Specialized cells typically do not undergo mitosis because they have differentiated into specific functions and often exit the cell cycle, entering a quiescent state known as G0. This differentiation process involves changes in gene expression that lock them into their specialized roles, making them less likely to divide. Additionally, many specialized cells, like neurons or muscle cells, have a limited capacity for regeneration and are designed to maintain their function rather than proliferate.

Why pea root cells and salamander kidney cell takes the same for mitosis?
Pea root cells and salamander kidney cells take the same amount of time for mitosis because they both undergo similar stages of cell division, including prophase, metaphase, anaphase, and telophase. The duration of mitosis is typically consistent across different cell types in a species due to the regulated control of cell cycle checkpoints and the coordination of cellular machinery involved in mitosis.
What types of cells divide the least often?
Answer: The internal lining of your digestive tract. Explanation: The internal lining of your digestive tract receives a lot of wear and tear. As a result, cells that line your stomach and intestine are replaced every few days. In contrast, cells that make up the rest of your intestine (mainly smooth muscle) and many of your internal organs, such as lungs, kidney, and liver, divide only occasionaly, in respons to injury or cell death.
Does longitudinal splitting of chromosomes occur in mitosis?
No, longitudinal splitting of chromosomes does not occur in mitosis. During mitosis, chromosomes condense and align along the metaphase plate before being separated into two daughter cells. Longitudinal splitting can occur during meiosis I to produce haploid daughter cells.
What is nuclear division in eukaryotic cells in which each cell receives a copy of the original chromosomes?
mieosis.
Does mitosis allow the zygote body to grow?
The zygote is formed when two sex cells join to become haploid. It is at this stage that the zygote begins to split and make more cells. It keeps doing this for 5 days until it is called a blastocyst, which is a ball of cells. After this point, the blastocyst is called an embryo or fetus. The embro continues to make cells which eventually become specialised, like skin cells and muscle cells. It doesn't have anything to do with conservation of mass, just splitting and making thousands of new cells until the zygote becomes a baby.

Animals with radial symmetry get information?
i dont know the answer but i think its from specialized cells
How do you think small injuries to the skin heal?
I dont think, I KNOW! the cells that make up the human body continually divide by a process called mitosis. eventually, enough cells will have divided to fill up the hole in the skin. if you want to learn about mitosis, please visit http://en.wikipedia.org/wiki/Mitosis

What cells do animals have that plants dont?
Animals have specialized cells such as nerve cells, muscle cells, and blood cells that are not found in plants. These cells are responsible for functions like movement, coordination, and transportation of nutrients and oxygen throughout the body.
Do phloem cells contain chloroplasts?
No, phloem cells do not contain chloroplasts. Chloroplasts are typically found in plant cells that are involved in photosynthesis, such as leaf cells, while phloem cells are specialized for transporting nutrients, such as sugars, throughout the plant.

Can ducks produce chlorophyll?
No, only plants, algea, photosynthetic protists, and cyanobacteria undergo photosynthesis. Ducks are animals, so they have animal cells. Animal cells are do not have the organelles possible for photosynthesis.
What are two benefits of multicellular organisms having some specialized cells rather then all the cells being the same?
Specialized cells allow for division of labor within the organism, leading to increased efficiency and functionality. They also enable multicellular organisms to perform complex functions and adapt to diverse environments.
Why is it important for cells of multicellular organisms to undergo mitosis?
Cells of multicellular organisms (most plants & animals) go through mitosis in order to increase the number of cells in the body so that the body may develop initially, develop in later stages of life, and repair itself. The latter function, in most plants and some animals, may include regenerating (re-growing) a lost body part, such as an arm of a starfish. Unicellular organisms (e.g. bacteria, yeast, some fungi) undergo mitosis as their means of reproduction. Instead of "having children" or "laying eggs" the single-celled organism simply divides itself into 2 single-celled organisms. Meiosis is undergone by male germ cells in species which reproduce sexually (rather than asexually) in order to form sperm or pollen cells and by germ cells of females of the same species in order to form egg cells. When the sperm and egg (or pollen and egg) unite then a new cell with the same whole number of chromosomes as the parents is formed and this new cell develops into an individual of the species
