclose small intercellular spaces. The deposition of hemicellulose and pectin occurs only along the border of intercellular spaces. This type of collenchyma is usually found in the fruit wall.
Therefore, the correct answer is option D.
