Oats are eaten by humans as oatmeal or rolled oats, and as feed for livestock such as cattle. in order for an oat plant to make the part we eat (the seed), it must flower and be pollinated. typically, oat plants flower when days are lengthening (i. e., late spring to early summer). what is the best classification for oat plants

The answer is Short night.

Explanation:

Oat is an example of a short night plant. Short night plants are also called long day plants, their flowering is induced by long days. Their plants flower when they are exposed to day length longer than the critical minimum requirement (i.e the days are longer than the critical day length). They usually flower in the spring or early summer. Their flowering can also be induced if the plants are exposed to short light period with still shorter dark period. Some other examples include; Barley, lettuce, wheat.
