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.
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.
Growth hormones primarily signal for cells to grow larger and divide, which can result in overall tissue growth. They do not directly cause cells to shrink or decrease in size.
Many celled organisms grow by increasing the number and size of their cells through cell division and cell growth. This involves processes like mitosis, where cells replicate and divide to form new cells, and cellular growth, where cells accumulate more cytoplasm and organelles to increase in size. Additionally, the organism may also accumulate more cells through processes like cell proliferation or cell differentiation.
Yes, cells in the G1 phase of the cell cycle grow in size as they prepare for DNA synthesis. This growth is necessary to ensure that newly replicated cells have enough organelles and resources to support two daughter cells.
Yes, growth occurs when cells divide and increase in number, leading to an increase in overall size of the organism. This process is controlled by a combination of genetics, hormones, and environmental factors.
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.
because if they got any bigger then you possibly could explode.
Cellular division is the cellular equivalent of reproduction. It is how cells reproduce.
If get to larger then the nutrients cant pass through
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.
Smaller cells work more efficiently because their "supply lines" are short.
They grow twice the size, then divide into two.

mitosis of body cells
Cells in an embryo grow no larger than a certain size before they divide because as the cell grows, its surface area to volume ratio decreases. This leads to difficulties in nutrient exchange and waste removal, hindering the cell's ability to function properly. Dividing into smaller cells helps maintain an optimal surface area to volume ratio for efficient cellular processes.
They divide and grow back to their normal size, so there are two cells of the same size with exactly the same DNA.
