On our surface, inside and all parts in between, necessary units called cells are constantly keeping your body in a living condition. Robert Hooke is who identified and named cells. “He thought that the small , simple units looked like the bare prison cells. His work launched a new frontier in scientific exploration that led to modern cell theory; all living things are made of cells, cells are the basic units of structure and function in all living things, and all cells come from the reproduction of existing cells.” (Moulton, 2004).

There are two main types of cells: eukaryotic and prokaryotic. An example of eukaryotic cells include animal and plant cells, and fungal cells. Prokaryotic cells include bacteria and archaeans. Plant cells have

There were four concentrations and these were, 0.5M, 1M, 1.5M and 2M plus distilled water and air as the control. When performing this experiment, the main element to consider is hypertonic, hypotonic and isotonic solutions and how they relate to osmosis.

Osmosis is the process where a fluid passes through a semipermeable membrane, which moves from an area which the solute is present in high concentrations. As a result of osmosis, there will be an equal amount of fluid on either side of the barrier, creating an isotonic solution.

When cells are placed in an isotonic solution, the movement of water outside of the cell is exactly balanced by movement of water in the cell. With a hypotonic solution, if concentrations of dissolved solutes are less outside the cell than inside the cell, the concentration of water on the outside is correspondingly bigger. Cells without walls will swell and can possibly burst if excess water is not removed from the cell. Cells with walls often benefit from the turgor pressure that develops in hypotonic environments. With a hypertonic solution, if concentrations of dissolved solutes are greater outside the cell, the concentration of water outside is correspondingly lower. Because of this the water inside the cell will flow out to obtain equilibrium, causing the cell to decrease in size. As the cells lose water, they will lose the ability to function or divide (Pearson Education,

    Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within cells, but water is perhaps the single most important molecule in any living system (Hayden and McNeil 2012). Since water molecules are so small, they are constantly going into and out of the cell. Osmosis is a situation where more water molecules are moving across the membrane in one direction than the other (Hayden and McNeil 2012). During osmosis the net movement of water molecules will be from a solution that has a lower osmotic concentration to a solution that has a higher osmotic concentration. When a solution has a higher concentration of solute within the cell than out, it is called hypertonic. When a solution has a lower concentration of solute within the cell than out, it is called hypotonic. And when there are equal concentrations inside and out of the cell, it is called isotonic. The relative osmotic concentration can be determined by a change in mass of the tissue.…

    7. Humans' cells are in isotonic solution that keeps equal number of solutes both inside and outside of the cell. If the cell is put in a hypotonic solution, water will move into the cell. This causes the cell to burst and die. On the other side, if you put the cell in a hypertonic solution, water will move the outside of…

    Cells must move materials through membranes in order to maintain homeostasis. The cellular environment is aqueous, indicating that the solutes dissolve in the solvent, water. When a cell is hypertonic, or hypotonic, to its surroundings, it tries to make concentration of solution inside and outside itself equal. However, the solutes are too big to pass the cell membranes without the help of channel proteins, or transport proteins. Water may freely pass through the membrane by osmosis, which requires no energy. Thus, the cell starts to take in, or release, water until it is isotionic to its…

    The lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration. Five artificial cells were created, each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic, hypotonic, or isotonic solutions for a period of 90 min. Over time, the rate of osmosis was measured by calculating the weight of each artificial cell on given intervals (every 10 minutes). The resulting weights were recorded and the data was graphed. We then could draw conclusions on the lab.…

    This lab has several key objectives. First, to learn about diffusion and osmosis, and the different factors that affect the rate at which these processes take place. In order for cells to maintain a stable state, they must be able to regulate the particles that move through the cytoplasm, and across its membranes. Diffusion and osmosis are the two physical processes that insure these things take place for the cells to operate smoothly. Second, to gain a better understanding of the role of selectively permeable membranes in osmosis, and to learn about the significance of hypotonic, isotonic, or…

    On the other hand, if the cell is placed in a solution of water that has a higher concentration (of water) compared to the concentration of water inside the cell, then osmosis will cause more water to move into the cell than will move out and this will cause the cell to swell. In this case, we say that the solution of water is “hypotonic”.…

    The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane. (Miller/Levine) Osmosis occurs when there is an area of higher and lower concentration. Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic, hypertonic, and isotonic. When in comparison to another solution, a hypertonic solution has a lower concentration, a hypertonic solution has a higher concentration, and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different concentrations. The hypothesis is that an egg placed in distilled water will gain mass while an egg placed in syrup would lose mass.…

    Because plant cells have rigid cell walls, the cells maintain their shape and size to a large extent in hypotonic and hypertonic solutions. In the hypotonic solution the plant cell’s vacuole fills up with water and pushes the cell’s cytoplasm against the cell’s wall. In the hypertonic solution the cell’s vacuole loses water to the outside of the cell and the cytoplasm shrinks away from the cell wall. Paramecium cells have contractile vacuoles which they use to expel water that moves into the cytoplasm in hypotonic solutions. (Paramecium lives in fresh water, and its normal environment is hypotonic to the inside of the…

    There are three types of environments in which cells are located which include isotonic, hypotonic and hypertonic. In an isotonic environment, the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell, the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of water on the outside of the cell and a high amount of solute inside the cell, water will be drawn inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a hypertonic environment, water will leave the cell, as the amount of water in the cell is higher than that outside of the cell. As a cell looses water in a hypertonic environment it becomes smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth, although some live in slightly hypotonic solutions. (Alonzo, 2008)…

    INTRODUCTION: In order to fully understand the concept of this experiment, one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The progress in which a cell is in its balanced state is called equilibrium. Diffusion is a functioning way for cells to reach their equilibrium. Equilibrium is reached by controlling what enters and exits the cell through a cell membrane that selectively filters molecules by slowing down their movement, allowing them to pass through, or not allowing them to pass through the membrane. Diffusion and osmosis go hand-in-hand. Osmosis is generally the same as diffusion, however, deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab, we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different solutions, we must understand that there are three possible differences in concentrations between a cell and its environment. The terms hypotonic, hypertonic, and isotonic are used in referring to the identification of the possible relative concentrations. The first term, hypotonic, is the solution that contains lower concentrations of solute particles, which means that the concentration inside the cell is greater than the concentration outside. A hypotonic solution causes the cell to swell in size. The second term, hypertonic, is the solution that contains higher concentration of solute…
