Stomach cancer: Gastric cancer is an uncommon form of cancer in the U.S. Adenocarcinoma and lymphoma make up most of the cases of stomach cancer.
Phytoplankton receive energy through photosynthesis. Photosynthesis is the process of making glucose using sunlight. Carbon dioxide, sunlight, and water combine, producing gluâ¦cose sugars that the being can use for energy.  Zooplankton however feed off phytoplankton and decaying matter. They are known as detrivores.
Mitochondria are the powerhouses of the cell because they âburnâ or break the chemical bonds of glucose to release energy to do work in a cell. Remember that this energy originally came from the sun and was stored in chemical bonds by plants during photosynthesis. Glucose and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell. This releases energy for the cell. ATP is the energy-carrying molecule produced by the mitochondria through a series of chemical reactions. The more active a cell (such as a muscle cell), the more mitochondria it will have. The mitochondria are about the size of a bacterial cell and are often peanut-shaped.
