What protects the nucleus in a cell?
Nuclear membrane is a thin membrane surrounds and protects the nucleus.
Prokaryotes are single-celled organisms that lack a?
Prokaryotes don't have a nucleus - their DNA is floating free in the cell cytoplasm. in other words they lack a Nucleus
What does prokaryotic and eukaryotic mean?
A prokaryotic cell is normally a bacteria. A prokaryotic cell does not have a membrane around it's nucleus, it has loops of DNA free in its cytoplasm. A eukaryotic cell is any cell with many organelles (other parts which help it function) and a membrane-bound nucleus. The nucleus is the key difference- if it has a membrane, it is Eukaryotic/a Eukaryote. If not, it is Prokaryotic/a Prokaryote.
Describe the role of the nucleus in the cell?
- The nucleus contains the DNA. It is the site for replication and transcription. The most important processes of a cell.-Attached to the nucleus outside membrane, there are the ribosomes (found free in Cytoplasm and on the RER as well). Ribosome will attach to mRNA when mRNA pass through nucleus pore to reach the cytosol. Ribosome are the indispensable complex for translation
How do chromosomes function in a prokaryotic cell?
In a prokaryote there is no designated nucleus and the genetic mass is free floating. As there is one chromosome it is circular.
Who discovered free-living cells and how?
leeuwenhoek first discovered the free living cell . he observed these cells with the help of primitive microscope in pond water
Why would placing a cell nucleus inside a nucleus- free egg cell enable the egg to begin dividing?
The cell nucleus contains the information (instuctions) to do so.
What protects the nucleus in a cell?
Nuclear membrane is a thin membrane surrounds and protects the nucleus.
What three things are in all cells?
I guess a Nucleus, Nucleolus and cytoplasm?
A cell would function without a nucleus explain your answer?
Most bacteria don't have a nucleus and they function using free floating DNA within the cell.
Prokaryotes are single-celled organisms that lack a?
Prokaryotes don't have a nucleus - their DNA is floating free in the cell cytoplasm. in other words they lack a Nucleus
What will happen to a cell if its nucleus is removed free download notes?
If a cell's nucleus is removed, it will eventually die because it will not be able to carry out protein synthesis, which is essential for life.
What does rough ER in a plant cell do?
i think it helps the nucleus be more free of its self.
What does the rough ER do in the plant cell?
i think it helps the nucleus be more free of its self.
Why is nucleus missing from red blood cell?
It is a genetic adaptation; without nucleus more space for hemoglobin is free. And hemoglobin is the carrier of oxygen.

Why is it important for the cell membrane to be selectively premeable?
It makes it harder for viruses and free radicals to reach the nucleus.
