What part of the cell directs the work of the cell?
the cell
Cell division has the purpose of?
Cell division serves the purpose of growth, development, tissue repair, and reproduction in organisms. It allows for the formation of new cells to replace old or damaged ones, as well as for the production of offspring in organisms that reproduce sexually.
What are some examples of internal and external signals that activate cell division?
Internal signals that activate cell division include growth factors and hormones such as insulin, while external signals include physical factors like cell-to-cell contact inhibition and chemical signals from neighboring cells indicating tissue repair or growth factors released by damaged tissue.
What serves as a control for cell metabolism and reproduction?
The cell cycle regulatory proteins, including cyclins and cyclin-dependent kinases, serve as controls for cell metabolism and reproduction. These proteins regulate various checkpoints in the cell cycle to ensure proper timing and progression of events like DNA replication and cell division. Dysregulation of these controls can result in abnormalities such as uncontrolled cell growth or cell death.
Difference between nuclear division and cell division?
Cell division is when a cell splits in two to make more cells, and the cycle is where the cell does all the other stuff. A full life span of a cell is cell cycle that include cell division+ cell death and cell division cycle is the process of a cell to divide into two.
What part of the cell directs the work of the cell?
the cell
What kind of cell division when the cell is not dividing?
:Mitosis is the cell division which did not divided the cell.: Reduction Division is the cell division which divided the cell into half.
Which organelle holds the DNA and is the control center of the cell?
The nucleus is the organelle that holds the DNA and serves as the control center of the cell. It regulates gene expression, DNA replication, and cell division.
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The kinetochore is the region of the chromosome that serves as the attachment site for microtubules during cell division. It is a protein structure that forms on the centromere of a chromatid. Kinetochore microtubules connect the chromatids to the mitotic spindle to aid in the separation of chromosomes during mitosis.
What function does the nucleus serve?
The nucleus serves as the control center of the cell, responsible for storing and protecting the cell's genetic material, such as DNA and RNA. It regulates gene expression, DNA replication, and cell division, playing a critical role in maintaining the overall function and characteristics of the cell.
What signal might be considered a growth stimulating signal for a yeast cell?
A growth stimulating signal for a yeast cell could be the presence of a favorable nutrient source such as glucose. When yeast cells sense the availability of glucose, they activate signaling pathways that promote cell growth and division. This signal triggers the cells to reprogram their metabolism to efficiently utilize the nutrient for energy and biomass production.
Cell division has the purpose of?
Cell division serves the purpose of growth, development, tissue repair, and reproduction in organisms. It allows for the formation of new cells to replace old or damaged ones, as well as for the production of offspring in organisms that reproduce sexually.
Cancer is marked by uncontrolled cell growth and division. Which factor in excessive amounts contributes to this development?
Uncontrolled meiosis
What does the neculeus in a plant cell do?
The nucleus in a plant cell houses the cell's genetic material (DNA) and is responsible for controlling the cell's activities, including cell growth, division, and protein synthesis. It serves as the cell's control center, regulating its functions and transmitting genetic information to new cells during cell division.
Do lysosomes initiate cell division in animal cell?
No, centrosomes initiate and regulate cell division in plants.In cell biology, the centrosomeis an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell as well as a regulator of cell-cycleprogression.Lysosomes ,better known as Suicide bags,use enzymes to destroy the other damaged cell organelles.
What is the area of a chromosome pair that attatches to a fiber stretching across the cell during cell division?
The area of a chromosome pair that attaches to a fiber stretching across the cell during cell division is called the centromere. The centromere plays a crucial role in ensuring equal distribution of genetic material to daughter cells during cell division, as it serves as the attachment point for spindle fibers that assist in separating the chromosomes.
When receptors are activated they generate?
When receptors are activated, they generate a signal that triggers a cellular response. This signal is typically transmitted through a series of molecular pathways within the cell, leading to a specific physiological outcome such as gene expression, muscle contraction, or cell division.
