Question

Which of the following is not a functional attribute of collenchymatous tissue?

• A. Protecting plant parts from stress and strain
• B. Provides flexibility, elasticity and mechanical support
• C. Stores air for maintaining buoyancy in hydrophytes
• D. Stores chlorophyll in young dicot stem and performs photosynthesis

Answer 1

The correct option is C Stores air for maintaining buoyancy in hydrophytes

Aerenchyma, a type of parenchyma tissue stores air for maintaining buoyancy in hydrophytes.

Collenchyma consists of cells which are much thickened at the corners due to a deposition of cellulose, hemicellulose and pectin. Collenchymatous cells may be oval, spherical or polygonal and often contain chloroplasts. These cells assimilate food when they contain chloroplasts. Intercellular spaces are absent. They provide flexibility, elasticity and mechanical support to the growing parts of the plant such as young stem and petiole of a leaf.
