Analisis SPM Cikgu Heery:

This question was never asked in SPM, but the labels are prominently shown in reference books. So, you need to know their basic features & functions only.

Soalan ini tidak pernah ditanya dlm SPM, tetapi label makronukleus & mikronukleus sering diketengahkan dlm buku rujukan. Maka, anda perlu tahu ciri & fungsinya secara ringkas shj.
