1.	The cells of tracheary elements lose their protoplasm and become dead at maturity due to the deposition of lignocellulosic secondary cell well formation. This is an example of _________(a) redifferentiation(b) development(c) dedifferentiation(d) differentiationI had been asked this question in an international level competition.This question is from Plant Growth and Development topic in division Plant Growth and Development of Biology – Class 11
Answer» RIGHT choice is (d) differentiation Best explanation: The formation of secondary CELL wall around TRACHEIDS and vessels is an example of differentiation. Development is the overall changes occurring in the life CYCLE of an organism. Dedifferentiation is regaining the LOST capacity of cells or tissues of plants to divide under special conditions. Redifferentiation is the further maturation of dedifferentiated cells thereby specializing for a particular function.
