BOTANY

Detailed explanation-1: -What is cell specialization or differentiation? The process where unspecialized cells become different in structure and function. What is one goal of cellular differentiation/specialization? To create specialized cells to help organism maintain homeostasis.

Detailed explanation-2: -Cell differentiation describes the process of specialization leading to the formation of brain, heart, and all other tissues from the single-cell zygote and the primitive, three-layered embryo.

Detailed explanation-3: -Once a cell becomes differentiated it only expresses the genes that produce the proteins characteristic for that type of cell. Differentiated cells are important in a multicellular organism because they are able to perform a specialised function in the body.
