Differentiation requires inactivation of particular genes to produce populations with limited capabilities that form tissues.
Explanation;
-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.
-Gene expression plays a critical role in the morphological changes that take place in a developing embryo and fetus and in the differentiation of stem cells to form specialized cells.
Primary growth or lengthening of plants results from mitotic division in cells of the apical meristem tissue. The apical meristem can be found in the top of plants. When the plant divides, it helps to lengthen it. The correct choice is C.
