CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The cells of such meristems have the capacity to divide and self-perpetuate. The product, however, soon loses the capacity to divide and such cells make up the plant body. This form of growth wherein new cells are always being added to the plant body by the activity of the meristem is called the open form of growth.

Detailed explanation-2: -The constant dividing phase of cells at the shoot and root apex both indicate the meristematic phase of growth. The cells present in the shoot and root apex are meristematic cells. Meristematic cells are the only cells of plants that have a tendency to divide.

Detailed explanation-3: -Meristem is responsible for the growth of plant. It is responsible for lengthening of roots, shoots. While intercalary meristem is responsible for the increase in the girth of the plant.

Detailed explanation-4: -Secondary growth is the growth which results due to the activities of the primary and secondary lateral meristem. This kind of growth results in the increase of girth of the plant.

Detailed explanation-5: -Conclusion. Plants grow through a combination of cell division and cell growth. Cell division increases the number of cells through cell mitosis, and cell growth increases the cell size. The growth phases are divided into 3 phases: The meristematic phase, elongation phase, and maturation phase.
