Cell Theory Flashcards
Are the basic building blocks
of all living things.
CELLS
The smallest functional unit within
organisms that are capable of
independent functioning.
CELLS
Also contain the body’s
hereditary material and can make
copies of themselves.
CELLS
List down the general functions of the cells
- Regulation of Internal Environment
- Acquisition ang utilization of Energy
- Responsivenivess to its environment
- Protect and support
An organism’s ability to keep a
constant internal state is called
Homeostatis
It is stored in the bonds present
in food molecules, and it will be
converted by the cells into more
usable forms.
Chemical Energy
A cell must first be able to
determine the changes that have
taken place before deciding on the
necessary responses that will
ultimately result in the
maintenance of normal internal
conditions.
Responsiveness
Disproven theory
that life came from
nonliving matter
Spontaneous Generation Theory
Who disproved the spontaneous
generation theory?
Francesco Redi
Who conducted the Swan Neck Experiment
Louis Pasteur
What experiment did Pasteur conduct
Swan Neck Experiment
The experiment consisted of broth boiled in S-flasks.
Swan Neck Experiment
From what experiment proposed “Cells only arise from pre-existing cells”
Swan Neck experiment
An Italian scientist who first disapproved of the spontaneous generation theory.
Lazzaro Spallanzi
He proved that organisms coming from the air can be killed by boiling.
Lazzaro Spallanzi
He invented the first telescope.
Zacharias Janssen
He observed cork cells under a
compound microscope.
Robert Hooke
He observed microorganisms such as blood cells, yeast cells, sperm cells, and bacteria cells by using his practical microscope.
Anton van Leeuwenhoek
Botanist who proposed all plants are composed of cells.
Matthias Schleiden
German biologist who proposed that all animals are composed of cells
Theodor Schwann
German medical doctor proposed that
all cells come from pre-existing cells.
Rudolf Virchow
He observed in the microscope that cells are dividing
Rudolf Virchow
First principle of cell theory
All living organisms are composed of
one(unicellar) or more cells (multicellular)
Second principle of cell theory
The cell is the basic unit of life and of the
structural organization of an organism
