Final answer:
The nucleus, the cell's command center, interacts with other organelles through the nuclear envelope, which has pores allowing material exchange. It houses DNA and directs protein and ribosome synthesis.
Step-by-step explanation:
The nucleus interacts with other organelles by serving as the command center of the cell, where it stores the genetic instructions. The nucleus is enveloped by a nuclear envelope, which consists of two lipid bilayers with nuclear pores that regulate the entry and exit of materials. These nuclear pores allow proteins, RNA, and other solutes to move between the nucleus and the cytoplasm. The nucleus also directs the synthesis of ribosomes in the nucleolus and proteins in the cytoplasm.
Additional functions of the nucleus include housing the cell's DNA in the form of chromatin and orchestrating cellular activities by directing protein synthesis. Notably, some cells, like muscle cells, can be multinucleated whereas others, such as mammalian red blood cells, do not have a nucleus at all.
