1. What will happen if cell’s plasma membrane suddenly encounters a cold environment?
2. What if the lysosome ignored its functions? what would happen to the cell?
3. Is it possible for a cell to have a two nucleus? Why?
4. What will happen if DNA is stored in the wrong place? Does the cell continue to reproduce? Why?

Answer:
1. The cell will try to maintain internal homeostasis by increasing metabolism and generating heat to counter the effects of the cold environment. If the cold environment persists, the cell may go into hibernation or die.
2. If the lysosome ignored its functions, the cell would accumulate waste products and cellular debris, which would eventually lead to the death of the cell.
3. Normally, a cell has only one nucleus, but there are some exceptions. Some types of cells, such as muscle cells and certain types of plant cells, can have multiple nuclei. This happens when the cell needs to divide into smaller cells, and each cell needs its own nucleus and organelles.
4. If DNA is stored in the wrong place, the cell would not be able to properly function, and it would ultimately lead to cell death. If critical genetic information is stored in the wrong place, the cell may not be able to reproduce, leading to a variety of genetic issues and diseases.
Answer:
1. The plasma membrane is the outer layer of the cell and plays a crucial role in the maintenance of cell homeostasis. If the membrane is exposed to cold temperatures, it may cause damage to the cellular compartments and functions, leading to cell death.
2. The lysosomes are organelles responsible for the degradation and recycling of various molecules within the cell. If the lysosomes malfunction and ignore their functions, this could lead to the accumulation of undigested material in the cell, leading to cellular dysfunction and possibly even death.
3. Having two nuclei is possible, known as diploid. In this case, each nucleus would contain a complete set of chromosomes. This happens when a fertilized egg undergoes division into two cells, which then fuse back together, resulting in a cell with two nuclei.
4. If DNA is stored in the wrong place, the cell will not be able to properly reproduce and divide and will ultimately undergo apoptosis (cell death). This is because the DNA contains the genetic information necessary for the cell to carry out its functions and maintain homeostasis. If the DNA is not properly stored or is damaged, the cell will not be able to read and copy the genetic information, leading to cellular dysfunction and death.
