Question

Which one of the following statement pertaining to plant structure is correct :

• A. Cork lacks stomata but lenticels carry out transpiration
• B. Passage cells help in transfer of food from cortex to phloem
• C. Sieve tube elements possess cytoplasm but no nuclei
• D. The shoot apical meristem has a quiescent centre

Answer 1

The correct option is C Sieve tube elements possess cytoplasm but no nuclei

Sieve elements' main function includes transporting sugars over long distances through the plants and they are by acting as a channel. Sieve elements elongate the cells containing sieve areas on their walls. Sieve elements are typically containing cytoplasm but lack a nucleus and contain none to a very small number of ribosomes.

So, the correct answer will be Sieve tube elements possess cytoplasm but no nuclei.

The correct option is C.
