A egg cell is 60-70 micro meters long(2) millimeters
The size of a chicken egg cell may vary from one egg to another. It is estimated that a single cell of the chicken is about 100 micron.
It varies, but I'd assume anywhere from 1-75 micrometers.
An ovum is about 100 microns (or micrometers) in diameter.
A human egg cell is 100 micron in size.
How many millimeters wide is an human egg cell?
I doubt that there is any limit to how large a cell can be. However, the cell's size really depends on the function of the cell. Generally, in the case of a single-celled microorganisms, the cells have to move materials (example, nutrients and wastes) across the cell membrane to stay alive. If the materials move in or out of the cell too slowly, for example the waste accumulates in the cell or the cell is unable to get its nutrients quickly, the cell will die. In order for the rate of diffusion of materials across the cell membrane be as efficient as possible, the cell has to increase its area of cell membrane per unit volume, which is to say, be as small as possible. As for the current largest cell, which is the ostrich egg, the function of the egg is NOT moving materials in and out of the cell surface membrane, but to protect the chick inside the egg and to contain the nutrients that will nourish the chick inside until the chick hatches. The chick needs a lot of nutrients and the chick is going to grow a lot in the egg, so the egg (cell) has to be rather large. There is also an organism known as caulerpa, which is a meter long single-celled organism, but I have no idea why is it that huge.
The process when an egg cell and a sperm cell COMBINE is called Fertilization
Osmosis occurs in an egg cell if you place it in liquids. If you put it in vinegar, the egg's shell will start to dissolve. Then, you can test osmosis in water or salt water. Because the egg is considered a cell, it will swell the egg cell with plain water (meaning it will increase the egg's mass). With salt water, the egg cell will shrink in mass.
The function of an egg cell is to join with a sperm cell to create a new being after the parents.

Around the same size as a human egg cell.
Like an egg.
The EGG OF AN OSTRICH is the biggest cell in the world.
The egg cell is 85,000 times bigger than the sperm
The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.
Of coarse cell sizes differ. Take and egg for example; it is 100 times the size of an average skin cell
The largest cell- MUCH larger than any other cell- is the unfertilized human egg cell. It is about the size of a period.
the smallest egg cell is fish egg cell
An egg cell is a gamete, and so is a sperm cell.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
The largest single cell in nature is an ostrich egg; it weighs 1.5kg.
A cell is small because small is a lot! Cells are not always the same size. Cell sizes vary for different cell types in the same species. A chicken egg that we eat is a cell.
