Why is fire a nonliving organism?
Fire is not a living organism because it has no cells. living things need to: * Need air * Need energy * Produce Waste Products * be able to move by themselves * Respond to changes in the environment * Grow as it ages * Have cells * Reproduce there is some of these things that fire does not have or cant do.

Why do organisms grow larger by adding more cells?
If I diamond cracks can I repair it or do I need to replace it?

Why do mutations make organisms different from one another?
All the cells in a body have a specific function and purpose and have all developed themselves to be the best they can for that purpose (for example, muscle cells will need to move a lot and so they need a lot of ATP (energy) from the mitochondria whereas a cell somewhere else might need less mitochondria and more ribosomes to make proteins for growth). If there is a mutation in one of these cells it means that the cells function is no longer specific to what it was before, as the mutated cell replicates there are more and more copies of the mutated cells all serving a different function to the original one which makes them different to the organism with the original cells. (Thats just the changing of cells in one organism that could then be passed onto an organism of the same species - bt would still be differen). If the DNA mutates it will change the way all the bases on the DNA fit together - because DNA is what makes something what it is, a mutation here will cause the organism to change. This organism will then breed more and the genes will be passed by meiosis onto the daughter cells of the organism.
What does mitosis create?
Mitosis creates TWO new cells, which are used for growth and repair. Each of these new cells has the same number of chromosomes as the parent cell, 46 and it happens to reproduce and replace damaged cells and to allow an organism to grow. Im doing the science gcse exam with it in today so i need to know it :D

Why are specialized cells dependent on other specialized cells?
Specialized cells are dependent on other specialized cells because they need to live off other cells otherwise specialized cells wouldn't exist. Every specialized cell is designed to carry out a special function, there for we need a bunch of different specialized cells for the entire organism to survive.

How does the number of cells in a multicellular organism change as an organism grows?
individual cells grows in size, but there are limits to the size that cells can reach. cells need a high ratio of surface area to volume in order to function. as a cell grows, that ratio decreases. when the cell divides into two smaller cells, the ratio of surface area to volume for each cell increases.

Why is cellular differentiation a nessasary process in a developing multicellular organism?
because the in cellular differentiation, the cells can be water they need to be, the all don't have to be the same thing. So in a multicellular organism, there needs to be cells that can do multiple things so that the organism can work well. well that is what i think (I am only in 7th grade!!!) hope it helps :)
