Detailed explanation-1: -The development of tracheary elements (TEs), the building blocks of the water-conducting tubes in the xylem, from parenchyma cells is an impressive example of plant cell differentiation. Cells of Zinnia elegans that are derived from mesophyll protoplasts can be induced to undergo differentiation to TEs in vitro [57].
Detailed explanation-2: -The cells of multicellular animals and plants must also differentiate, so that its cells develop features that enable them to fulfil specific roles. Cells that have differentiated have become specialised.
Detailed explanation-3: -Cells of which of the following plant organs do not undergo differentiation? Explanation: Cork cell is formed by the process of redifferentiation.
Detailed explanation-4: -Adipose stromal cells. Amniotic fluid-derived cell line. Endothelial. Epithelial. Keratinocyte. Mesothelial. Smooth muscle.
