General Information – Biology MCQ

1. Who was the first scientist to use an instrumental for biological studies in 1665?
A. Robert Hooke
B Schwann
C Schleiden
D Virschaw

Explanation: Robert Hooke FRS (28 July [O.S. 18 July] 1635 – 3 March 1703) was an English natural philosopher, architect and polymath. His adult life comprised three distinct periods: as a scientific inquirer lacking money; achieving great wealth and standing through his reputation for hard work and scrupulous honesty following the great fire of 1666, but eventually becoming ill and party to jealous intellectual disputes. These issues may have contributed to his relative historical obscurity

2. The two German scientists who proposed the Cell Theory were
A Mendal and Darwin
B. Theodor schwann and Mattias Schleiden
C Virchow and Purkinje
D Porter and Palade

Explanation: In biology, cell theory is a scientific theory that describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1838. This is usually credited to Matthias Schleiden and Theodor Schwann.
