Why do fibre cells loose a nucleus at maturity though is a vital component of a cell?
Fibre cells, such as those found in plants, lose their nuclei at maturity to enhance structural efficiency and strength. This loss allows for more space to be filled with lignin and cellulose, which are crucial for providing rigidity and support. By sacrificing the nucleus, these cells can better fulfill their role in maintaining the integrity of the plant, especially in areas requiring strength and durability. This adaptation is a trade-off that prioritizes mechanical function over metabolic activity.

What cells lose their nucleus at maturity?
Red blood cells lose their nucleus at maturity. It is kicked out, lost or nuked (depending how you want to call it) to make more room for hemoglobin. The nucleus makes as much as possible, packs it in tight and then is lost. Because the nucleus is gone, the cell can not repair itself and will get tattered and rather worn out in about 120 days. It will be recycled.
Do xylem vessel have nucleus?
No, xylem vessels do not have a nucleus. Xylem vessels are composed of dead cells at maturity, which allows them to efficiently transport water and minerals from the roots to the rest of the plant. The absence of a nucleus and other organelles in these cells maximizes the space available for water conduction.
Which of these plant cells is alive but has no nucleus?
Plant cells that are transitioning from parenchyma to collenchyma. The transition process sheds the nucleus as the cell walls become thickened and the cell beings to die. This is the process that is responsible for tree bark.
Where is the DNA in the porkaryotic and eukaryotic cells?
In eukaryotic cells, DNA exists within the nucleus. In prokaryotic cells, DNA is located as a circular chromosome just in the cytoplasm. There is however a distinct region though but IT IS NOT A NUCLEUS.
Can you see evidence of a nucleus in each prokaryotic cell?
No, prokaryotic cells do not have a well-defined nucleus. Instead, their genetic material is typically found in a region of the cell called the nucleoid, which is not membrane-bound like the nucleus found in eukaryotic cells.
Which of the following types of blood cells does not have a nucleus at maturity?
red blood cells
Are lipids a major component of the cells nucleus?
No. Lipids are an essential and major component of the cell membrane

Do bacterial cells have a nucleus?
bacteria do not contain a nucleus. they have their genetic material in contact with the cellular component. there is no nuclear membrane to enclose their nuclear material into a nucleus.they are devoid of compartmentalization i.e they do not have membrane bound oraganelles and as nucleus is a membrane bound organelle so it is absent. though their genetic material is still present but in contact with cytoplasm
What are cells that do have a nuclei?
Nucleus is an imp component of cell essential for survival . An organised nucleus appears in eukaryotes(except mammalian rbc and sieve tube cells of phloem) for the first time .Prokaryotes have an unorganised nucleus....
Do xylem vessel have nucleus?
No, xylem vessels do not have a nucleus. Xylem vessels are composed of dead cells at maturity, which allows them to efficiently transport water and minerals from the roots to the rest of the plant. The absence of a nucleus and other organelles in these cells maximizes the space available for water conduction.
What are cells with no nucleas called?
Prokaryotic cells do not have a membrane bound nucleus. They do have a nuclear area. Additionally, the mature human red blood cell lacks a nucleus. It excruded it's cell upon maturity. This allows it to carry more hemoglobin.
Which of these plant cells is alive but has no nucleus?
Plant cells that are transitioning from parenchyma to collenchyma. The transition process sheds the nucleus as the cell walls become thickened and the cell beings to die. This is the process that is responsible for tree bark.

What powerful genetic component is inside the nucleus of the cell?
DNA (Deoxyribonucleic Acid) is the most powerful genetic component and is located in the nucleus. DNA is a nucleic acid found in all living cells. DNA carries carries an organisms hereditary information.
Can you see evidence of a nucleus in each prokaryotic cell?
No, prokaryotic cells do not have a well-defined nucleus. Instead, their genetic material is typically found in a region of the cell called the nucleoid, which is not membrane-bound like the nucleus found in eukaryotic cells.
What are some examples cells divide rapidly some not at all after maturity?
Examples of cells that divide rapidly after maturity include skin cells, intestinal cells, and blood cells. Examples of cells that do not divide at all after maturity include neurons and cardiac muscle cells.
