CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cell s grow, they also become specialized into different cell types through cellular differentiation.

Detailed explanation-2: -Cell size at completion of mitosis is correlated with growth rate during mitosis.

Detailed explanation-3: -Cell proliferation is the process of generating an increased number of cells through cell division. Both cell division and growth are tightly linked to the cell cycle and its regulation.

Detailed explanation-4: -Cell growth-an increase in cytoplasmic mass, chromosome number, and cell surface-is followed by cell division, in which the cytoplasmic mass and chromosomes are distributed to the daughter cells. An increase in cytoplasmic mass does not always occur during cell-division cycles, however.

Detailed explanation-5: -As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
