Answer:
cells specialize to form specific tissue and organs because all cells have the same DNA. stem cells can develop into every type of cell inside the body.The cell is the basic unit of structure and function in all living organisms.
Transport proteins require energy because they are pumping materials. Without energy, they won't function and we will have huge problems in our body.
I hope this helps! :D
Biology > Cell biology > Passive transport
There are different types of transport in the cell that can be classified into two groups: passive transport (which does not require energy) and active transport (which requires energy because it goes against the concentration gradient).
Diffusion is a type of passive transport and it does not require energy, it can be divided into simple diffusion (molecules pass through the membrane without the help of any channel) and facilitated diffusion (molecules pass through the membrane with the help of a protein channel).
Facilitated diffusion will transport certain molecules and simple diffusion others. Larger, polar and charged molecules will need help to cross the membrane, so they will do so by facilitated diffusion. Therefore, the answer is D.
