Biology: About Mitosis and Proteins
The following example essay on "Biology: About Mitosis and Proteins" condense the complicated data we learned about these specific subjects. The first topic I will discuss is the replication procedure called mitosis. Another sophisticated process that happens in cells is protein synthesis. The cell is absolutely a very sophisticated part of an organism. One instance that exemplifies this argument is that cells can produce protein. It isn‘t as simple as just making protein, and it involves decoding and transcribing DNA…...

Smallest Unit Of Life
The cell is the smallest unit of life. Organism can be made up of one or more cells. In multicellular organism groups of cells can work together to form tissue. Organs are formed from different tissues and work together with other organs in organs systems. The same kind of organism living together in the same area makes up a population. Different population living together in the same area makes up a community. An ecosystem includes a community and the area’s…...

Osmosis & Selective Permeability
Osmosis is the dispersion of water. Our cells are capable of absorbing nutrients because, the cell membrane is selectively permeable (some molecules can effuse freely through the membrane while others cannot). In this experiment we used dialysis bag as a model of the cell membrane. Our hypothesis was that the glucose will diffuse out of the membrane into the beaker filled with iodine solution. To demonstrate dialysis tubing we used water, starch and iodine. When starch and iodine react together…...

Osmosis And Diffusion Lab Report
Kinetic energy, a root of energy stored in cells, causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water likely. Water potential…...

Betacyanin Leakage Through Membranes
Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage By: Trevor Sandum, Lab 2, March 9, 2013 Introduction: A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk, 2013). The membrane is necessary for sustainability of the cell’s life, it separates the cell from the outside environment, and is responsible for diffusion, exocytosis and endocytosis, and transport.Essay Example on Betacyanin Leakage Through Membranes It can…...

The excessive fertilizer caused the soil to turn hypertonic to the plant cell. As a result, water diffused from the plant cells into the soil by osmosis and the plant cells began to shrink. With little or no water left in the corn plant’s cells the plants wilted and…...

Voltaic Cell Experiment Lab Report
Voltaic cell is a device in which a redo reaction spontaneously occurs and produces an electric current. In order for the transfer of electrons in a redo reaction to produce an electric current and be useful, the electrons are made to pass through an external electrically conducting wire instead of being directly transferred between the oxidation and reducing agents. A salt bridge must be used to avoid popularization of the electrodes by facilitating the circulation of ions from electrolyte. Each…...

Agar Cell Diffusion Lab Report
Hypothesis: I expect to find that when the surface area o volume of a cell reaches a certain level, diffusion alone won’t be able to supply the cell materials needed, and as single-celled organisms take in and release substances by means of diffusion across the cell membrane, this process limits cell size. I predict that as the rate of diffusion will be too slow to deliver materials to the center of the cell in the larger cells, it could result…...

Lastly carbohydrate molecules of the membrane are relatively short-chain polysaccharides, which has multiple functions, for example, ell-cell recognition and acting as receptor sites for chemical signals. The plasma membrane is a permeable membrane. An important role of the plasma membrane is to maintain the integrity of the cell, holding the cell contents together. Membrane permeability is a quality of the cell's plasma membrane which allows certain substances to pass while forming a barrier against others, controlling exchanges between the cell…...
