Open in App
Solution
The correct option is B aerenchyma
Aerenchyma is commonly found in hydrophytes (plants that are found growing wholly or partially submerged in water), such as water lily. It helps in buoyancy or floating. This is due to the presence of large intercellular spaces.
When chloroplasts are found in parenchyma and collenchyma, the tissue is called chlorenchyma and it helps in photosynthesis.
Spongy parenchyma is parenchyma with considerable intercellular spaces. It helps in the exchange of gases and also helps water to evaporate as water vapour through the process of transpiration.
Collenchyma is an example of a simple permanent living mechanical tissue. The cell wall is made of cellulose, hemicellulose and pectin. The presence of pectin enables the tissue to provide mechanical support to the plant.
