What is the name of log-like structures that appear during cell division in animal cells and pull the chromosomes apart?
In meiosis or mitosis they are called spindle fibers which are "anchored" using centrioles.
What parts of chromosomes are visible in nondividing cells?
Congrition movement and Metamorphosis are seen in meiosis but not in mitosis
What would be the role of the centrioles?
During Mitosis, during metaphase, the centrioles grow spindle fibers which attach to the chromosomes located currently on the centrosome. They then pull one half of the chromosome to their side of the cell, this process is called anaphase. They then disappear.
What do centrioles produce?
The centrioles produce microtubules called spindle fibers, which push the centrioles apart as they grow.
Do the chromosomes separate once in both mitosis and meiosis?
No. In mitosis the chromosomes separate once. In meiosis, in anaphase I, homologous chromosomes separate, but are still attached as sister chromatids. In anaphase II, the sister chromatids separate. So there are two chromosome separations in meiosis.
What are 3 things Meiosis and Mitosis have in common?
Meiosis and Mitosis both use centrioles, they both have the same process(except for a few other steps in Meiosis) and they both split cells.
Do animals have a centroile?
Centrioles are found in animal cells and help to organize the assembly of microtubules during cell division. Centrioles replicate during the interphase stage of mitosis and meiosis. Centrioles called basal bodies form cilia and flagella.
In mitosis the little green T shaped things on a cell is called?
the heart well in mitosis it is called centrosomes
What happens during metaphase in meiosis?
chromosomes move to the middle of the cell. mitotic spindles from the centrioles attach to the centromere of the chromosome

What parts of chromosomes are visible in nondividing cells?
Congrition movement and Metamorphosis are seen in meiosis but not in mitosis
What are the functions of centriole?
Centrioles are two small organelles every animal cell contains, and their function is to help the division of the cell. This means they are involved in the two very important functions of Mitosis and Meiosis. They are located near the nucleus.
What would happen if the cell did not contain centrioles?
mitosis & meiosis would not proceed normally. the centrioles are responsible for helping form the spindles which pull the chromatids to either side of the dividing cell. so if u didn't have the centrioles (form the asters) then the divided cells would not have an equal numbers of chromosomes at the end. http://dictionary.reference.com/browse/centrioles see second def. listed

A tiny structure located in the cytoplasm near the nuclear envelope is an?
centrioles
What phase of meiosis does each replicated chromosome pair with its corresponding homologous chromosome?
Prophase 1 is the phase of meiosis ll when the homologous pairs combine. It is also when centrioles seperate, spindle fibers are formed, the nuclear envelope disappears, and the chromosomes become visible.
Why might plant cells not need centrioles for mitosis or meiosis?
The centriole's function is currently unknown and because of this, it is considered to be useless. Plants don't have centrioles, and it functions just fine as a plant. Centrioles are probably unnecessary in animals as well.
