What Are Some Differences Between Plant & Animal Cells?

Though there are some similarities especially in structural elements, plant and animal cells do differ especially in functions. Animal and plant cells both have cytoplasm, cell membrane and a nucleus. The cell walls of plants are made up of cellulose. Cellulose allows high pressure to build up...

What Is Cell Differentiation?

Cell differentiation is the development of a generic cell into a cell with a specific function, which is directed by various triggers. This differentiation is essential for the renewal of cells and for embryonic development, and occurs numerous times in the development of a single-celled zygote to...

What Is Stem Cell Research?

Every cell in the human body contains the all the genetic material necessary to grow, from conception to death. Newly created cells, which have not yet developed enough to specialize, are called stem cells. Stem cells are cells that may still develop into any kind of body cell. There is great...

What Is a Memory Cell?

Memory cell is a type of cell that belongs to the immune system. There are two types of memory cells, the memory T cells and the memory B cells. Memory T cells triggers the immune system and attacks disease causing bacteria and viruses. Memory B cells make antibodies which kills bacteria and viruses....

What Is Cell Division?

Cells go through the cell division process to divide themselves depending upon the body’s requirements regarding the functions of those particular cells. Cell division is simply the nucleus of the cell splitting, followed by the replication of DNA. There are two categories of cell division based...

Stem Cell Breakthrough Grows New Arteries

A stem cell breakthrough grows new arteries. Scientists studied veins left over from surgery, extracted stem cells from the veins, and discovered material vital for restoring hope for patients suffering from heart disease. Scientists then simulated the growth of new arteries and may have discovered...

What Is a Stem Cell Culture?

A stem cell culture involves removing stem cells from a source material and growing them under laboratory conditions. This area of human research and science is still under ethical debate. Stem cells have the unique ability to grow into any type of cell and have been very useful for various medical...

Researchers Blame Cell Phones for Decline in Bee Populations

Researchers blame cell phones for decline in bee populations.  A group of scientists from the British Bee Association have noticed a sharp decline in bee populations in the United Kingdom.  As of 2009, bee populations dropped by 17 percent in the United Kingdom and nearly 30 percent within...

What Is a Cell Phone Jammer?

A cell phone jammer is an instrument that produces a signal that is within the same frequency range that cell phones use. The competing signals will result in blocking off the transmission of the cell phone because of the interference. Any person who attempts to use a cell phone that is within the...

What Is the Stem Cell Debate?

The stem cell debate centers around religious, political, scientific and ethical controversial opinions and research. The research and extraction of stem cells is controversial despite the obvious end benefits. Scientific research has shown that stem cells can repair damaged human body parts and...
