why do we have different types of cells?

Answer 1

A cell, although possessing tremendous potential, can't quite survive well in a large multi-cellular organism such as humans if it activates all those different functions.

In multi-cellular organisms, it is of prime importance to differentiate cells into different specialties. Thus, the cells would be able to do their best in the roles assigned to them. Although having the same cell being able to move, eat, think and sense would be quite convenient, much of those functions would interfere with each other. For example, muscle cells that contract and help us move require a lot of space to put the fibres that are responsible for contraction. If you were to put, say, a bone cell (osteocyte) function into the muscle cells, the bones that form would ultimately block the muscle fibres from contracting.

And after all, the efficiency of each of the cells would be increased. A red blood cell carries much, much more oxygen without being forced to digest the food that you eat. In fact, if the red cell were to digest food too, it would use up a lot of the oxygen that it's supposed to be carrying, thus denying a lot of other organs and tissue in your body of precious oxygen.

Hope that wasn't too confusing. =p

Answer 2

Each cell has a specific function for our body...

If we have the same cells, then each of them would be doing the same thing...

We also need other types of cells to do other things for us...

Answer 3

A bt of a random question, yet here you go: eukaryotic cells (regularly occurring physique and plant cells) prokaryotic cells (Bacterial cells, commonly. they have tail-like structures and no nucleus) crimson blood cells (used for the replace of oxygen to tissues from the capillaries with haemoglobin) white blood cells (lymphocites) which comprise B and T cells that are used for the physique's immunity Root tip cellular = the place water first enters a plant from a gradient of water means Cortex cellular = from the basis tip persevering with to the xylum Pallisade cellular = cells interior of a leaf that comprise chloroplasts that use easy for photosynthesis Epidermal cellular = cells after the cortex cells that have water resistant casperian strips tissue cellular = a cellular that mixes with many different tissue cells to sort the muscle groups effectual?

Answer 4

As we do have different organs with different functions in our body we have different cells with different functions, depending on the requirement the cell composition vary....

Answer 5

Because evolution made more complex creatures, where each part of the body, is responsible for different function. To realise this functions we need many kinds of cells.

Answer 6

We have different types of cells since our body has different functions. Each type of cell corresponds to certain function... Your skin is epithilial (tightly fit) for microorganisms not to enter easily... :D

Answer 7

A cell, although possessing tremendous potential, can't quite survive well in a large multi-cellular organism such as humans if it activates all those different functions.

Answer 8

To perform different functions. You wouldn't want bone cells in your brain would you?

Answer 9

Before we are born, our cells specialize to be able to perform different tasks. Otherwise, we would be nothing but lumps of skin, or puddles or blood, etc.
