- Phototroph. Definition. noun, plural: phototrophs. An organism, typically a plant, obtaining energy from sunlight as its source of energy to convert inorganic materials into organic materials for use in cellular functions such as biosynthesis and respiration.upplement. In order to capture light as source of energy, photoautotrophs carry out photosynthesis, converting energy from sunlight, carbon dioxide and water into organic materials. Photoautotrophs provide nutrition for many forms of life. They include the plants, algae and certain bacteria.

atrophy Atrophy. Definition: Decrease in the size of cells, tissues, or organs. Causes of atrophy include poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, disuse or lack of exercise, or disease intrinsic to the tissue itself.Hormonal and nerve inputs that maintain an organ or body part are referred to as trophic.Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level. It can be part of normal body development and homeostatic processes, or as a result of disease.ormonal and nerve inputs that maintain an organ or body part are referred to as trophic.

- Reticulocyte count. An increased reticulocyte count represents increased RBC production and is a criterion for hemolysis but is not specific for hemolysis. In addition to hemolysis, increased reticulocytes may be a response to blood loss or the treatment of iron, vitamin B-12, or folate deficiencies.
