By "big", I assume you mean something on the order of 1 gallon or 4 liter. It is recommended that if you must carry chemicals stored in big bottles that you use a carrier designed for that purpose that has a handle, holds the bottle securely, is resistant to breakage (think metal or thick plastic) and that can contain the liquid if the carrier is banged into something or dropped with enough force to somehow break the bottle inside. Most of the major suppliers of bottled chemicals sell carriers designed for this purpose. They may just look like a bucket or may have a lid that snaps over the top. Some of the carrier lids have a hole that the neck of the bottle can poke through.
Chemical reagent bottles must be carried carefully. You have to first name the bottle with the reagent and paste the safety labels such as flammable. One can put the bottle in a safety, closed container if they want to carry the bottle out of the lab. If the reagent is not harmful to human or environment you can carry without the container.
To ensure no other chemicals get into the bottle and react with the solid you are trying to use.
They are kept tightly closed so there is less chance of contamination and if the bottle gets knocked over, its contents will not spill.
Coenzymes are made of mostly carbon molecules. These molecules get used and reused to carry various groups of chemicals to other enzymes.
Yes, the bottles are made of plastic.
There is no need to keep water in colored bottles and many people keep it in clear bottles. Some find colored bottles aesthetically pleasing and choose to use them for that reason.
Because there are really bad chemicals in plastic. Don't freeze water bottles or leave them out in the sun because the chemicals leak into the water that you consume.
Because glass is mostly inert, that is most chemicals don't attack it.
Dark bottles are used for chemicals sensitive to UV or some visible light.

Now that depends entirely on how big the bottles are.
Of course you do. There are even small bottles adapted for it. Of course you do. There are even small bottles adapted for it.
Nalgene lab bottles are mainly used to carry chemical liquids for laboratory/industrial use. For example, they can carry solvents, lab samples, and reagents.

Sustainable water bottles come in many forms from a number of different companies. Companies like Sigg and TapIt make bottles out of sustainable materials which do not leach chemicals into the water.
no, but watch what plastic bottles you re-use... some plastic bottles breakdown over time and the chemicals release into the liquid inside
