Who Eats Plankton?

Plankton are the diverse organisms present in the ocean as well as freshwater and are too weak to swim against the water current. Phytoplankton are the primary producers of aquatic ecosystems, which are eaten by zooplankton and other aquatic organisms such as small fish and crustaceans. These primary consumers are eaten by large fish, sharks […]

Who Discovered the Chromosome?

The chromosome was first discovered by Walther Flemming. He called the thread-like structure present in the nucleus as chromatin in 1878. Karl Nageli observed the rod shape chromosomes in the plant cell in 1842 and called it transitory cytoblasts, which were later identified as chromosomes.

Who Discovered Ribosomes?

George E. Palade discovered ribosomes in 1955. He identified them as small particles present in the cytoplasm, which often remain associated with endoplasmic reticulum. Ribosomes are involved in the protein synthesis.

Who Discovered Nucleic Acid?

Nucleic acid was discovered by Friedrich Miescher in 1868 and he named it ‘nuclein’ because he isolated it from the nuclei of white blood cells. Nucleic acid (DNA &RNA) is a long chain biomolecule made up of nucleotide monomers. It carries genetic information. Further reading: Cell – The Unit of Life Cell Cycle and Cell […]

Who Discovered Nerve Cell?

Heinrich Wilhelm Waldeyer coined the term ‘neuron’ in 1891 and described it as the basic functional unit of the nervous system. Purkinje cells were the first nerve cells to be identified by Johannes Purkinje.

Who Discovered Hydroponics?

William Frederick Gericke In 1937, William Frederick Gericke is credited for his earliest modern reference to hydroponics. He grew tomato vines about 7.6 metres high in his backyard in a mineral nutrient solution. He started to popularize this idea of growing plants in a solution of water and nutrients rather than soil while working in […]

Who Discovered Glyoxysomes?

Glyoxysomes were discovered by Beevers and Breidenbach. Bill Breidenbach was Beevers’ postdoctoral fellow, he demonstrated that the enzymes for the glyoxylate cycle were found in a separate organelle, which they named as glyoxysomes.
