Practice question
Question
Which phloem cell lacks nucleus at maturity?
Explanation
Go with C — Sieve tube element. Under PHLOEM TRANSLOCATION, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Companion cell; B) Phloem parenchyma; D) Transfer cell. When two options sound similar, choose the one that matches the textbook definition most tightly.
