As cells get bigger, the components (used to be called organelles but I guess that's changed) get further from the cell walls or membranes. Given the limitations of transport mechanisms within cells, their ability to interact with the cell exterior would eventually be limited to such an extent that the cell would no longer be viable (volume:area). This logic would suggest that cells that do not require much interaction could be comparatively big e.g. some plant and animal structural cells or human eggs (not sure where ostrich eggs fit - are they uni or multi Why_can't_single_cells_grow_very_largestructures?). But, this logic is based on a vision of a cell as a sphere and, by elongating, flattening or other deviation from the sphere, cells can grow larger whilst maintaining effective interaction with the cell exterior e.g. nerve and skin cells.

Hormones are secreted by endocrine glands and are chemical substances which control growth and metabolic activities.

Explain why cells can only grow to a limited size?
Cells will only grow to a certain size. If a cell gets too big, it is much harder for the cell to transport food and wastes in and out of the cell fro the nucleus. so, to avoid this, the cell divides.
Why cant certain cells like bacteria get to be the of an animal like a dog?
Why can't certain cells,like bacteria,get to be the size of a small fish
Growth hormones can make cells grow larger or smaller?
Cells have a correct size, they do not grow bigger or smaller. Growth hormone causes the development of new cells. You get more cells, rather than bigger cells.
What increases in order for a many celled organisms to grow?
The numbers of cells must grow if the organism is to increased in size.
Do cells grow in size during the g1 phase?
The G2 phase is the third phase of the cell cycle. The cells do not stop growing in the G2 phase. In fact, during this period the cells grow rapidly to prepare for cell division.
Why do all cells divide?
Cells are limited by size. They cannot grow beyond a certain extent. This is why the cells multiply to form the various organs of the body.
Why do cells grow to a certain size?
because if they got any bigger then you possibly could explode.
Why is it advantages for a cell to grow only to a certain size and then divide into two smaller cells?
Cellular division is the cellular equivalent of reproduction. It is how cells reproduce.

Why do the cells in an embryo grow no larger than a certain size before they divide?
If get to larger then the nutrients cant pass through
Why is it advantageous for a cell to grow only to a certain size and then divide into two smaller cells?
Smaller cells work more efficiently because their "supply lines" are short.
Do your Cells grow as you grow?
yes, cells grow to an enlarged size and divide into two small cells (which each enlarge and divide as well). but the larger cells get, the more difficult it is for them to function and operate, so they remain within certain size boundaries, getting large enough to divide and halving, large enough to divide and halving.
Why do cells in an embryo grow no larger than a certain size before they divide?
because if they get too large than the nutrients cant pass through it
What do animal cells do to create new cells?
They grow twice the size, then divide into two.
Why cant certain cells like bacteria get to be the of an animal like a dog?
Why can't certain cells,like bacteria,get to be the size of a small fish
How do organisms grow?
Organisms grow by cell division or mitosis which causes increase in number of cells , and then by increase in size of cell .

Cells have a correct size, they do not grow bigger or smaller. Growth hormone causes the development of new cells. You get more cells, rather than bigger cells.
