Match the following columns:

Column I (Scientist)	Column II (Invention)
a. Robert Brown	1. Endoplasmic reticulum
b. Benda	2. Mitochondria
c. Dave	3. Lysosome
d. Porter	4. Nucleus

Solution(By Examveda Team)

a. Robert Brown invented Nucleus in 1831, in a talk at the Linnean Society of London. Brown was studying orchids under the microscope when he observed an opaque area, which he called the "areola" or "nucleus", in the cells of the flower's outer layer.
b. Benda invented Mitochondria. Benda first became aware of the existence of hundreds of these tiny bodies in the cytoplasm of eukaryotic cells and assumed that they reinforced the cell structure. Because they tended to form long chains, he coined the name mitochondria ("thread granules").
c. Dave invented Lysosome. He made serendipitous discoveries of two cell organelles, peroxisome, and lysosome, for which he shared the Nobel Prize in Physiology or Medicine in 1974.
d. Porter invented the Endoplasmic reticulum. The endoplasmic reticulum is one of the most intriguing and fascinating organelles. It is found in all eukaryotic cells and performs an amazing number of different functions. The organelle was named by Keith Porter in 1953.
