NEET BIOLOGY

Detailed explanation-1: -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-2: -The correct answer is cell differentiation. Cell differentiation is the process by which proliferating cells are transformed into more specialized cell types. Cells proliferate and differentiate to change from one cell type to another or are transformed into more specialized cell types.

Detailed explanation-3: -Cell differentiation is the process by which cells become specialized in order to perform different functions. Multicellular organisms begin as just one single cell-a fertilized egg.

Detailed explanation-4: -The process of hematopoiesis involves the differentiation of multipotent cells into blood and immune cells. The multipotent hematopoietic stem cells give rise to many different cell types, including the cells of the immune system and red blood cells.

Detailed explanation-5: -Stem cell differentiation involves the changing of a cell to a more specialized cell type, involving a switch from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane potential, metabolic activity and responsiveness to certain signals.
