In a hypotonic solution an animal cell will generate some processes. We know that cells belong to plants and animals. The difference between the animal and plant cells is done by cell wall. Unfortunately, animal has no cell wall. What is the function of cell wall? It has function as the protector of the main cell to retain its shape when outside environment has changed. It makes plant have static movement rather than animals and human. Meanwhile, we have good flexibility because we have no cell walls guys. Because of this reaction against new environment, it brings some solutions and one of them is hypotonic solution.
Before we are going to know in a hypotonic solution an animal cell will, we need to know about plasma membrane. What is plasma membrane? It is a double layers which surrounding all cell. This is not wall cell obviously because the layers come from phospholipids. In other words, plasma membrane is the road of materials which coming inside and outside the cell. For your information, the plasma membrane has special permeable that different with other permeable around the cell. That is why any material such as water can be easily flowing up inside and outside the membrane.
In a hypotonic solution an animal cell will be less of concentrated. This condition will force the water to move inside the cell via membrane. Usually, the water comes from outside or higher place into lower place. This solution won’t be stopped until the concentration is not equal after all. It needs internal pressure to pump out the water from the cell membrane. In simple way, the pressure inside the cell is very low because the water comes from outside the membrane. It means concentration is focused on the outside cell. Do you understand know what will happen of hypotonic solution, right? Let us read other solutions which related with hypotonic solution.
If cell has less concentration inside, the hypertonic solution is the vice versa. It will happen when the concentration is focused inside the cell membrane. In this process, the water inside the cell will be flowing out into outside and coming the solution. You need to notice that the concentration could be different with the inside cell concentration. In this case, the animal faces ocean or fresh water. So, the water which flow out from the membrane is not inside the cell any longer. Thus, in a hypotonic solution an animal cell will have less concentration.
