Agar, Option 1, is one of the commercial products obtained from Gelidium and Gracilaria. Agar is commonly used in laboratories to grow microbes because of its gel-like consistency. It provides a solid surface for bacterial and fungal cultures to grow on. Apart from its laboratory applications, Agar is also used in the food industry. It is commonly found in ice-creams and jellies as a stabilizing agent. Agar helps give these foods their desired texture and consistency. Chlorella, Option 2, is a type of green algae and is not obtained from Gelidium and Gracilaria. Spirulina, Option 3, is a type of cyanobacteria and is also not obtained from Gelidium and Gracilaria. Gymnosperms, Option 4, are a group of plants that bear naked seeds and are unrelated to Gelidium and Gracilaria.
