Describe the key structures and functions of a eukaryotic and prokaryotic cell. Eukaryotic Cell (1) There are many organelles in the eukaryotic cell micrograph above. Some of these organelles are displayed in the prokaryotic micrograph and so‚ I have described the shared organelles in the prokaryotic micrograph section. Mitochondria The mitochondria cells break down nutrients which then creates energy. They act like a digestive system. This process is called cellular respiration. The

Robert Hooke first looked at a thin slice of cork in 1665; he saw "a lot of little boxes." These little boxes first reminded of the little rooms monks lived in‚ so he called them cells. Hooke observed the same pattern in the stems and roots of carrots and other plants. What Hooke still did not know‚ however‚ was that cells are the basic units of living things. Ten years later‚ the Dutch scientist Anton van Leeuwenhoek focused a microscope on what seemed to be clear pond water and discovered a wondrous

Cells are the basic functional units of all organisms. Cells are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the

ABSTRACT Stem cells have offered much hope by promising to greatly extend the numbers and range of patients who could benefit from transplants‚ and to provide cell replacement therapy to treat debilitating diseases such as diabetes‚ Parkinson ’s and Huntington ’s disease. The issue of stem cell research is politically charged‚ prompting biologists to begin engaging in ethical debates‚ Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation
