introduction to life science
biology - is the study of life
bios - life
logos - study
branches of biology
taxonomy
naming & classifying organisms
cytology
cells & animal cells
embryology
formation and development of organisms
anatomy
structures & body parts
physiology
functions of organisms and its parts
biochemistry
biological composition
genetics
heredity & variation
evolution
origin of organisms
ecology
relationship of organisms with the environment
biological levels of organization:
I. atom
fundamental unit of matter
II. molecule
group of atoms
combination of two or more elements
III. cell organelles
centrosome
cell wall
mitochondria
ribosomes
chloroplast
cytoplasm
IV. cell
basic unit of life
V. tissue
group of cells
four types
connective
muscle
nervous
epithelial
VI. organ
collection of tissue
what makes the body work
VII. organ system
system of organs
collection of organs
nervous, circulatory, respiratory, reproductive, integumentary, digestive, endocrine, urinary/excretory, lymphatic system
VIII. organism
capable of reproduction
IX. population
group of same species living in the same area
X. biocenoses/community
a community
relationship of organisms
XI. ecosystem
environment of organisms’
interactions of living things with their environment
XII. biome
XIII. biosphere
theories of the origin of life
si malakas, at si maganda
adam and eve in filipino context
first man and woman in the philippine folklore
divine theory of creation
creationism - divine power
god created earth in 6 days
basis is the bible
theory of evolution
charles darwin
biogenesis vs. abiogenesis
biogenesis
making new living things
reproduction
life comes from life
abiogenesis
life comes from non-living things
spontaneous generation
scientists
john needham
theory of spontaneous generation
experiment: flask and broth
if the flask is heated, it will kill all the microorganisms living in that broth
after heating he covered it with a cork and let it sit for a few days
after his observation, he saw microorganisms in the broth
flaw: he didn’t heat the broth enough for it to boil
conclusion: microorganisms spontaneously generated from non-living matter of the broth
francesco redi
experiment: jar and meat
used 3 setups
setup a
unsealed; maggots were seen in here
setup b
sealed, no maggots were seen in here
setup c
covered with gauze; maggots were seen on top of the gauze
conclusion: maggots were offsprings of flies and there is a presence of air
maggots originated from flies which is and existing life form
maggots - larvae of flies
louis pasteur
created the first 3 vaccines
other scientists who contributed in evolution
charles darwin
theory of evolution
proposed that species change over time
survival of the fittest
george-louis buffon
species change as they migrate to new environment
jean baptiste lamarck
species change gradually to adapt to its needs
theory of use & disuse
theory of inheritance
how do we distinguish a living organism?
characteristics of life
growth and development
increases
reproduction
process of making the next generation
sexual
asexual
binary fission
fragmentation
regeneration
homeostasis
balances your body temperature
metabolism
breakdown/gathering of energy
catabolism
breaking molecules to obtain energy
anabolism
process of synthesizing compounds
motility
ability to respond
to move or exhibit spontaneous motion
