Proteins. If your source of protein is from animals, that's called a "complete protein", if you're getting plant protein (beans, grains) you'll need to make sure to mix it up a bit getting the proteins from a few different sources so that you can get the complete protein.
Beans combined with a wheat product provide a whole protein source. Tofu, from soy, is also a good source.
The "complete protein" thing is kind of a myth with regard to human nutrition. All plant foods contain complete proteins.

Phototropism is responsible, is when the sun rays stimulate the plant at its vascular and cellular level allowing for it's stems cells to bend around towards following the light source (sun). As the plant bends around following the light source, the plant's stem side walls located farthest away from the light source elongate allowing for the plant to travel following the sun.
There are two major protein sources: Animal based proteins Plant based proteins Proteins are made up of amino acids. If a source has all the essential AAs, it is called complete protein. If a source does not consist of all the essential Amino Acids it is called incompete protein. A good source of protein is the one that provides with all the essential AAs. Mostly animal based proteins are complete proteins & a good source of essential AAs. Sources: Eggs, Milk, Meat (Beef, mutton, fish etc) In case of plant proteins combination method should be used in order to get all the essential Amino Acids. Example: Rice & lentil
Protein powders are concentrated sources of protein which supplement the calories which come from proteins. They are derived from various sources like plant and animal derived protein sources. Plant and animal derived protein sources include Whey Protein, Casein Protein and Soy Protein. Let us have a brief info about each of these protein derived from different sources.These are as follows-Whey Protein: It is milk derived protein and is considered the complete protein as it has essential amino acids. It is easily absorbed in blood and helps in protein synthesis.Casein Protein: It is also a milk derived protein and offers a good protein balance when taken in conjunction with whey protein. Casein protein is not absorbed that easily in blood.Soy Protein: It is a soy bean derived protein and acts as an excellent source of protein.
Rice (brown preferred) and Beans.

Although plant based proteins are often considered to be inferior to those of animals, Hemp seeds are considered to be a complete source of protein. Hemp will not get you high because they only contain mere traces of the psycho active compounds Hemp is known for.
