• B. Parenchyma- Cells are thick walled and unspecialised, Sclerenchyma- Cells are thick walled and lignified
• C. Parenchyma- Cells are thick walled and lignified, Sclerenchyma- Cells are thin walled and unspecialised
• D. Parenchyma- Cells are thin walled and specialised, Sclerenchyma- Cells are thick walled and lignified

Answer 1

Answer: (A)

Parenchyma:
(1) Cells are thin walled and unspecialised. (2) These are living cells. (3) Cells are usually loosely packed with large intercellular space. (4) Stores nutrients and water in stem and roots. (5) Some cells contain chlorophyll, called as chlorenchyma and perform photosynthesis. Other cells have large air cavities, called as aerenchyma, which provide buoyancy to the hydrophytic plants.
