a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.

CHAPTER 7 LECTURE SLIDES Respiration • Organisms can be classified based on how they obtain energy: • Autotrophs – Able to produce their own organic molecules through photosynthesis • Heterotrophs – Live on organic compounds produced by other organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions

Nonetheless many people don’t know how dangerous it can be on their bodies. The use of drugs can have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Heart disease can cause chest pain‚ heart attacks‚ heart failure‚ and arrhythmia. Cigarette smoking is related to heart disease because it raises triglycerides‚ damage cells that line the blood vessels‚ and its makes blood clot more often which can block blood flow to the brain and heart. Smoking cigarettes does not only affect the user but also people around them. The smoke the user exhales can be very harmful to others. CDC stated that “Secondhand smoke causes nearly 34‚000 early deaths from coronary

How Cancer Cells Differ From Normal‚ Healthy Cells Cancer cells are very different from healthy cells. Healthy cells grow and divide like they are suppose to‚ whereas cancer cells do not grow and divide in a healthy way. So instead of acting in healthy ways as the body needs to function the cells begin to grow in unhealthy ways and affect all other cells. (http://biology.about.com/od/cellbiology/ss/normal-cells-cancer-cells.htm) There are many things that can happen to us that can cause our healthy

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells
