Final answer:
The false statement about the nucleus is that it is the major site to synthesize ATP; ATP is synthesized in the mitochondria. The nucleus has a double membrane, is contiguous with the ER, contains the nucleolus, and has nuclear pores.
Step-by-step explanation:
Characteristics of the Nucleus
A student asked about the falsities regarding the nucleus of eukaryotic cells. To clarify, the nucleus does not synthesize ATP, which is the primary function of mitochondria. Here are the true statements about the nucleus:
- The outer lipid bilayer of the nucleus is continuous with the endoplasmic reticulum (ER).
- The nucleus has nuclear pores that allow materials to move between the nucleus and the cytosol.
- The nucleus is enclosed by a double membrane known as the nuclear envelope.
- Inside the nucleus, there exists a subcompartment called the nucleolus, the site where ribosomes are made.
The incorrect statement that the nucleus is the major site of ATP synthesis could be misleading; ATP is primarily synthesized in the mitochondria through cellular respiration. The nucleus is involved in the storage and replication of genetic material and the assembly of ribosomes within the nucleolus.
The nucleus is a double membrane-bound organelle that contains the genetic material of the cell. The outer lipid bilayer of the nucleus is contiguous with the endoplasmic reticulum, which allows for communication and exchange of materials between the nucleus and the cytosol through nuclear pores. The nucleus also contains a subcompartment called the nucleolus, which is involved in the synthesis of ribosomes.
