Question

Vacuolization and development of end wall perforation in sieve tube elements are examples of _______

• A. development
• B. differentiation
• C. dedifferentiation
• D. redifferentiation

Answer 1

Answer:

B. differentiation

• Differentiation is responsible for the vacuolization and development of end wall perforation in sieve tube elements.

• Differentiation is the division and growth of cells in order to attain maturity.

• Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions.

• Redifferentiation is the maturation of dedifferentiated cells thereby specializing for a particular function.

• Development includes all the changes undergone by a living plant from seed emergence to death.
