Why can't they just grow into huge cells and perform the functions they are designed to do?
becuse they must divide so that they can replace the cells that die
Why do cells have different shapes and appearance?
because they all of different type of functions
How did cells become a tissue?
To become a tissue,cells must be physically connected and have the same origin.They may or may not structurally similar.They together perform one or more specific functions.
It is important to clarify what functions and features the system must perform and what functions and features are optional?
true
What functions must a cell be able to carry out?
cells
Who must be first contacted to establish a user authorization to perform CEMAS functions?
Chief
Do all cells perform all functions?
Heck no! The simplest human cells are stem cells from which other types of cells may form. Cells have many diverse functions, blood is one example. There are three general types of cells in blood, red cells (erythrocytes), platelets and white cells (lymphocytes). There are 5 major subclasses of lymphocytes, each with particular functions mostly to do with immunity. Red cells carry oxygen and platelets stick together to plug injured blood vessels. Other major categories include muscle cells (two major types - smooth and striated), nerve cells, and skin cells. Many organs have specific types of cells that are unique to that organ's function, including reproductive systems. Move outside the human body and you will see creatures that are only one cell in size which means they must perform all the basic functions for life. Truly amazing.
Which process develops a detailed description of the functions that a new information system must perform?
Systems design
Do all human cells function in the same way?
They are have basic sorts of functions in that they have a nucleus and other organelles. But beyond that they look and act differently according to what they must do. Nerve cells, muscles cells, skin cells and other are are different. You could tell them apart by using a microscope.

How do white and red blood cell differ in structure?
white and red blood cells have 2 different shapes because they have 2 different functions in the body.
