The cell's ultrastructure, the detailed structure of the cell, has been studied with an electron microscope. Beam of electrons are focused by electromagnets so that a maximum magnification of about 500 000 times the real size of the specimen is possible.
The most important feature of the cell which can be identified from a cell's ultrastructure is the nucleus, which is about five micrometers in size. The nucleus contains chromosomes (genes made of DNA which control cell activities), separated from the cytoplasm by a nuclear envelope. A double membrane within the envelope contains small holes called nuclear pores (100nm in diameter) which allow the transport of proteins into the nucleus. DNA in the nucleus is continuously used to manufacture proteins.

The structure that house a eukaryotic cells DNA is known as the nucleus. The nucleus has a membrane that is similar to a cell membrane.
The largest structure in an animal cell is the nucleus. It houses genetic material (DNA) and controls the cell's activities.

Algal cells have a unique structure including a cell wall, cell membrane, chloroplasts for photosynthesis, a central vacuole, and a nucleus. The cell wall provides structure and protection, while the cell membrane controls the movement of substances in and out of the cell. The chloroplasts contain chlorophyll for photosynthesis, and the central vacuole stores water and nutrients. The nucleus contains the cell's genetic material.

Nucleus
The parts in the structure of nucleus are nuclear membrane, Nuclear pores, Nuclear plasm, Nucleoli, Chromatin.
Yes, the nucleus has an internal structure . It consists of nucleons, chromosomes,genes and DNA. With a definable internal structure nucleus is the heart of a cell .

The structure that encloses the nucleus is called the nuclear envelope, which is a double membrane layer that separates the nucleus from the cytoplasm. It contains pores that allow for the exchange of materials between the nucleus and cytoplasm.
