What are the optimal conditions for cells to survive in water?
Different types of water
Will have different concentrations of minerals
Will affect the cell's absorption and diffusion process
Cleanliness of water
Less organism and bacteria will be find if the water is clean
Has the ability to protect the cells from being destroyed by water
Different types of water have different
chemical compositions and properties
Tap Water
Salt Water
Distilled Water
pH value of water
If pH level of the extracellular fluid
around the cells becomes too acidic
It can disrupt the normal functioning of cellular process
ex. Enzyme activity, protein structure, membrane function
Can affect the ability of cells to generate energy
An increase in pH can affect ion balance and protein function
If the pH level is outside the optimal range for an extended period
Leads to cell damage, cell death
Maintain the pH level within the optimal range is essential
The lower pH value, the more acidic the water is
Most ideal pH range for most cells is 7.38 and 7.87
Deviations from this range can have different effects on cell
(Depending on the servility and duration of the change)
Water temperature
Most cells have a preferred temperature
range in which they can function optimally
Aquatic cells
Temperature range usually between 20-30°C
High temperature
A slightly increased of temperature
can give more energy to the cell
If the temperature is too high
it might experience death or damage
Low temperature
Slightly decreased of temperature
can give less energy to the cell
Ice formation
Cells may be exposed to
the formation of ice crystals
Can damage cellular structure
Cause cell death
Oxygen levels
Cellular respiration
Cells use oxygen in the
process of cellular respiration
If the oxygen level is low, it may not have
enough energy to let the cell function properly
Can lead to cell damage / death
Anaerobic respiration
Cells carry out anaerobic respiration in some cases
Does not require oxygen
This process is much less
efficient then aerobic respiration
Cells may not be able to produce enough
energy to carry out their normal functions
Hypoxia
When oxygen level is low
Hypoxia may occur to cells
Lack of sufficient oxygen
to meet cellular demands
May lead to cellular function decrease
Can lead to cell death
