3. PLANTITO/PLANTITA

9. LEARNING OBJECTIVES
Learn the fundamental concepts related to the study of plants
Understand the scope and importance of botany as a scientific
discipline
Recognize the relationship between plants and climate change
Learn the complexity of plants and describe the difficulty in creating a
singular definition of a plant

10. PLANTS VS GLOBAL WARMING
Global warming
long-term warming of the planet’s overall
temperature
Greenhouse effect
Causes climate change

11. PLANTS VS GLOBAL WARMING
Role of Plants
Absorbs carbon dioxide
Release oxygen into the air
Prevents flooding

13. Botany
Scientific study of plants
How do you define a plant?

14. Do you think algae is a plant?

19. It is difficult to define a plant. It is more
important to develop a familiarity
with plants and understand how they
differ from animals, fungi, algae, and
the like. The differences are presented in
later chapters.

20. Scientific Method

21. Started before the 1400
The process of objectively establishing facts through testing
and experimentation.
Basic process involves making an observation, forming a
hypothesis, making a prediction, conducting an experiment
and finally analyzing the results.

22. Several fundamental tenets were established:
Source of information1.
All accepted information can be derived only
fromcarefully documented and controlled observations or
experiments.
Claims emanating from priests or prophets—or scientists
—cannot be acceptedautomatically

24. Andreas Vesalius
debunked many of the
anatomical theories
proposed by Galen
Vesalius emphasized the
importance of direct
observation

25. Several fundamental tenets were established:
2. Phenomena that can be studied
Only tangible phenomena and objects are studied, such as
heat, plants, minerals, and weather
Anything that cannot be observed cannot be studied.

28. Several fundamental tenets were established:
3. Constancy and universality
Physical forces that control the world are constant through
time and are the same everywhere.
Constancy and universality allow us to plan future
experiments and predict what the outcome should be

30. Several fundamental tenets were established:
4. Basis
Skepticsm
Willingness to consider new evidences

31. The scientific method is essential in botany for
systematically studying and understanding plant
life, ensuring accurate, reproducible results. It
drives advancements in plant science, leading to
practical applications in agriculture, medicine, and
environmental conservation.

36. FIGURE 1-11 (A) A plant produces numerous offspring, many of
which resemble it strongly (B). Mutations may occur that cause,
for instance, leaves to be malformed and poorly shaped for
photosynthesis (C); most or all these mutants die and do not
reproduce. The normal plants continue to reproduce (B) and (D),
but another mutation may occur that causes the leaves to be larger
and more efficient at photosynthesis (E). These may grow and
reproduce so well that they crowd out the original parental types,
and the plant population finally contains only the type with large
leaves (F) and (G).
