Human egg or ovum is about the size of this period .
Ostrich egg about the size of a soft-ball.
Both are single cells but eggs are specialized in that they have the nutrients necessary to begin cell division and make a new organism contained within (once fertilized). Technically the egg is really different parts - the white and the yolk are nutrient sacs and are not necessarily part of the cell. Normal cells can't get that big since they have to get materials in and out.
Although they are still quite small, human egg cells are the only cells that are visible by the naked eye. To see other human cells, one would have to use a microscope or other magnification device. :)
About 100 micrometers- or the diameter of a human hair. Very large for a cell.
The human egg cell is 100 microns...whatever that means. It is visible to the human eye and is the biggest cell in the body by volume.
An ovum is about 100 microns (or micrometers) in diameter.

The size of a typical bacterial cell is 0.5-5.0 micrometers, a average human cell is 10 micrometers.
In a cell there is a part that has a specific job (nucleus=control center) just like a human (brain=controlls actions of body) __________________________________________________________________ Actually you cant say they are similar but humans are made of cells, trillions of them, and the type of cell is eukaryotic so we are eukaryotes and eukaryote is a type and there is only one other type known and that is the prokaryote which was the first cell.
Compared to plant cells, they do not have cell walls nor chloroplasts.
No. plants, bacteria, fungi and aerchia all have cells walls though. all cells have a cell membrane, but animal cells (including human cells) have only cell membrane, not a cell wall.
46 - same as every other human cell
Human nerve cells are eukaryotic cells, just like every other human cell.
The size of a typical bacterial cell is 0.5-5.0 micrometers, a average human cell is 10 micrometers.
Human cells also include human nerve cell. The connections are from the nerve cell to the other cells by way of extensions called dendrites.
Any cell that is dividing has a replicated DNA. The highest N:C ratio (nucleus to cytoplasm) is found in malignant neoplasia (cancer) cells. -MWB

All other cells in the human body are the only type that are prokaryotic, meaning that they do not contain a nucleus, the control center of the cell.
White blood cells, red blood cells, and other cell phones.
Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
No - no animal cells have cell walls - only plant cells do.
The Longest cell in the human body is the nerve cell.
Yes, a prokaryotic cell has ribosomes but they are lesser in size compared to other ribosomes.
Single-celled organisms divide into two new cells
