Plant Behaviours:
1. - Some plants know when the sun will rise. Sunflowers are a good example of exhibiting this behavior called "Circadian Rhythm."

5. - A plant can distinguish their own roots from another plant's.

2. - Body language is a behavior most commonly associated with animals, even though we do it too.
3. - Territorial/'Defensive' behaviors are common, such as marking and hostility when another animal trespasses into their domain.
4. - Certain behaviors are exhibited to attract/court mates, such as birds singing songs or chemicals being thrown off to lure in a partner.

6. - Annual cycles, such as migration and hibernation.
7. - Animals also have a circadian rhythm like plants, which aids in whether or not an animal exhibits the behavior of being nocturnal.
