**Question Stem:** 如图为变形虫细胞分裂不同阶段的示意图。下列排序正确的是 **Image Description:** The image displays four diagrams illustrating different stages of amoeba cell division, labeled ①, ②, ③, and ④. - Diagram ① shows an amoeba cell with a slightly elongated nucleus containing two distinct clumps of chromatin. The cell outline is irregular. - Diagram ② shows two separate daughter amoeba cells, each with a single nucleus. - Diagram ③ shows an amoeba cell with a single, round nucleus. The cell outline is irregular. This represents the initial stage before division begins. - Diagram ④ shows an amoeba cell that is elongated and constricted in the middle, with the duplicated nucleus starting to separate towards opposite poles. The nucleus appears elongated or dumbbell-shaped. **Options:** A. ①→②→③→④ B. ②→④→①→③ C. ③→①→④→② D. ④→③→②→① **Other Relevant Text:** 细胞分裂就是一个细胞分成两个细胞的过程。 变形虫属于单细胞动物, 细胞分裂时, 细胞核先由一个分成两个, 随后, 细胞质分成两份, 每份各含有一个细胞核。最后, 在原来的细胞的中央, 形成新的细胞膜, 于是一个细胞就分裂成为两个细胞。可见正确排序为: ③→①→④→②。
