Step-by-step explanation:
In 1888, Liberty H. Bailey established the first horticulture lab in the U.S. at Michigan State University, which is located in East Lansing. This was a significant contribution to the scientific study of plants and their cultivation for educational and research purposes. Horticulture, which encompasses the arts, science, technology, and business of plant cultivation, has flourished thanks to such dedicated research facilities. Botanical gardens, such as those mentioned in historical context, have been instrumental in the research on plants and continue to be so today, with examples found in Sydney, Singapore, and Bogor that date back to the colonization era. As educational institutions focused on practical fields like agriculture, universities have been key in advancing agricultural science.
