A hypertonic solution was added to it and it leads to the cell shrinking.
Hypertonic means the solution has a lower water potential than the cell, and because of osmosis, water molecules will flow from a region of higher water potential to a region of lower water potential, through the semi permeable membrane, which is the cell membrane. Therefore, the water will flow away from the cell. This process is caused by natural tendency. The cell lose so much water that the cell shrink.
Note that only animal cells shrink if put in hypertonic solution, plant cell does not since it has a cell wall. In plant cells, cell membrane will detach from the cell wall and plasmolysis occurs.
We can use the word RINGER to memorize the characteristic of living things.
Respiration - the ability to breathe and respire.
Irritability - the ability to detect and react to stimulus
Nutrition - taking in nutrients (eg. Food) for energy to growth, repair etc
Growth - the permanent increase in size and mass
Excretion - to get rid of toxic, waste or excess materials
Reproduction - to make more of that organism.
In addition, there is also movement, which is an action which causes a change in place or position.
Only the organisms with these characteristics are categorized as living things.
Cell growth occurs in interphase.
The cell cycle is composed of interphase, mitosis, and cytokinesis. It can be described in five steps.
The first three steps of the cell cycle are called the interphase. This is where the cell grows, the cell matures, and where the cell carries out its life function. The fourth step is mitosis and the fifth step is cytokinesis.
The interphase has three stages. These are Gap 1, synthesis, and Gap 2.
Gap 1 or growth 1 - where the cell grows and functions normally. Cell growth is twice its original size.
Synthesis - where cell duplicates its DNA
Gap 2 or growth 2 - where cell resumes its growth in preparation for division.
Oxygen lol have a good day
