What protects the nucleus in a cell?
The nuclear membrane, also known as the nuclear envelope, surrounds the nucleus, protecting it and regulating the passage of materials in and out of the nucleus. It is a double membrane structure with pores that control the movement of molecules like proteins and RNA. Additionally, the nuclear lamina, a network of proteins, provides structural support to 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
Why does every plant cell have a nucleus?
Every plant cell has a nucleus because it contains the genetic material (DNA) needed for essential cellular functions such as growth, reproduction, and metabolism. The nucleus serves as the control center of the cell, regulating gene expression and coordinating various cellular processes.
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
Does a flatworm have a nucleus?
Yes, flatworms, like all other multicellular organism are eukaryotic. Prokaryotes are cells that lack a nucleus and they are usually free living. It is true that prokaryotes lack a cell wall.
Who discovered free-living cells and how?
Antonie van Leeuwenhoek is credited with discovering free-living cells using his single-lens microscope in the 17th century. He observed various microorganisms, including bacteria and protozoa, in samples of water and other materials.
Why would placing a cell nucleus inside a nucleus- free egg cell enable the egg to begin dividing?
Placing a cell nucleus inside a nucleus-free egg cell enables the egg to begin dividing because the introduced nucleus carries the genetic information necessary for cell division. The nucleus contains the DNA that instructs the egg cell to start dividing and developing into an embryo. This process, known as somatic cell nuclear transfer, reprograms the egg cell to start cell division by activating the genes in the introduced nucleus.
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.
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 the rough ER do in the plant cell?
i think it helps the nucleus be more free of its self.
What does rough ER in a plant cell do?
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.
Single cell pathogen with no nucleus?
The single cell pathogen with no nucleus is a prokaryotic organism. Prokaryotes, such as bacteria, lack a membrane-bound nucleus and their genetic material is found free-floating in the cytoplasm. This simple cell structure allows them to replicate quickly and adapt to various environments.
What are cells with and without a nucleus called?
Cells with a nucleus are called eukaryotic cells, while cells without a nucleus are called prokaryotic cells. Eukaryotic cells have their genetic material enclosed within a membrane-bound nucleus, whereas prokaryotic cells have their genetic material free-floating in the cytoplasm.

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.
What three things are in all cells?
I guess a Nucleus, Nucleolus and cytoplasm?
