How are animal cells linked to each other?
Animal cell functions and organelles are linked to each other. In fact, the collective work of the animal cell parts is responsible for overall functioning of the cell. Let’s take an example of ribosome organelle, which does the main function of protein production. Likewise, mitochondria are centers for releasing energy. And, it is because of the lack of cell wall that makes animal cell a more diverse type. Some cell functions with respect to its specific parts are explained below.

What is the function of the selective permeability of the cell membrane?
The selective permeability of the cell membrane allows the cell to regulate itself and maintain homeostasis.
What are the macromolecules that are incorporated in the cell membrane?
Embedded within the cell membrane are all sorts of macromolecules such as glycoproteins, which act as recognition sites or aid in stability, and channel proteins, which allow certain materials in and out of the cell. The cell membrane is semi-permeable, which means that only certain molecules are allowed to pass through the membrane easily. Other molecules must use the channels in the membrane to gain access to the cell. The selective permeability of the cell membrane allows the cell to regulate itself and maintain homeostasis.
