Because there is water in the cell. Water would form crystals as it freezes. These crystals interrupt the membranes and other organelles in the cells. They look okay while frozen, but once thawed, the cells cannot maintain their integrity any more. There are certain animal, I think a type of frog, that can handle freezing and thawing.
What else can I help you with?
Can you freeze yourself solid and live?
No, freezing yourself solid would lead to irreversible damage to your cells and tissues, resulting in death. The formation of ice crystals within your body would cause severe damage to cells and disrupt bodily functions, making it impossible to survive in a frozen state.
Why might freezing the thymus alter the ability to see nuclear material in the cells?
Freezing the thymus can lead to the formation of ice crystals within the cells, causing mechanical disruption and potential damage to cellular structures like the nucleus. This can affect the integrity of the nuclear material and make it difficult to observe under a microscope. Additionally, freezing can alter the molecular composition of the cells, making nuclear material less accessible for visualization techniques.
Does freezing affect seed germination?
Freezing can damage seed tissues and reduce viability, affecting the germination process. Ice crystals can form inside the cells and disrupt membranes, leading to cell death. It is generally recommended to store seeds in cool, dry conditions above freezing temperatures to maintain their viability.
How does glycerol protect bacteria from freeze damage?
Glycerol acts as a cryoprotectant by reducing ice crystal formation within bacterial cells during freezing. This helps to prevent damage to the cell membrane and other cellular structures. Glycerol also helps to maintain cell volume and integrity during the freezing and thawing process.
Does freezing increase or does it decrease?
Freezing typically decreases the kinetic energy of molecules, causing them to move less and become more stable in a solid state. This process reduces the temperature of the substance, preserving its structure and preventing chemical reactions. In terms of biological materials, freezing can help prevent spoilage and maintain quality. However, it can also cause physical damage to cells if ice crystals form within them.
The impact of freezing temperatures on living cells?
Freezing causes the water inside living cells to form sharp crystals. These crystals puncture and destroy the cellular organelles and membrane. Certain animals have 'cryoprotectants' that help reduce the damage caused by freezing.
What is freezing and how does it affect plants?
Freezing is the process in which water turns into ice due to low temperatures. When plants are exposed to freezing temperatures, the water inside their cells can freeze, causing the cells to expand and potentially burst. This can damage the plant's tissues and lead to wilting, browning, and ultimately death of the plant.
Can you freeze yourself solid and live?
No, freezing yourself solid would lead to irreversible damage to your cells and tissues, resulting in death. The formation of ice crystals within your body would cause severe damage to cells and disrupt bodily functions, making it impossible to survive in a frozen state.
What is meant by chemical freezing cells?
Chemical freezing cells refers to a process in which specific chemicals, often cryoprotectants, are used to prevent the formation of ice crystals during the freezing of biological cells. This technique helps preserve the integrity and viability of cells, tissues, or organs by minimizing damage that can occur due to ice crystal formation. Common cryoprotectants include dimethyl sulfoxide (DMSO) and glycerol, which lower the freezing point and stabilize cellular structures during the freezing and thawing processes. This method is widely used in biobanking and regenerative medicine.

Would freezing yourself save you from cancer?
it just postpone it.because the Cancer cells can't work.
What would happen if glucagon was damaged or missing?
Could not get any Sugers to the cells which means the cells would die off if it was damage.
Does freezing yourself for another time really work?
No. Freezing destroys the cells.
How does equilibration affect cryopreservation?
Equilibration is an important step in cryopreservation as it allows the cells or tissues to adjust to the cryoprotectant solution before freezing. This process helps to minimize osmotic stress and damage to the cells during freezing and thawing. Proper equilibration can improve cell survival rates and maintain cell functionality after cryopreservation.
Can cells be perserved by freezing?
Freezing and thawing can destroy the cells, and this is not a processed used to preserve them. They can be preserved by cryopreservation by lowering the temperature to -196F.
Can a hamster survive being frozen?
No, a hamster cannot survive being frozen. Freezing temperatures can cause irreversible damage to the hamster's cells and organs, leading to death.
