nucleus controls and regulates the cell and performs cell division.
if the nucleus is removed, the cell is not able to perform well and can't divide.
hence the cell dies off after a very short time.
The nucleus, Red and white cells live with out them and they do just fine.
If you want something small, I would go with an iPad. It can do everything a compute does.
Oxygen
No.
without cell living things cannot live
30 to 50 hrs without oxygen
No, the cell would not be able to digest and break down proteins and the cell would not get enough energy to function properly.
They don't (or at least not well or for long) - it is needed for cell divsion/growth.
If see practically, no. Because a cell is a living thing that means it has some input and output for surviving. Even if a cell has enough reserves stored to live for a period of time it would die after that; a cell needs some resource to live.
grass we can always live without grass
No.
No
A cell is important because you could not live without them.
A cell can't live if it doesn't exist... Rephrase the question, maybe?
Yes.
without cell living things cannot live
People can not live without human resources, because food and shelter is a human resource, and if we don't have food and shelter, we will die!
The protoplasm of a cell is the colorless material comprising the living part of a cell, including the cytoplasm, nucleus, and other organelles. Without it the cell will not live.
The cell will never live. its dead on arrival. Ribosomes synthesize proteins. Without protein the cell cannot survive.
The protoplasm of a cell is the medium through which nutrients and energy are transported. Without the protoplasm, a cell would not live for very long.
