Why is it more accurate to mitosis nuclear replication rather than cellular division?
In definision, mitosis is division of the nucleus and not the cell (cytokenesis is the division of the cytoplasm. Mitosis involves the the Prophase, Metaphase, Anaphase, and Telophase. These phases only replicate the nucleus and not the whole cell. Cytokenesis, however, involves the replication or sharing of all the other organelles. Have fun on the AP Bio Lab.
What is the difference between daughter cells produced by mitosis and daughter cells produced by mitosis?
Amitosis is nuclear division occurring without symmetry, and as such is a rather random type of division with without proper structure. Mitosis and Meiosis do differ in the number of daughter cells, mitosis with 2 and meiosis with 4. This, however, is also not a fair comparison, as mitosis and meiosis result in different types of cells.
How many minutes does inter-phase take in mitosis?
Interphase is not a part of mitosis; rather, it is the phase of the cell cycle that occurs before mitosis. It typically lasts much longer than mitosis itself, often taking several hours to days depending on the cell type. Mitosis, which includes prophase, metaphase, anaphase, and telophase, usually takes about 30 minutes to a few hours in total. Interphase consists of three stages: G1, S, and G2, during which the cell grows, replicates its DNA, and prepares for division.
Plant cells cannot undergo cell division because of their strong cell walls?
Although plant cells indeed have strong cell walls, they are still capable of undergoing cell division. Cell division in plants occurs through a process called mitosis, wherein the cell elongates and undergoes cytokinesis, resulting in the formation of two daughter cells. The presence of cell walls does not prevent cell division, but rather allows for rigidity and support in the plant structure.
What happens at the after cell division?
After cell division is completed, it remains for a rather long time in the resting phase.

How does the paramecium reproduces?
Paramecium reproduces through mitosis, since it is a single celled Eukaryote. I suppose it is not called "mitosis," but rather "asexual reproduction," but it uses the same processes.
Is spindle a organ in cell?
No, a spindle is a structure formed during cell division (mitosis) to help separate chromosomes. It is not an organ, but rather a network of microtubules that helps move and segregate chromosomes during cell division.
When do nuclear envelopes divide?
During cell division, the nuclear envelope doesn't really "divide", but rather it dissolves away to allow the chromosomes to line up to initiate metaphase.
Why do some scientists not think interphase is a phase of mitosis?
Some scientists do not consider interphase a phase of mitosis because interphase is the stage of the cell cycle where the cell prepares for mitosis, rather than actively dividing. During interphase, the cell undergoes growth, DNA replication, and preparation for division, but it does not involve the processes of chromosome alignment, separation, or cytokinesis that characterize mitosis. Therefore, interphase is seen as a preparatory phase rather than a part of the actual mitotic process.
Anaphase is the stage of cell division when the cleavage furrow first appears?
No, anaphase is the stage of cell division when the chromosomes are pulled and pushed apart and head to opposite polls of the cell. Infact Anaphase is the stage of nuclear division rather than cell division and cell division is achieved by cytokinesis which may be by cell plate formation (as in case of many plants) or by furrowing (as in case of animal cells).
What Cells are part of the Cell cycle but not a part of mitosis?
Sex cells, or germ cells; in females the eggs, and in males the sperm. They go through meiosis, and unlike in mitosis are only haploid, so they only have one copy of the genetic material, so that when they meet with another germ cell, they form a diploid zygote.

Why a better understanding of the mechanism of cell division may enable scientists to regenerate limbs?
It isn't a better knowledge of cell division, but rather, a better knowledge of cell differentiation that allows us the possibility of one day inducing limb or organ regeneration. We know a lot about mitosis, but not nearly enough about the signals that induce differentiation.
Where are compound starch grains found?
Cytoplasm and Caryoplasm.The nucleus is a rather conspicuous part of nearly every living plant cell. Its structure separated from the rest of the cell by the nuclear envelope, a membrane system that consists of two discrete membranes as can be seen on electromicroscopic images. The nuclear content is called the caryoplasm while that of the rest of the cell is called cytoplasm. But these terms are only valid at certain stages of a cell's life cycle. In the course of cell-division and mitosis, the nuclear envelope disintegrates and the nucleus is replaced by the chromosomes. It makes consequently no sense to speak of caryo- and cytoplasm during these stages.
