Question

The air spaces in the leaf is created by

• A. Chlorenchyma
• B. Aerenchyma
• C. Palisade parenchyma
• D. All of the above

Answer 1

The correct option is B Aerenchyma

• The spongy tissue that forms air spaces between the cells of leaves, stems, and roots of some plants is called aerenchyma cells.
• It helps in the gaseous exchange and also provides buoyancy to the aquatic plants.
• Chlorenchyma is the parenchymatous tissue that contains chloroplasts and is photosynthetic.
  
• Palisade parenchyma is the upper layer of ground tissue in a leaf. It consists of elongated cells and can perform photosynthesis as it contains chlorophyll. It is an example of chlorenchyma.

So, the correct option is 'Aerenchyma'.
