CCell wall material such as cellulose fibres
DLipid bilayers seen in the plasma membrane
Answer & Solution
Correct answer: A. Ribosomal RNA needed to build ribosomes
1. The chapter says each nucleus has at least one nucleolus.
2. Table 2.1 lists its function as producing ribosomes and storing RNA.
3. Ribosomal RNA later forms ribosomes in the cytoplasm.
4. So option A is correct.
