Animal and Plant cells

[Adam Marchese]

I have severly questions about animal and plant cells?  My first question 
is that in animal cells, what is the function of the Skeletal Muscles, 
Cardiac Muscles, Smooth Muscles and Nervous.  Also, is there a place on 
the internet all about biology?  My finally question is that,in the plant 
cell, what functions do the meristemic, epidermal, cork, parenchyma, 
collenchyma and Phloem have?
