Solution
The correct option is B Programmed cell death
A. Cell necrosis - is a form of cell
injury which results in the premature death of cells in living tissue
by autolysis.
B. Pinocytic activity - is
a mode of endocytosis in which small particles suspended in extracellular fluid
are brought into the cell through an invagination of the cell membrane,
resulting in a suspension of the particles within a small vesicle
C. Programmed cell death is the death of
a cell in any form, mediated by an intracellular program. PCD is
carried out in a biological process, which usually confers advantage during an
organism's life-cycle.
D. Cell senescence- is a phenomenon
by which normal cells cease to divide
So, the correct option is ‘Programmed
cell death’.
