Question

During ripening, a fruit becomes soft and pulpy due to dissolution of

• A. Secondary walls
• B. Primary walls
• C. Middle lamellae
• D. None of the above

Answer 1

Answer: (C)

Middle lamellae

The cells in plants are composed of a primary and secondary cell wall that are essential for the plant to survive the harsh conditions that it has to live in. Middle lamella is a layer of pectin that is present outside primary cell wall and acts as cementing between cells. It provides extra rigidness and strength to the plant tissue. During ripening of the fruit, the middle lamella gets dissolved to make the fruit soft and pulpy.

So, the correct answer is 'Middle lamellae'.
