Answers (1)
Sieve elements' major function includes transporting sugars over long distances through plants by acting as a channel. Sieve elements elongate cells containing sieve areas on their walls. Sieve elements typically contain cytoplasm but lack a nucleus and contain none to a very small number of ribosomes.
So, the correct answer is 'Sieve tube elements possess cytoplasm but no nuclei.' Hence, the correct answer is option 3.
