M1: Cell Theory Flashcards
First compound microscope was invented by ________ ________ (1595)
Zacharias Janssen
published Micrographia containing drawings of cork (1665)
Robert Hooke
observed organisms in drops of water through a simple microscope (1674)
Anton Van Leeuwenhoek
concluded that all plants are composed of cells (1838)
matthias schleiden
concluded that all animals are composed of cells (1839)
theoder schwann
proposed that cells came from another existing cells, completing the cell theory (1855)
rudolf virchow
was the first scientist to use the word “cells” in 1665. Hooke
used it to describe the small chambers within a cork that he observed under
a microscope. The microscope was of his own design.
Robert Hooke
Hooke observed that the thin sections of the cork resembled “_______-_____”
or small “Boxes or bladders of air”. He noted that each cell was distinct from
the others. At that time, he was not aware that the cork cells were just long
dead cells that lacked internal structures.
honey-comb
was a German botanist who made an extensive
microscopic observation of plants and described them as being composed of
the cells. He postulated or hypothesized that every living thing is made up of
cells or the product of the cells.
Matthias Schleiden
also believed that cells formed through crystallization, rather than
cell division.
Matthias Schleiden
was a German physiologist who made microscopic
observations of animal tissue.
Theodor Schwann
_________ (study of cells)
cytology
In 1839, after a conversation between Schleiden and Schwann, _________
realized that there are similarities existed between their observations of
plant and animal tissues. This led to the concept that cells are essential
components of plants and animals.
schwann
was a pathologist who published an editorial essay entitled
“Cellular Pathology”, which popularized the concept of the Cell Theory.
Rudolph Virchow
The
essay used the Latin phrase omnis cellula a cellula, which means _____________________.
all cells arise from cells
was also known as the Father of Pathology.
Rudolph Virchow
He was the first to
determine the causes of various diseases by examining their effects to
tissues and organs.
Rudolph Virchow
The Cell Theory
- ____living organisms are made up of one or more cells.
- The cell is the basic structural and functional _____ of life.
- Cells arise from ____-existing cells.
- all
- unit
- pre
There are also living organisms that are made
up of more than one cell called ____________ or multi-celled organisms.
multicellular
There are living organisms that are made up of one cell called
_______ or single celled organisms.
unicellular
MODERN POSTULATES
- cells carry ________ material which is passe from one cell to cell during cell division
genetic
MODERN POSTULATES
- all cells are basically the _____ structure and __________ composition
__%-__% water = cell
- same, chemical
70% - 75%
study of living things and their vital processes and includes non living things
biology
biochemical processes
biology
MODERN POSTULATES
- Energy flow (__________ processes) occurs ______ cells
- biochemical, within
-using chemical to produce sugar
- done by bacteria that doesn’t get sunlight
chemosynthesis
has a very large vacoule
plant cell
has a nucleus
eukaryote
basic membrance bound unit that contain the fundamental molecules of life and of which all living things are composed
cells
observed the living cells (1673)
anton van leeuwenhoek
observed the remains of dead plant cells (1665)
robert hooke
all plants are composed of cells (1838)
matthies schleiden
stated that all animals are made of cells (1839)
theodor schwann
reasoned that cells come only from other cells (1855)
rudolf virchow
described cork as consisting of “geart many little boxes”. These boxes reminded him of ________ or _____ that monks lived in
cubicles or cells
complexity of life
a____ > m________ > O__________ > C____ > Ti______ > Org____ > or____ S______ > Or______ > Po_______ > C____________ > Ec_________ > B___________
atom > molecules > organelle > Cell > tissue > Organ > Organ system > Organism > Population > COmmunity > Ecosystem > Biosphere
basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.
cell
In 1590, the Janssen Bothers, Dutch eyeglass maker , invented the very first
microscope
it is an instrument used to magnify small objects.
microscope
In 1665, While looking at a piece of cork under the microscope, Robert Hooke saw a box-shaped structures that he called
cell
it is the most basic unit of life.
cell
In 1674, _______________________, while looking at pond water under the microscope, he observed what he called “ animalcules”.
Anton van Leeuwenhoek
He is known as the father of microbiology
Anton van Leeuwenhoek
In 1838, Mathias Schleiden, a German botanist stated that ____________are made up of cells.
Plants
In 1839 Theodore Schwann, a German physiologist concluded that ___________are also made up of cells.
Animals
In 1855, Rudolf Virchow stated that cells come from preexisting cells through
cell division
It is a process by which a parent cell divide into two or more daughter cells.
cell division
HOW CELL WAS DISCOVERED
When R_______ discovered they were able to make glass in the 1st century BC.
Romans
