Cells have different shape to allow them to work better. For example, the alveoli cells are flat and big in surface, these features helps in gas exchange.

Cells that do a certain task for the body often have a shape that helps them perform that task. For example, skeletal muscle cells are long and thin, which enables them to contract and move the body. Nerve cells have long branches that enable them to connect to and communicate with other nerve cells. A glycoprotein is a special type of protein. Glycoproteins are proteins with a chain of sugars attached. Different glycoproteins have different sugar chains, so they can be used by the cells of your body to help recognize different things. Your list is already in order from least to most complex.

their shapes are specialised for their specific functions. i think that one sentence really just said it all.. if you need examples, yes the alveoli (surface area for gas exchange). also erythrocyte, villus, same. some bacteria have their flagella to swim.. sperms too.. how about neurons, adipocytes.. epithilium are also made up of thin layers for easy diffusion (but in this case is a little swayed to tissues not cells)

it helps a lot! examples...HUMANS:cilliated cells in ur airways (except broncules) have cillia to catch dust.....UNICELLULAR ORGANISMS:falgelli (hair like structre) on falgellum (type of bacteria) gets it moving around,,PLANTS:Root hair cells have the elongated structure to keep large surface area to increase rate of diffusion through osmotic pressure....if all of these cells didnt have these special shapes the organims the are in wudnt have lived

AND jonathon alveoli are not cells they are air sacks made from epitillial cells...now these epithilial cells help because of thier very thin structures..faster diffusion..
