robert hooke timestamp

robert hooke

in 1665, this british scientist examined a cork and found little structures which he compared to cellulae (parang prison cells)

outer walls of a former plant cell

what were the cells that robert hooke saw in a cork turned out to be?

antonie van leeuwenhoek

found moving protist and sperm, which he collectively termed “animalcules”.

cell theory

developed in the mid-1800’s as a

result of various discoveries about cells, it is one of

the basic principles of biology.

the cell is the basic unit of life

what is the first postulate of the cell theory

all living organisms are composed of cells

what is the second postulate of the cell theory

new cells are created from pre-existing cells

what is the third postulate of the cell theory

matthias jacob schleiden

in 1838, german botanist __ __ __ established that the small compartments in his plant specimens are cells

all living organisms are composed of cells

matthias jacob schleiden and theodore schwann’s discoveries are under which postulate

the cell is the basic unit of life

‣In order that an organism may be

considered living, it must have a cell.

which postulate?

theodore schwann

in 1839, a german zoologist named ___ ___ after doing microscopic studies of animal cells, instituted that all animals are also composed of cells.

1839

when did theodore schwann institute that all animals are also composed of cells

1838

when did matthias jacob schleiden establish that the small compartments in his plant specimens are cells

rudolf virchow

who introduced the third tenet of the cell theory: omnis “cells come from pre-existing cells”

louis pasteur

who proposed the theory of biogenesis

new cells are created from pre-existing cells

rudolf virchow and louis pasteur’s discoveries were under which postulate

1590

Zacharias Janssen invented a primitive

microscope with the help of his father Hans. (year)

1663-1665

robert hooke viewed a thin slice of cork (year)

marcello malpighi and nehemiah grew

in 1665-1676, these two scientists conducted separate investigations on plant cells. they determined the presence organelles within its cells.

hint: mm (kinda sounds like pasta), ng (bible dude who grew up)

1670-1683

Anton van Leeuwenhoek upgraded Janssen's microscope and produced his lens. With this invention, he discovered mobile organelles in many subjects, which he called animalcules. (year)

robert brown

who discovered the nucleus

1831

when did robert brown discover the nucleus

1838

Matthias Schleiden microscopically examine plants

and recognized that plant parts come from cells. (year)

contribution in phytogenesis

in matthias schleiden’s ___________ he proposed

that the different structures of a plant are all composed of

cells

albrecht von roelliker, 1840

when and who stated that sperm and egg

are composed of cells and that all humans are configured

from cells.

(hint: the year is an even number. something like 2, 4, 6, 8, 10. it looks nice. obviously, the first one is 1. then the second and third are somewhat connected, fourth is a 0)

fermentation

a process to kill bacteria

rudolf virchow, 1858

when and who declared, "Omnis cellulae cellula"

which he meant that cells come from pre-existing cells.

With this conclusion, the cell theory was completed.

louis pasteur, 1849

when and who proved that bacteria are able to

multiply and that bacterial cells come from other bacterial

cells.

rudolf virchow

who declared omnis cellulae cellula
