Why can't a cell be as big as a house?

Answer 1

A cell has to be able to maintain homeostasis. The cells surface area to volume ratio has to be maintained. If a cell gets too big, it will not be able to take in enough nutrients and remove metabolic waste in order for it to keep up with the increasing volume. The volume of the cell gets too big and without being able to maintain a balance or ( homeostasis), a cell may in turn die.

Answer 2

Cells have a limited size due to the need for efficient exchange of nutrients and waste products across the cell membrane. Large cells would struggle to maintain these processes effectively. Additionally, a large cell would require a disproportionately larger nucleus in order to control cellular activities, which would be inefficient.

Answer 3

Think of it, if you have one cell as a size of a house what would you want to do with it.

Lets say our (humans) cell is that big, and we got a scar, eventually you'll end.

Answer 4

If a cell gets too large, the process of diffusion no longer works. A cell that is too large can not absorb needed nutrients.
