Through what parts of the nucleus do materials enter and leave?
Nucleus is enclosed in double walled nuclear membrane. Nuclear membrane at certain distance have pores in them which are called nuclear pores. Nuclear pores are very selectively permeable.
Why don't prokaryotic cells have mitochondria?
Prokaryotes are primitive organisms that do not have membrane bound structures. They do not have a proper chromosome but have a circular double stranded molecule of DNA called the nucleoid that is not enclosed in a nuclear membrane.
What includeds the cytoplasm and the nucleus?
The cytoplasm consists of all of the contents of the cell inside the plasma membrane. The nucleus is an organelle found in eukaryotic cells, isnide its fully enclosed nuclear membrane, it containts the majority of the cells genetic materials.
Do materials move into the nucleus do pores in the nuclear membrane?
Yes, materials move into the nucleus through pores in the nuclear membrane.
What part of the cell is enclosed by it own membrane?
The nucleus is the part of the cell that is enclosed by its own membrane, known as the nuclear membrane or nuclear envelope. This membrane separates the nucleus from the cytoplasm of the cell and helps regulate the movement of molecules in and out of the nucleus.
What is the purpose of nuclear membrane?
Nuclear membrane separates nucleus from cytoplasm and controls movement of materials in & out of nucleus.
What are the structure nucleus?
The nucleus is found in eukaryotic cells and its enclosed by a membrane. Its structures include a double membrane and the nuclear lamina.
Is nuclear membrane found in prokaryotic cells?
No it does not, reason being prokaryotes do not contain a nucleus.
What allows materials to pass by the nuclear membrane?
Golgi
What is the nuclear pore used for?
The nuclear pores are tiny holes in the the nuclear membrane surrounding the nucleus of a cell, which allow the movement of solluable materials through the nuclear membrane, in and out of the nucleus.
The nuclear membrane is allowing materials to pass through?
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.The things that can easily move in and out of the cell through the membrane are gases, like oxygen and carbon dioxide, and water.
Define primitive nucleus and true nucleus?
A primitive nucleus is a simple type of nucleus found in some organisms, such as prokaryotes, that lacks a membrane boundary separating it from the rest of the cell. In contrast, a true nucleus is a well-defined structure enclosed by a nuclear membrane found in eukaryotic cells, containing the genetic material and serving as the control center for the cell's activities.
