Cell Structure and Functions Every organ in our body performs a variety of different functions such asdigestion,assimilation, and absorption. Similarly, in the plants too, there are differentorgansof the plant which performs specialized or specific functions. For instance, the roots of the plants he...
In an animal cell, the cell membrane functions by providing shape and protects the inner contents of the cell. Based on the structure of the plasma membrane, it is regarded as the fluid mosaic model. According to the fluid mosaic model, the plasma membranes are subcellular structures, made ...
fungi, bacteria, algae, and some archaea. Animal cells however, do not have a cell wall. The cell wall has many important functions in a cell including protection, structure, and support.
The structure of biological molecules Cells are largely composed ofcompoundsthat contain carbon. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organicchemistryand plays a large role in understanding the basic functions of cells. Because...
Cell membrane, thin membrane that surrounds every living cell. The cell membrane functions as a barrier, keeping cell constituents in and unwanted substances out, and as a gate, allowing transport into the cell of essential nutrients and movement from th
The structure of bacteria andarchaeais presented here with some extra focus on the latter. The rationale has been to discuss thecell structure, while going from the outside of the cell to the inside, that is, from cellular appendages to thenucleoid. Special emphasis has been placed on novel...

Main Functions of Bone Tissue The main functions of bone tissue include: Structural support; Protection of internal organs and soft tissues from damage; Locomotion; Mineral storage; Production of blood cells; Endocrine regulation. The basic mechanical...
and connected to the membrane by interactions with other proteins.Integral membrane proteinsare inserted into the membrane and most pass through the membrane. Portions of these transmembrane proteins are exposed on both sides of the membrane. Cell membrane proteins have a number of different functions...
