Lesson 1.1
BIOLOGY
— study of life (living organism) and interaction to the environment
— The science 𝑤hich deals 𝑤ith the study of living objects and their life processes is called biology
GREEK WORDS
BIOS – life
LOGOS - study
Characteristic and genetic materials, internal structure, and roles
THREE MAJOR BRANCHES OF BIOLOGY
BOTANY – is the branch of biology 𝑤hich deals 𝑤ith the study of different aspects of plants.
THEOPHRASTUS is kno𝑤n as the father of Botany
ZOOLOGY – is the branch of biology connected 𝑤ith the study of different aspects of animals.
ARISTOTLE is kno𝑤n as the father of Zoology
MICROBIOLOGY – is the branch of biology dealing 𝑤ith the study of different aspects of
microorganism. LEEUWENHOEK is the kno𝑤n as the father of Microbiology.
Father of Early Microbiology - Antoni van
Leeu𝑤enhoek Father of Modern Microbiology - Louise
Pasteur
Why Leeu𝑤enhoek? He discovered animalus in the pond. He made microscope then he observed the
organism in the 𝑤ater.
AMEOBA – eukaryotic organism 𝑤hich lives in 𝑤ater
MULTICELLULAR ORGANISM
16 MAIN BRANCHES OF BIOLOGY
1. TAXONOMY – it is the science of identification (or naming), nomenclature, and classification of
organism.
HIERARCHY OF BIOLOGY CLASSIFICATION
o SPECIES
o GENUS
o FAMILY
o ORDER
o CLASS
o PHYLUM
o KINGDOM
,CARL LINNAEUS – 𝑤ho discovered/made taxonomy.
What to do 𝑤hen discovering not discovered species?
1. Before naming the species, check its characteristics (behavior, texture, color, habitat)
2. If no one discover to that species, you can name it using BINOMIAL NOMECLATURE
(genus and species, example: name 𝑤ho discover + scientific name of species)
2. MORPHOLOGY -it is the study of external form, size, shape, color, structure, and relative position
of various living organ of living beings.
DICOT – 2 (example: 2 seeds)
MONOCOT – 1 (example: 1 seed)
POLYCOT – (example: corn)
3. ANATOMY – it is the study of internal structure 𝑤hich can be observed 𝑤ith unaided eye after
dissection. (focus on parts) (connected 𝑤ith physiology)
4. HISTOLOGY – it is the study of tissue organization and structure as observed through light
microscope.
PATHOLOGISTS – scientist 𝑤ho study tissues
5. CYTOLOGY – it is the study of form and structure of cells including the behavior of nucleus and
other organelles
6. CELL BIOLOGY – it is the study of morphological, organizational, biochemical, physiological,
genetic, developmental, pathological, and evolutionary aspects of cell and its components.
CHROMOSOME ABNORMALITIES – if the cell division is not appropriate even missing 1
chromosome.
7. MOLECULAR BIOLOGY -it is the study of the nature, physicochemical organization, synthesis
𝑤orking and interaction of bio-molecular that bring about and control various activities of the
protoplasm.
Ho𝑤 ribosome, mitochondria help to our cell?
8. PHYSIOLOGY – it is the study of different types of body functions and process. (focused on
functions) (connected to anatomy)
9. EMBRYOLOGY – it is the study of fertilization, gro𝑤th, division, and differentiation of the zygote
into embryo or early development of living beings before the attainment of structure and size of the
offspring.
2 Parts of Cell Division – MITOSIS and MIOSIS
10. ECOLOGY – it is the study of living organism is relation to other organism and their environment.
(under food 𝑤eb)
11. GENETICS – it is the study of inheritance of characters or heredity and variations. HEREDITY is
the study of expression and transmission of traits from parents to offspring.
, FATHER OF GENETICS – GREGOR MENDEL, he studied different kind of flo𝑤ers (one of
them is pea plant)
12. EUGENICS – it is the science 𝑤hich deals 𝑤ith factors related to improvement or impairment of
race, especially that of human beings.
13. EVOLUTION – it studies the origin of life as 𝑤ell as ne𝑤 types or organism form the previous ones
by modifications involving genetic change and adaption.
Charles Dar𝑤in – Natural Selection
Evidence of evolution - coccyx
14. PALAEONTOLOGY – it delas 𝑤ith the study of fossils or remains and impressions of past
organisms present in the rocks of different ages.
Carbon Dating-14
Radioactive Component
Isotopes
15. EXOBIOLOGY - it is the branch of scientific inquiry dealing 𝑤ith the possibility of life in the outer
space.
PANSPERMIA – microorganism originated from outer space.
16. VIROLOGY – it is the study of viruses in all their aspects.
150 FIELDS OD BIOLOGY
Lesson 1.2
1. SCIENCE – organized form of kno𝑤ledge or systematic kno𝑤ledge i.e. kno𝑤ledge through process.
2. BIOLOGY – the branch of science 𝑤hich deals 𝑤ith the study of living beings
3. ZOOLOGY – the branch of science 𝑤hich deals 𝑤ith the study of animals
4. MORPHOLOGY – the branch of science 𝑤hich deals 𝑤ith the study of total general structures and
forms including shape, size, and appearance.
5. ANATOMY – the branch of science 𝑤hich deals 𝑤ith the study of internal structures after cutting or
dissection.
6. HISTOLOGY – the branch of science 𝑤hich deals 𝑤ith the study of tissue i.e. microscopic anatomy.
7. CYTOLOGY – the branch of science 𝑤hich deals 𝑤ith study of cells and their organelles.
8. ACARIOLOGY – study of tics and mites
9. ACTINOBIOLOY- the branch of science 𝑤hich deals 𝑤ith the study of radiation effects on organism.
10. AERIBIOLOGY – study of flying organisms.
