Question 3

___________ observed the section of cork by a primitive type of microscope and found that it was made up of small hollow units like honeycomb. He termed the structural unit as a cell.

Answer 3

Robert Hooke (1635 - 1703)
Year: 1665

Question 4

What year does Robert Hooke observed the section of cork by a primitive type of microscope and found that it was made up of small hollow units like honeycomb. He termed the structural unit as a cell?

Answer 4

1665

Question 5

___________ published microscopic anatomy of plants and advanced a theory that the stamen corresponds to male, while pistil corresponds to female reproductive organ.

Answer 5

Nehemiah Grew (1628 - 1711)
Year: 1672

Question 6

What year does Nehemiah Grew (1628-1711) published microscopic anatomy of plants and advanced a theory that the stamen corresponds to male, while pistil corresponds to female reproductive organ?

Answer 6

1672

Question 7

He improved the microscope by the technique of grinding the lens. He reported the studies on free cells such as protozoa and bacteria and thus opened the door to a new world of microorganisms. He also studied blood cells.

Answer 7

Anthony Van Leeuwenhoek (1632 - 1723)
Year: 1674

Question 8

What year does Anthony van Leeuwenhoek (1632-1723) improved the microscope by the technique of grinding the lens. He reported the studies on free cells such as protozoa and bacteria and thus opened the door to a new world of microorganisms. He also studied blood cells?

Answer 8

1674

Question 9

He showed the presence of sex in plants. He demonstrated that in maize, seeds are not produced unless pollen is applied to the pistil. He concluded that pollen is the male element, while pistil is the female element.

Answer 9

Rudolf Jacob Camerarius (1665-1721)
Year: 1694

Question 10

He published the information on his work of plant hybridization. He made hybrids between different varieties of tobacco and between some plant genera. By using reciprocal crosses, he showed the equal contribution of male and female parents to their offspring.

Answer 10

Joseph Gottlieb Kolreuter (1733-1806)
Year: 1761 - 1766

Question 11

He studied plant cells and discovered nucleus in Tradescantia. He described it as a central feature of living cells.

Answer 11

Robert Brown (1773-1858)
YEAR: 1828

Question 12

He described cell division and showed that cells arise through partition walls formed between preexisting cells.

Answer 12

Hugo von Mohl (1805-1872)
Year: 1835

Question 13

They put forth the cell theory on the basis of accumulated experimental results:
○ The cell is the smallest structural element of a multicellular organism and as a unit, it is itself an elementary organism.
○ In a multicellular organism, every cell has a specific function to perform, and represents a working unit.
○ A cell can only be produced from another cell by cell division.

Answer 13

Matthias Jacob Schleiden (1804-1881) and Theodor Schwann (1810-1882)
Year: 1838 - 1839

Question 14

He proposed a theory of evolution known as theory of inheritance of acquired characters:
○ Variation in an individual is brought about by:
■ conscious effort,
■ reaction to environment
■ use and disuse of the organ.
○ Heredity carries forward the changes that are acquired during the lifetime of the individual.
