CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Apical meristems can divide into three types of primary meristems: Protoderm: The outermost layer of the stem that develops into the epidermis. Procambium: A protoderm cell that develops into primary xylem and primary phloem. Ground meristem: This is made up of cells from the parenchyma, collenchyma, and sclerenchyma.

Detailed explanation-2: -The outermost layer of cells across the top of the apical meristem and leaf primordium is a meristem called the protoderm: its cells are still dividing and their progeny cells will develop into epidermis cells.

Detailed explanation-3: -The shoot apical meristem contains cells that undergo continual growth and division to generate the building blocks for the aerial portion of the plant. As cells leave the meristem, they undergo differentiation to form specific cell types.

Detailed explanation-4: -…the plant body: the outermost protoderm differentiates into the epidermis, a tissue that protects the plant; the adjacent ground meristem differentiates into the central ground tissues (the pith and cortex); and the procambium differentiates into the vascular tissues (the xylem, phloem, and vascular cambium).

Detailed explanation-5: -Primary meristems Apical meristems may differentiate into three kinds of primary meristem: Protoderm: lies around the outside of the stem and develops into the epidermis. Procambium: lies just inside of the protoderm and develops into primary xylem and primary phloem.
