• B. Maturation region
• C. Proximal to cell elongation zone.
• D. Distal to cell elongation zone

Answer 1

Answer: (A)

Region of cell elongation

The protoplasm of the cell is surrounded by a primary cell wall which is laid down as the cell begins to grow. It is thin and composed of cellulose, hemicellulose and pectic substances. Once growth has ceased a secondary cell wall may form inside the primary cell wall.

So, the correct option is 'Region of cell elongation'.
