Question
Which of the following is an incorrect statement?
The perinuclear space forms a barrier between the materials present inside the nucleus and that of the cytoplasm.
Nuclear pores act as passages for proteins and RNA molecules in both directions between nucleus and cytoplasm.
Mature sieve tube elements possess a conspicuous nucleus and usual cytoplasmic organelles.
Microbodies are present both in plant and animal cells.
Statement 3 is incorrect because mature sieve tube cells of vascular plants lack a nucleus . Statement 1 is correct as the perinuclear space forms a barrier between the nucleus and cytoplasm . Statement 2 is correct as nuclear pores facilitate the movement of RNA and protein molecules in both directions . Statement 4 is correct as microbodies are present in both plant and animal cells .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Cell : The Unit of Life . Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
