because stem cells in immature animals can change into virtualy anything making them more unstable
The differentiation of stem cells is not limited to immature animals. Stem cells have the ability to differentiate into specialized cell types in both immature and mature animals. However, the potential and efficiency of differentiation may vary depending on the developmental stage and the specific type of stem cell. In general, embryonic stem cells have a greater capacity for differentiation compared to adult stem cells, which may have more limited potential to differentiate into specific cell lineages.
No, mitosis does not occur in the phloem. Mitosis is the process of cell division, and in the phloem, specialized cells called sieve elements are responsible for transporting sugars. These sieve elements are formed via a process called differentiation, not mitosis.
Sperm cells have an immature stage in the testes and maturation occurs as the sperm move through the testicular system. There can be multiple reasons for ejaculate to contain immature sperm cells. The mechanical reason is high frequency of intercourse. Another reason for failure would occur in the epididymis where the Sertoli cells facilitate maturation. Causes can be adult mumps, hormonal issues, drugs/medication, radiation, genetic anomalies and excess heat.
Cell differentiation is important in multicellular organisms because it ensures that every function required by the body is able to occur. For example, nerve cells are specialised to transmit information, red blood cells are specialised to carry oxygen. (If no cell differentiation occurred in multicellular organisms all cells would be the same and no specialised functions could occur.)
Cell differentiation. DNA contains the code to form any type of cell in the human body. At first, the cell just replicates everything, then it starts to differentiate. Some parts of the code become inactive and other parts become active. This is how it goes from a bundle of cells to creating bones, liver, lungs, heart, brain, etc.
Differentiation occurs several times during the development of a multicellular organism. The organism changes from a simple zygote to a complex system of tissues and cell types.
Glycolysis occurs in the cytoplasm of animal cells.
In people, differentiation occurs during the fetal development in the uterus.
Differentiation occurred in other inner planets, besides Earth.

Yes.
The planet must have a molten interior

They all rely on mitosis in order to occur.

Because diffusion is how chemicals travel in and out of the animal's cells. If diffusion didn't occur then the animal would die.
Cell differentiation occurs numerous times during the development of a multicellular organism. All organism changes from a single zygote to a complex system of tissues and cell types.
