This document discusses several topics related to botany and biology. It provides definitions of key terms like taxonomy, classification, biodiversity, and discusses subfields of botany like applied botany. It also contains passages from the Quran in Arabic. The document touches on classification of living things, characteristics of living things, diversity of life, and discusses both special creation and evolution theories.

9. Diversity of life
Special creation - supernatural or divine force
created the universe, its contents and all life forms.
1. Based on faith = a firm belief in something for which
there is no proof.
2. Based on the theory of evolution = life originated, and
evolution proceeds, by random chance.
3. You must accept either evolution or religion, but not
both.

13. History of Plant Taxonomy
Taxonomy is probably the oldest science and certainly almost
from the beginning of human existence plants have been classified
based on their edibility, and other uses to humans.
The development of plant taxonomy has at least five distinct periods:
Preliterate: since this is pre written record, we have little direct
knowledge of this period.
* The Egyptians knew wheat, olive trees, grapevines and fig trees.
Also, they produced paper out of the pith of papyrus (Cyperus
papyrus).
* However, through the years, all cultures have learned which of
the plants around them are useful, whether for medicines, food,
clothing, shelter, weapons, etc.
14. II Ancient literate
The development of writing.
Western taxonomy starts in ancient Greece.
Aristotle: (384 BC – 322 BC)
was a Greek philosopher, a
student of Plato and teacher of
Alexander the Great. He wrote on
many subjects, including physics,
metaphysics, poetry, theater,
music, logic, rhetoric, politics,
government, ethics, biology and
zoology.
15. Theophrastus (370-285) BC,
Greek who studied under Plato
and Aristotle and considered
grandfather of botany.
1. He wrote more than 200 works only a few of
which survived. The most important were:
Enquiry Into Plants, and The Causes of
Plants.
2. Was a friend of Alexander the Great who had a botanical interest and
who sent him plants from his travels.
3. Wrote about 500 species of plants and described cotton, pepper,
cinnamon, bananas and named many modern genera including
Asparagus and Narcissus.
16. Among his most significant observations are:
1. distinctions between external (organs) vs. internal (tissue) structures.
2. distinction between different kinds of tissues.
3. classification into trees, shrubs, subshrubs and herbs.
4. distinction between flowering vs. non-flowering plants.
5. recognition of different kinds of sexual & asexual reproduction.
6. understood basic anatomy, e.g. sepals & petals modified leaves.
7. true understanding of fruits.
17. Pedanius Dioscorides (1st century A.D.)
A Roman military surgeon, added
about 100 additional species from the
Mediterranean flora and some
illustrations to produce a similar
document, Materia Medica, that
described the plants and their medicinal
applications. This included natural
groupings of species that represent well-
defined modern Families (Fabaceae,
Apiaceae, Lamiaceae).
This five book study (Materia Medica )
became the most central pharmacological
work in Europe and the Middle East for
the next sixteen centuries.
18. The Islamic Golden Age or Islamic Renaissance
= Medieval or dark ages in Europe
During the Muslim conquests of the 7th and early 8th centuries,
Rashidun armies established the Islamic Empire, which was one
of the ten largest empires in history.
During this period the Muslim world became the unrivalled
intellectual centre for science, philosophy, medicine and education
as the Abbasids championed the cause of knowledge and
established the "House of Wisdom" (Arabic:الحكمة )بيت in
Baghdad; where both Muslim and non-Muslim scholars sought to
translate and gather all the world's knowledge into Arabic. Many
classic works of antiquity that would otherwise have been
forgotten were translated into Arabic and later in turn translated
into Turkish, Persian, Hebrew and Latin.
19. Jabir Ibn Haiyan (721-815 C.E.)
He had established himself as one
of the leading scientist while he
practiced medicine and alchemy
in Kufa (in present day Iraq).
He introduced experimental
investigation into alchemy
(derived from Arabic word al-
Kimiya), creating the momentum
for the modern chemistry.
He and other Arab chemists were able to extract different
anesthetic compounds from local herbs for local or general
anesthetization.
20. Ābu anīfah Ā mad ibnḤ ḥ
Dawūd Dīnawarī (828–896C.E.)
Al-Dinawari is considered the
founder of Arabic botany for his
Kitab al-Nabat (Book of Plants),
which consisted of six volumes. Only
the third and fifth volumes have
survived, though the sixth volume has
partly been reconstructed based on
citations from later works. In the
surviving portions of his works, 637
plants are described from the letters
sin to ya. He also discusses plant
evolution from its birth to its death,
describing the phases of plant growth
and the production of flowers and
fruit.
21. Avicenna (Hussain ibn
Abdullah ibn Hassan ibn Ali
ibn Sina).
(born c. 980 near Bukhara,
contemporary Uzbekistan,
died 1037 in Hamedan in
modern Iran) was a polymath
and the foremost physician
and philosopher of his time.
He was also an astronomer,
chemist, geologist, logician,
paleontologist, mathematician,
physicist, poet, psychologist,
scientist, and teacher.
22. About 100 treatises were ascribed to Ibn Sina. Some of them are
tracts of a few pages, others are works extending through
several volumes. The best-known amongst them, and that to
which Ibn Sina owed his European reputation, is his 14-volume
The Canon of Medicine, which was a standard medical text in
Europe and the Islamic world up until the 18th century.

Dhiya al-Din Abu Muhammad Abdallah Ibn AhmadDhiya al-Din Abu Muhammad Abdallah Ibn Ahmad
Ibn al-Baitar al-Malaqi (1197- 1248)Ibn al-Baitar al-Malaqi (1197- 1248)
He learned botany from the Málagan botanist Ibn-i-Rumia (Abu al-Abbas
al-Nabati) with whom he started collecting plants in and around Spain. Al-
Nabati was responsible for developing an early scientific method,
introducing empirical and experimental techniques in the testing,
description and identification of numerous materia medica, and
separating unverified reports from those supported by actual tests and
observations. Such an approach was thus adopted by Ibn al-Baitar.
24. In 1219, Ibn al-Baitar left Málaga to travel in the Islamic world to collect
plants. He travelled from the northern coast of Africa as far as Anatolia.
After 1224, he entered the service of al-Kamil, an Ayyubid Sultan, and
was appointed chief herbalist. In 1227 al-Kamil extended his domination
to Damascus, and Ibn al-Baitar accompanied him there which provided
him an opportunity to collect plants in Syria. His researches on plants
extended over a vast area including Arabia and Palestine. He died in
Damascus in 1248.
Ibn al-Baitar’s major contribution is Kitab al-Jami fi al-Adwiya al-
Mufrada, which is considered one of the greatest botanical compilations
in history, and was a botanical authority for centuries. It was also a
pharmacopoeia (pharmaceutical encyclopedia) and contains details on at
least listing 1,400 plants, foods, and drugs, 300 of which were his own
original discoveries. His work was translated into Latin in 1758 and was
being used in Europe up until the early 19th century. The book also
contains references to 150 other previous Arabic authors as well as 20
previous Greek authors.
25. Ibn Al-Baitar’s second major work is
Kitab al-Mlughni fi al-Adwiya al-Mufrada
which is an encyclopedia of Islamic
medicine, which incorporates his
knowledge of plants extensively for the
treatment of various ailments, including
diseases related to the head, ear, eye, etc.
In cancer therapy, Ibn al-Baitar
discovered the earliest known herbal
treatment for cancer: "Hindiba", a
herbal drug which he identified as
having "anticancer" properties and
which could also treat other tumors and
neoplastic disorders. After recognizing
its usefulness in treating neoplastic
disorders, Hindiba was patented in 1997
by Nil Sari, Hanzade Dogan, and John
K. Snyder.

27. Abu Abdallah Muhammad Ibn Muhammad Ibn
Abdallah Ibn Idris al-Qurtubi al-Hasani, was born in
Ceuta, Spain, in 1099 C.E.
Idrisi wrote on botany, geography, fauna, zoology and therapeutical
aspects. His work was soon translated into Latin and, especially, his books
on geography remained popular both in the East and the West for several
centuries.
His major contribution lies in medicinal plants as presented in his several
books, specially Kitab al-Jami-li-Sifat Ashtat al-Nabatat. He studied and
reviewed all the literature on the subject of medicinal plants and formed
the opinion that very little original material had been added to this
branch of knowledge since the early Greek work. He, therefore, collected
plants and data not reported earlier and added this to the subject of
botany, with special reference to medicinal plants. Thus, a large number
of new drugs plants together with their evaluation became available to the
medical practitioners. He has given the names of the drugs in six
languages: Syriac, Greek, Persian, Hindi, Latin and Berber.
28. Renaissance:
Started ca. 14th century in Italy.
A) Two major technological innovations contributed to renaissance and
especially to plant taxonomy:
1. Printing press: Which made knowledge available to all and botanical-
medical books called herbals became popular.
2. Science of navigation: Navigation started the age of exploration and
almost immediately the number of known plants increased
dramatically. New systems of classification were needed to handle this
increase.
B) Basically four distinct periods to this era:
1. Herbalists - (1500's) motivated by practical considerations, i.e. medical
and agricultural uses of plants. No real systems of classification but
marked period of original work rather than copying the ancients work.
These books were based on first hand observations by the authors and
provided detailed and accurate description of the plants of medicinal
use.
29. 2. 17th century - Large numbers of new plants from
voyages necessitated better systems of classification.
Caspar Bauhin (1560-1624)
(Swiss) Wrote Pinax which was a register of
plants know to science at that time. He also
included other names for the plants, i.e.
SYNONYMY. Also generally credited with
modern concept of genera and species. He also
experimented with BINOMIAL system of
naming plants.
Andrea Cesalpino (1603-1519) (Italian) tried
to base classification on logic rather than
utilitarian concepts (such as medicinal uses).
He realized that some features are more
meaningful than others in classification, a
priori reasoning (today emphasis on floral
features).
30. John Ray (1626-1705)
British naturalist divided plants into
nonflowering and flowering types, and
flowering plants into dicots and monocots.
Carolus Linnaeus (1778-1707)
Linnaeus, a Swedish physician, is considered
the father of plant taxonomy and one of his
works, Species Plantarum (1753) is the
starting point for modern taxonomy.
He realized that some characters were more
useful than others and he developed a Sexual
System of classification which was based on
3. Linnaean period - 18th century. By end of
17th century there were too many new plants
to deal with and plants were referred to by
descriptive Latin phrases.
31. the numbers of reproductive parts. Purely artificial but allowed one
to easily identify an unknown plant by keying it out much as we do
today. He described 100's of species, all binomials that have a L.
after them. His most significant contribution was the consistent use
of the binomial system in which each species was referred to by only
two names, the genus and specific epithet.
Abu Ali al-Hasan ibn al-Hasan ibn al-
Haytham (965-1040 C.E.)
An Egyptian polymath (born in Iraq) whose
research in geometry and optics was
influential into the 17th century; he was the
first person to test hypotheses with verifiable
experiments, developing the scientific
method more than 200 years
before European scholars learned of it—by
reading his books.
32. He made a thorough examination of the passage of light
through various media and discovered the laws of refraction.
He also carried out the first experiments on the dispersion of
light into its constituent colours. His book Kitab-al-Manadhir
was translated into Latin in the Middle Ages, as also his book
dealing with the colours of sunset.
First record of using glass lens for magnification was by him.
He is the first to describe accurately the various parts of the eye
and give a scientific explanation of the process of vision.
He is known for the earliest use of the camera obscura.
He contradicted Ptolemy's and Euclid's theory of vision that
objects are seen by rays of light emanating from the eyes;
according to him the rays originate in the object of vision and
not in the eye.
Through these extensive researches on optics, he has been
considered as the father of modern Optics.
33. Antonie van LeeuwenhoekAntonie van Leeuwenhoek
(1632—1723)(1632—1723)
Dutch microscopist, whoseDutch microscopist, whose
simple, single lens microscope
(glass bead in metal holder)

accurate description ofaccurate description of three
shapes of bacterial cells.
Robert HookeRobert Hooke
(1635-1703(1635-1703))
he described his microscopic
observations of plant tissues
and coined the term cell.
34. Nehemiah Grew (1641 - 1712)
Botanist and physician uses the microscope to
give a thorough description of plants in The
Anatomy of Vegetables.
Wilhelm Friedrich Benedikt Hofmeister (1824 to
1877)
German biologist and botanist. He is widely
credited with discovery of alternation of
generations as a general principle in plant life. His
proposal that alteration between haploid and
diploid phases constituted a unifying theory of
plant evolution that was published in 1851, eight
years before Darwin's (On the origin of species).
35. Eichler, August Wilhelm 1839–1887
German botanist that modified former systems
to reflect a better relationship between plants.
The plant kingdom was divided into non-floral
plants (Cryptogamae) and floral plants
(Phanerogamae) by him.
Eichler system was the foundation for Adolf Engler's System and it
had large acceptance worldwide (mainly in Europe).
Eichler System is the first one in which the concept of Evolution was
accepted and therefore it was also the first one to be considered
phylogenetic. Moreover Eichler was the first taxonomist to separate
Phanerogamae in Angiosperms and Gymnosperms and the former
in Monocotyledonae and Dicotyledonae.

1892-1987
Louis Victor, duc de Broglie hypothesized in 1924 the theory of wave
nature of electrons.
Ernst Ruska discovered the principle of electron microscopy when
he established that electron beams can be focused like light in a lens.
In 1931, together with Bodo von Borries and Max Knoll at the
Technical University in Berlin, he built the first microscope that
functioned according to this principle. In 1939 Ruska and von
Borries developed a marketable electron microscope in the Siemens
Laboratory for Electron Optics and Electron Microscopy.
