I believe they are all C3 plants.
This means they take CO2 directly from the air to use in the Calvin cycle of photosynthesis.
grain
Yes. Oats are a certain type of grain. Other grains are flaxen, wheat or rice bran, and beet pulp.
corn wheat and rice are all a type of crop grown by farmers.
ss
The question is sorta confusing. Rice Semolina would the same as Rice flour but maybe made from a darker rice. Rice by itself is gluten free. However if ANY kind of wheat is involved (durum wheat is used for semolina type flour) then it would not be gluten free. Remember, wheat is wheat no matter what type and it will have gluten.
Type
Major food crops such as corn wheat and rice are staples
AFAIK, cereal was never used as ammunition. Some folks have used corn meal as a buffer in shotgun loading. <><><><> However, one company, Quaker Oats, DID use the term "Shot from Guns" to advertise their Puffed Wheat and Puffed Rice. But the "guns" were steam cookers, and the wheat and rice were not ammo- but cereal.
Rice and wheat smh :p
Wheat, rye, oats, barley, and hops are all warehouse stored grains.
Wheat rusts "eat" wheat. It's a type of fungus that grows parasitically on wheat and related plants.
Rice, corn, cassava, and sweet potato (in this order) are the most commonly found crops growing in Vietnam.
Barley, rye, oats, and wheat. Gluten can also be in natural and artificial flavor and caramel color. It may also be in maltoextrin, modified food starch, and is always in malt. It can be in a lot of other things too, I should know. I've had Celiac disease for almost three years. My mom and I did a lot of research and put a big binder of gluten free foods and brands together. I would recommend calling the company if you aren't sure about something. Great things you CAN eat are brown rice and quinoa. They make a lot of products with these ingredients as a base (i.e. brown rice bread, pasta etc..) Edit: Actually the oats themselves don't contain gluten but oats are generally contaminated in transport with wheat which is why we avoid oats. It is possible to get oats that have not been contaminated and are therefore gluten free. A long term study published in 2007 showed no detrimental effects on celiacs from eating these oats.
