what's the difference between all these chemistry's?

what's the difference between organic, inorganic, physical, biochemistry and just ordinary chemistry?

Organic chemistry is to do with molecules that have Carbon-hydrogen bonds.
Inorganic chemistry is to do with molecules that dont have C-H bonds
Physical chemistry is chemistry that overlaps with physics. Like the stuff on radiation- alpha, beta and gama radiation etc...
biochemistry is chemistry is the chemistry in living things, it deal with cells, proteins, biomolecules.

I dont really know what you mean by ordinary chemistry. All of the above are chemistry, they all work together, like different departments of the same company...

dfx-

Organic is usually C-H bonds, but not necessarily C-H, may be C-N or C-O

All the groups then subdivide down further (Electrochemistry, spectroscopy, photochemistry, analytical chemistry etc etc) under the total umbrella of Chemistry

so biochemistry is photosynthesis, respiration, the chemistry of digestion?

Sort of, biochemistry is more to do with the chemistry behind biomolecules, such as proteins, carbohydrates, lipids, nucleic acids.

So some genetics would be biochemistry. How proteins or lipids are make would also be biochemistry...
