The nucleolus is a compact structure present in the nucleus of fungal cells and all other eukaryotic cells. The nucleolus is not enclosed by a membrane. Nucleolar organizer present in the nucleolus contains the instructions for the synthesis of ribosomal RNAs.
Ribosomal proteins are synthesized in the cytoplasm. The ribosomal proteins are transported from the cytoplasm into the nucleolus. Assembly of ribosomal proteins and ribosomal RNAs to make ribosomal subunits occur inside the nucleolus which then enters cytoplasm to carry out protein synthesis.
active transport uses energy from ATP which is not found in the nucleus. so we know it uses energy which is not it's own and ATP is not apart of the nucleus so that leaves c
The receptor is the sensing component that monitors and responds to changes in the environment, either external or internal. Receptors include thermoreceptors, and mechanoreceptors.
