Why are animal cells specialized?

Answer 1

Both animals and plants normally begin life as a single cell, the zygote, because that is how sexual reproduction takes place. (Asexual reproduction can happen in different ways.) Since the organism starts with one cell, the various specialized types of cells must necessarily form in the course of embryonic development (except in the case of unicellular organisms which, having only one cell, also have only one kind of cell). The purpose of specialized cells is also clear. By specializing, it is possible for a cell to do a specific function more efficiently than an unspecialized cell could. An organism made up of specialized cells is a much more effective organism, with greater capabilities.

Answer 2

they need specialized cells because certain cells like a protein cell cannot do what the specialized cells can eg. lysosomes are a special cell that is basically a janitor for the cell it cleans up cell debris that is left behind

Answer 3

Depending upon the type of plant, plant cells can become specialized for different functions. Just as higher animals have organs, plants feature organs of three major types---roots, stems and leaves. Within these are various tissue types, including what are termed xylem and phloem, for example. In vascular plants, some cells develop into water-conducting cells. Collectively they form a tissue called the xylem. Other cells differentiate into cells that conduct food that the plant manufactures in the form of glucose. These cells are called phloem cells, and the tissue they form is called phloem.

Answer 4

Animal cells are specialized because they are expected to perform certain functions. These functions are not performed in plants for example.
