Question

Which one of the following characteristics feature is not applicable to parenchyma?

• A. It forms the major tissue within organs
• B. Cells are generally brick shaped closely packed with intercellular spaces
• C. Their walls are thin and made up of cellulose
• D. Parenchyma perform the functions like photosynthesis, storage, secration and machanical support

Answer 1

Answer: (B)

Cells are generally brick shaped closely packed with intercellular spaces

Parenchyma is a thin walled cell. These are packed compactly without the intercellular spaces. It is considered as a part of a simple permanent tissue. It forms the ground tissue and acts as a filler in various organs. It also forms the soft tissues of fruits. A generalized plant cell type, parenchyma cells are alive at maturity. They function in storage, photosynthesis, and as the bulk of ground and vascular tissues. Palisade parenchyma cells are elongated cells located in many leaves just below the epidermal tissue.

Therefore, the correct answer is option B.
