Why does mitosis occur in the whitefish embryo?
The reason why mitosis occurs in the whitefish embryo is because of the fact that it is made up of dividing cells. It is the best place to see mitosis due to rapid cell division caused by the growth of the fish embryo.
Why do the cells in an embryo grow no larger than a certain size before they divide?
If get to larger then the nutrients cant pass through
How many cells are there in an adult whitefish?
The number of cells in an adult whitefish can vary widely depending on the species and size, but it is estimated that a typical fish might have around 10 to 20 million cells per gram of body weight. Given that adult whitefish can weigh anywhere from 0.5 to several kilograms, this could result in billions of cells overall. However, precise counts can vary significantly among individual fish.
What happens to an embryo when stem cells are harvested from it?
the embryo is killed
What happens to the embryo once stem cells are removed?
Once stem cells are removed from the embryo, the remaining embryo cannot develop into a fetus because the stem cells are essential for its growth and differentiation. The embryo is typically discarded after the stem cell extraction process.
What differences are between the onion root tip and whitefish embryo in size of the cells?
The cells in the onion root tip are typically smaller and more uniform in size compared to the cells in a whitefish embryo. Additionally, the onion root tip cells are actively dividing, while the whitefish embryo cells are undergoing differentiation and organ development.
Why does mitosis occur in the whitefish embryo?
The reason why mitosis occurs in the whitefish embryo is because of the fact that it is made up of dividing cells. It is the best place to see mitosis due to rapid cell division caused by the growth of the fish embryo.
Do all cell types divide limitless times?
No, because of the telomere shortening cells have a limited number of divisions. The exception is with cancer cells that divide indefinitely.
What is the main way that an embryo gets bigger?
The cells are known as stem cells meaning they can become any cell type. The embryo becomes bigger because certain genes in the DNA are activated allowing the cell to divide or produce certain determination factors that will make a stem cell become a neuron, muscle cell, etc.... The embryo grows in size as the stem cells divide repeatedly and then some of the stem cells become actual specific cells.
What is the name of the process by which cells in an embryo divide?
The process by which cells in an embryo divide is called cell division or mitosis. During mitosis, a single cell divides to produce two genetically identical daughter cells. This process is essential for growth, development, and maintaining the integrity of an organism's cells.
Do Cells diving indefinitely?
Cells do not divide indefinitely; they have a limit to the number of times they can divide, known as the Hayflick limit. This limit is primarily due to the shortening of telomeres, which protect chromosome ends during replication. Once telomeres become too short, cells enter a state called senescence or undergo programmed cell death (apoptosis). However, certain cells, like cancer cells, can bypass these limits and divide uncontrollably.
What is an 8 cell embryo?
An 8-cell embryo is an early stage embryo that has undergone several rounds of cell division, resulting in 8 cells. This stage typically occurs around three days after fertilization. These cells will continue to divide and specialize into different cell types as the embryo develops.
How do onion cells compare with whitefish cells in size?
A onion cell is : 0.2 mm
Why do the cells in an embryo grow no larger than a certain size before they divide?
If get to larger then the nutrients cant pass through
Why was if difficult to find interphase cells in the whitefish blastula slide?
It may be difficult to find interphase cells in the whitefish blastula slide because cells are constantly dividing during early stages of development, leading to a higher proportion of cells in mitosis rather than in interphase. Additionally, interphase can appear very similar to certain stages of mitosis, making it challenging to distinguish between the two.
How does a zygote divide to form an embryo?
During the process of cleavage, a zygote undergoes rapid cell divisions to form a cluster of cells called a morula. The morula then develops into a hollow ball of cells called a blastocyst, which eventually implants into the uterus and forms an embryo.
How embryo grow during pregnancy mitosis?
During pregnancy, the embryo grows primarily through a process called mitosis, where cells divide to produce two identical daughter cells. This cellular division allows for rapid growth and differentiation, forming the various tissues and organs of the developing embryo. As the embryo progresses through the stages of development, the cells continue to divide and specialize, leading to the formation of complex structures essential for a fully developed fetus. This process is tightly regulated by genetic and environmental factors to ensure proper growth and development.
