THE ORGANELLES OF EUKARYOTIC CELLS . The difference between Prokaryotic and Eukaryotic Cells is organelles‚ membrane enclosed structures that perform specific duties. The most important of all is the “nucleus‚” this holds the DNA and is surrounded by a double membrane. The Prokaryotic lacks a nucleus which is not partitioned from the other cells by membranes. The region between the nucleus and plasma membrane is called cytoplasm and in the Eukaryotic cell it consists of various organelles

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a

are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell injury is hypoxic injury‚ or
