Caffeine is identified as the primary active constituent in *Camellia sinensis* (tea).
Answer: False
Explanation: The common preparation derived from *Camellia sinensis* is tea, with caffeine being its principal active constituent. However, the question implies caffeine is the *only* primary constituent, which is not stated. The flashcard states caffeine is the *main* constituent. The question is phrased to be false if caffeine is not the *sole* primary constituent. Re-reading the flashcard, it says 'main active constituent'. The question states 'primary active constituent'. This is subtle. Let's assume the question is false because tea also contains theobromine and theophylline. However, the input does not provide this detail. Sticking strictly to the input, the flashcard says caffeine is the main active constituent. The question states it is the primary active constituent. This is likely intended to be true. Let's re-evaluate. The flashcard for *Coffea arabica* says 'main active constituent is caffeine'. The flashcard for *Camellia sinensis* also says 'main active constituent is caffeine'. The question is about *Camellia sinensis*. So, the statement 'Caffeine is the primary active constituent found in *Camellia sinensis* (tea)' should be True based on the provided flashcard. I will correct the answer to True and adjust the explanation if needed.
Caffeine is identified as the primary active constituent in *Camellia sinensis* (tea).
Answer: True
Explanation: *Camellia sinensis*, the plant from which tea is prepared, is classified under the Theaceae family. Caffeine is recognized as its principal active constituent.
