The type of cell that lacks a nucleus and other membrane-bound organelles is a prokaryotic cell. Prokaryotic cells are typically found in bacteria and archaea and their DNA floats freely in the cytoplasm.
A Mitochondria and C Nucleus. Eukaryotic cells have membrane-bound organelles like mitochondria and a nucleus, which are absent in prokaryotic cells. The Golgi apparatus and cell membrane are found in both eukaryotic and prokaryotic cells.
Prokaryotic cells do not have a nucleus. Instead, their genetic material is found in a region of the cytoplasm called the nucleoid.
A membrane-bound nucleus is a distinct organelle found in eukaryotic cells where the genetic material is housed. It is enclosed by a double membrane called the nuclear envelope, which separates the nucleus from the rest of the cell. The nucleus plays a crucial role in controlling gene expression and cellular activities.
The types of membranes lining cavities that communicate with the exterior of the body are mucous membranes. These membranes are found in areas such as the respiratory, digestive, urinary, and reproductive tracts, and they secrete mucus to protect and lubricate the tissues.
Mucous membrane
in the nucleus.
The skeletal system would not be lined with a mucous membrane. Mucous membranes are found in the respiratory, digestive, urinary, and reproductive systems to secrete mucus that helps protect and lubricate these cavities.
Any body area that has an outlet to the out side is covered in a mucous membrane: respiratory tact. digestive tract, urinary tract, even the membrane that surrounds the orbit of the eye (eye ball).
Nucleus
The nucleus is found in eukaryotic cells and its enclosed by a membrane. Its structures include a double membrane and the nuclear lamina.
The nucleus is found inside a lipid bilayer membrane that is very similar to the membrane around the entire cell. It is called the nuclear membrane.
