Tips
usage
Standard biology textbook term in middle school and high school. Sister terms to learn together: 细胞 (xìbāo, 'cell'), 细胞质 (xìbāozhì, 'cytoplasm'), 细胞膜 (xìbāomó, 'cell membrane'), 染色体 (rǎnsètǐ, 'chromosome').
memory
细胞 ('cell' = 'fine sac/bladder') + 核 ('core / nucleus / pit'). The same 核 appears in 核心 ('core'), 原子核 ('atomic nucleus'), 桃核 ('peach pit') — it's the 'core' of just about anything.
