The cells in your body are specialized to perform particular tasks. What is the specialization of your muscle cells?
They are built to protect the body as it moves
They are shaped to take in nutrients needed for the proper functioning of particular body parts
They are shaped to move particular body parts
Built in a sturdy manner to allow for easy movement
All cells in an organism grow from a single cell that has repeatedly divided. However, all the cells in an organism are not the same. Why is this?
Cells are like identical twins. They remain exactly the same with each division.
As the cells divide, they become smaller and smaller.
One new characteristic is added with each cell division.
Different cells are required to perform different jobs.

Their ability to reproduce
They're ability to respond to their environment
The size to which the organisms can grow
Functions carried out by the cell(s)

Epidermal tissue
xylem tissue
phloem tissue
Epithelial tissue

Organs are structures in the body that perform a particular function
An organ is a group of several tissues working together
The ear, the eye, and mouth are all examples of organs
An organ is a group of similar cells working together
