Vedclass · Answer

(B) The correct answer is $B$. Mature sieve tube elements in angiosperms are specialized cells that lose their nucleus,ribosomes,vacuoles,and other organelles at maturity to facilitate the efficient transport of food (phloem sap). Therefore,the statement that they possess a conspicuous nucleus and usual cytoplasmic organelles is incorrect. Microbodies (like peroxisomes) are found in both plant and animal cells. The perinuclear space (the space between the two nuclear membranes) acts as a barrier between the nucleoplasm and the cytoplasm. Nuclear pores are complex structures that regulate the movement of $RNA$ and proteins between the nucleus and the cytoplasm in both directions.
