Does anyone have any idea how to answer this question:
  1. Using this principal of surface area to volumeratio, explain why humans need specialised cells and tissues in order tosurvive. You should consider the advantages of differentiation of cell typesover the basic animal cell structure.
Really stuck would appreciate some idea
Thanks

my ideas are;

humans have a small surface area to volume ratio - so they cannot absorb needed products by diffusion (as diffusion needs as large surface area to volume ratio for steady diffusion)
This means they need other methods of absorbing products which are vital for their survival, such as having different specialised transport systems
An example of a specialised transport system is the digestive system
Within this system we obviously have specialised organs such as the small intestines
And these specialised organs are made up of specialised tissues.
Different tissues have different functions, such as muscular tissue are made up of muscle cells which contains lots of mitrochondria and therefore provide lots of energy.
Advantages;
Having specialised tissues and therefore specialised cells means that cells can each take on a seperate task and perform it simultaneously with each other, some can perform basic functions while others can be used in growth etc.
They can also help perform more complex tasks

Ignore any spelling mistakes haven't been in an english lesson for a year and now my brain refuses to let me spell correctly lol

Thank you so much for your reply, that makes total sense now. I have been going out of m mind writing this assignment as I couldn't understand the whole idea.

Thanks again
