MICROANATOMY

Detailed explanation-1: -All cells of multicellular organisms derive from a single cell. By the process of cell differentiation, cells gain their specific phenotype and functionality at maturity. Cell differentiation leads to various different types of cells, which perform vital functions.

Detailed explanation-2: -Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

Detailed explanation-3: -Differentiation: Formation of tracheary elements. Dedifferentiation: Formation of vascular cambium and cork cambium (meristems) from fully differentiated meristems. Redifferentiation: Formation of secondary xylem and phloem from dedifferentiated cells of the cambial ring.
