(26 cards)
The study of living organisms and their life processes
*Biology
The use of biological systems or organisms to develop
products or technologies, often for medical, agricultural, or environmental
applications.
*Biotechnology
The study of genes, heredity, and the variation of organisms
*Genetics
The study of the relationships between organisms and their
environment
*Ecology
The study of microscopic organisms such as bacteria,
viruses, and fungi
*Microbiology
The study of the chemical processes within living
organisms.
*Biochemistry
The study of drugs and their effects on living organisms
*Pharmacology
is the study of life, which is applied in different fields.
Biology
is a group of advanced biology. —— is also called biological Science. It is a rapidly advancing and
thoroughly inspiring discipline of studies
Life Science
Life of Earth began more than 3.8 billion years ago evolving from the most basic of microbes into an array of complexity over time.
CONCEPT OF LIFE
All living things are of made up cells. Someorganisms are unicellular and some are multicellular
CONCEPT OF LIFE
ORGANISMS CONSIST OF ONLY SINGLE CELL THAT CARRIES OUT PROCESSESS. Ex. Bacteria, amoeba, Paramecium
UNICELLULAR
Organism are composed of many cells which perform
specialized and specific function
MULTICELLULAR
The Process of evolution to explain how life developed.
According to him, there was growth from simple to complex
form
Charles Darwin
Many people believed that everything in the world was created by a supreme, It
emphasizes the some of all creation is God and with Him, nothing is impossible
SPECIAL CREATION
THEORY
During the ancient times, people used only their naked eyes to
see things. They believed that life originated as a spontaneous event. It is a hypothetical process by which living organisms developed from nonliving matter, also the ARCHAIC THEORY that utilized this process to
explain the origin of life.
SPONTANEOUS/ABIOGENESIS GENERATION THEORY
an Italian Scientist
* He demonstrate that maggots do not just appear spontaneously but produced from the eggs of flies.
FRANCESCO REDI (1626-
1697)
- A French chemist and
microbiologist. - He disprove the theory of
spontaneous theory
LOUIS PASTEUR (1822-
1895)
were introduced through the dust particles, and that these microorganisms did not arise from the broth itself.
Microorganisms
who articulated
“Omne vivum ex vivo’
(“Life only comes from life”)
LOUIS PASTEUR
states that life produces that each
animal and plant produced its own kind.
Biogenetic/ Biogenesis Theory
. This is a phrase made
by ———-, a German biologist and philosopher which means
that the development of an organism (ontogeny) expresses all the
intermediate forms of its ancestors throughout evolution
(phylogeny
“Ontogeny recapitulates phylogeny” by Ernst Haeckel
- Some evidence indicates that, around 3 billion years ago, Earth’s oceans were covered with ice. This ice may have been hundreds if meters thick, mainly due to the sun being less fierce than it I nowadays. This theory contends that the ice may have protected the compounds, allowing them to interact and, thereby,
creating life.
BENEATH THE ICE
This is the proposal that life on earth from rocks other debris from impact, in the form of highly resistant spores (cosmozoa) such us meteorite
❑PANSPERMIA (COSMOZOIC THEORY
