The size depends on the amount of DNA stored in the cell. :)
well, I believe it's because if a cell is too big, it has to feed more. As the surface area increases, so does the volume, remember. So think of a balloon. The surface area is very tiny compared to the volume, correct? So, the cell is so tiny because if it were even , say, the size of a quarter, it would have to feed a WHOLE lot to keep from starvation.... I'm pretty sure that's it. So you see, the DNA keeps the cell from starvation.
The information stored in its DNA is able to meet all of the cell's needs when it is small. An information crisis would occur if a cell grows without limit.
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.
The mitochondria contain their own DNA in plants and animals; and chloroplasts contain their own DNA in plants and other photosynthetic organisms. Both of these structures divide (almost like cells) inside the cells.*This is also evidence for the theory of endosymbiosis, in which early cells ate early prokarotic cells (bacteria) and gained new organelles.
A cell that undergoes mitosis, such as a bacteria cell, splits to create an identical cell (daughter cell) that has identical DNA. So, when a cells split to multiply and grow, there DNA is the same, unless a mutation occurs.

The cells size and shape relate to its function.
Cells are what keeps us alive. they hold our DNA and our DNA is what tells us apart. the cells are protected by the cell wall in plants and cell membrane in animals.
DNA, Diffusion, and Surface Area to Volume Ratio.
DNA is the blueprints of the cell. It will be like trying to write a book without anything to write about. The DNA tells the cell what to do by sending mRNA.
They divide and grow back to their normal size, so there are two cells of the same size with exactly the same DNA.
True.When a cells size increases,it can't transfer enough nutrients throughout the cell if the cell size is big.So it makes copies of its DNA
Prokaryotic and eukaryotic cells are similar in which of the following ways?
The virus's mission is to take over our body cells and use our DNA in the cells to reproduce the virus's own kind,so that it will not go extinct,but it makes us ill too, and after a while our cells die one by one as the DNA is being used to the limit by the virus.
Bacterial cells, animal cells, and plant cells all have DNA. DNA contains information for the cell on how to perform tasks. In plant and animal cells, DNA is contained in a nucleus, unlike bacterial cells where DNA is contained in a nucleoid.Hope this helped
Eukaryotic cells are, on average, ten times the size of prokaryotic cells.Genomic composition and lengthThe DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes.
no. Cells have DNA not the other way around
