Question
_______ is essential for the survival of cell.
- Water
- Salt
- Flagella
- Nucleus
Hint:
- Cellular survival depends on an organism's ability to respond and adapt to the extracellular signals in its environment.
The correct answer is: Nucleus
- Cellular survival depends on an organism's ability to respond and adapt to extracellular signals in its environment.
- To survive, every cell must have a constant supply of vital substances such as sugar, minerals, water and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.
- Without water, cell membranes would lack structure, and without proper membrane structure, cells would be unable to keep important molecules inside the cell and harmful molecules outside the cell, so water is essential for the survival of cell.
