He coined the term "CELL" while discussing the structure of cork. He also described flies, feathers and snowflakes, and correctly identified fossils as remnants of once-living things.
Some of his more famous scientific contributions to botany include providing one of the earliest and most detailed descriptions of the NUCLEUS as well as details about cytoplasmic streaming.
Both reached the conclusion that all plants and animals tissures are composed of cells which were fundamentally different in structure. They organized this previous statement on cells into one theory, which states: - Cells are organisms and all organisms consist of one or more cells. - The cell is the basic of structure for all organisms
Was the premiere cytologist of his day, and one of the most influential formulators of the cell theory. He gave his name to structures throughout the body, including the Purkinje cells of the cerebellum.
Remak substantiated the existence of the cell membrane, while proving that at least some cells originated via division from prior cells. Remak, felt that all cells originated by division, and theorized cell division caused the spread of pathological tissue (like tumors).
He pioneered the modern concept of pathological processes by his application of the cell theory to explain the effects of disease in the organs and tissues of the body. He emphasized that diseases arose, not in organs or tissues in general, but primarily in their individual cells. He wrote and published his aphorism omnis cellula e cellula, which means every cell stems from another cell.
Gregor Mendel is known as the father of genetics. He did exstensive reaserch on pea plants and their variations. His work led to the discovery of chromosomes and DNA.
Was one of the most admirable scientists in the field of plant biology, not just as the founder of modern plant cell biology but in addition as an excellent teacher who strongly believed in "education through science." He contributed to plant cell biology by discovering the discrete stages of karyokinesis and cytokinesis in algae and higher plants.
Walther Flemming founded the study of cytogenetics with his careful observations and documentation of cell structure and cell division. Flemming coined the terms chromatin and mitosis, and described the thread-like structures in the cell nucleus that were later named chromosomes.
He coined the term “chromosome” (1888) to describe the bodies in the nucleus of cells and invented a number of embryological terms, including those describing the structure of developing teeth that are still in use.
He discovered that, during fertilization, the nuclei of sperm and egg do not fuse, as previously thought. Rather, each contributes sets of chromosomes in equal numbers. With this study, published in 1890, Boveri provoked great interest in the chromosomes; but his idea that they were central to inheritance frequently met with skepticism.
Cajal's findings were made possible by his masterful use and modifications of the staining technique invented by Camillo Golgi, an Italian physician and scientist. He shared the Nobel Prize in Physiology or Medicine in 1906 with Golgi "in recognition of their work on the structure of the nervous system".
Sutton argued that chromosomes are the mechanism of how traits are passed on from parents to offspring. Furthermore, he supported Gregor Mendel's 1865 theory of independent assortment and segregation of hereditary factors. Sutton argued that each parent passes on a half set of chromosomes to their offspring. Sutton's theories explained the variance in and the combinations of traits in Mendel's works.
