INTERPHASE also known as the resting phase. In this phase chromosomes reproduce themselves (are held together by the centromere)and the cell starts to enlarge
PROPHASE - the nuclear membran breaks down, chromosomes shorten,the centrosome splits (each section known as the centriole) and moves towards opposite ends (poles) of the cell. Centrioles start to produce spindle fibers. Nucleus dissapears.
METAPHASE- the chromosomes are pushedto the middle (equator) of the cell by the spindle fibers
ANAPHASE- spindle fibers contrace (pull apart) and the centromere splits which causes the chromosomes to be pulled apart and move to opposite poles
TELEPHASE- the chromosomes reach the poles, the nuclear membrane reforms and the nucleus reappears the spindle fibers dissapear and the cytoplasm pinches in from the sides and eventually splits to form two new cells.
Plant cell division is like animal cell division in all other aspects, but unlike animal cell, a plant cell lacks centriole, by which spindle fibre produce during metaphase stage. But in plant cell, spindle fibre are produced from protein rich material, i.e. the pole.
During metaphase in cell division, a chromosome looks like a condensed and tightly coiled structure that is visible under a microscope. It appears as an X-shaped structure with two identical sister chromatids joined at the centromere.
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.
Centrioles are cylindrical structures composed of microtubules arranged in a specific configuration, which gives them a churro-like appearance under a microscope. This shape helps centrioles in organizing the microtubules of the cell's cytoskeleton and facilitating cell division.
One of the primary signals for cell division is the presence of growth factors that bind to specific receptors on the cell surface, initiating a cascade of intracellular events that drive the cell cycle progression. Additionally, internal signals like the cell's own regulatory proteins, such as cyclins and cyclin-dependent kinases, play a crucial role in controlling cell division.
When the mitotic cycle is completed, they look pretty much identical.
:Mitosis is the cell division which did not divided the cell.: Reduction Division is the cell division which divided the cell into half.

Hormones function as chemical messengers that can stimulate or inhibit cell division by binding to specific receptors on target cells. Some hormones, like growth factors, promote cell division by activating cell cycle progression, while others, like anti-growth factors, suppress cell division to maintain homeostasis. The balance of these hormonal signals plays a crucial role in regulating cell division and maintaining tissue growth and repair.

Yes, the rate of cell division can vary between different tissue types within an organism. Some tissues, like epithelial tissues, have high rates of cell division for maintenance and repair, while others, like nervous tissue, have lower rates of cell division. The specific function and needs of each tissue type determine its rate of cell division.

both cell division processes
Genes such as cyclins, cyclin-dependent kinases (CDKs), and tumor suppressor genes like p53 play essential roles in regulating the proteins necessary for cell division. These genes ensure that the cell cycle progresses accurately by controlling checkpoints and cell division processes. Mutations in these genes can lead to uncontrolled cell division and contribute to conditions like cancer.
