Eduard Adolf StrasburgerBorn 1 Feb 1844; died 19 May 1912 at age 68.German botanist and plant cytologist who accurately described the embryonic sac in gymnosperms (such as conifers) and angiosperms (flowering plants), along with demonstrating double-fertilization in angiosperms. He recognized that new cell nuclei can only result from the division of other nuclei and showed that the sperm and the egg have half the number of chromosomes found in body cells. He coined the terms cytoplasm for the fluid found in a cell and nucleoplasm (1882) for the fluid found in the nucleus. The upward movement of sap in trees was demonstrated by his research to be physical, rather than a physiological, process.«[DSB and obituary in Botanical Gazette gives date of death as 19 May 1912.
