This document discusses plant classification and adaptation. It describes the different types of plants from the smallest that need microscopes to see to the largest trees. It explains the divisions of spermatophytes into gymnosperms and angiosperms, and then further divides angiosperms into monocots and dicots. It also describes plants that do not produce seeds like algae, fungi, bryophytes, and pteridophytes. In addition, it provides examples of plant adaptations and uses of plants for medicine.
2. Plants are living things in different
sizes – from very tiny to very tall
ones. The smallest plant cannot be
seen without using a microscope.
The big ones like Acacia tree, can be
seen even from far afar.
8. Gymnosper
ms
Seed-producing plants that do not have
true flowers
Also known as conifers because they
produce woody cones
Cones are fruits of conifers and are made up
of scale
Are grown to stop the force of the winds
around farms and to decorate parks and
yards
9. Angiosperms
Seed-producing plants that produce
flowers
Garden and wildflowers, weeds, plants
that produce crops and vegetables,
cereal grains, and trees that lose their
leaves in the fall
Most of the trees in the Philippines
Divided into two groups:
monocotyledons or monocots
Dicotyledons or dicots
10. Monocots
Plants that produce seeds with
one seed leaf
Mono means “one” cot means
“seed leaf”
Usually have narrow, smooth
edged, parallel-veined leaves
11.
12. Dicot
s
Plants that produce seeds with
two seed leaves
Di means “two” cot means “seed
leaf”
Usually have broad,
irregularly shaped, netted
leaves
19. Bryophytes
• Simple plants but have more
complicated parts than algae and
the fungi
• Have simple leaves
• Do not have true roots and stems
• Possesses root-like and stem-like
structures
• Have chlorophyll and can produce
own food
Example: moss and liverwort
20. Bryophytes
• Simple plants but have more
complicated parts than algae and
the fungi
• Have simple leaves
• Do not have true roots and stems
• Possesses root-like and stem-like
structures
• Have chlorophyll and can produce
own food
Example: moss and liverwort
21. Pteridophyte
s
•Plants that have true roots,
stems and leaves but do not
have flowers, fruits or seeds
•Have chlorophyll and make
their own food
Example: ferns and club mosses

24. Nemesio L. Mendiola
• Known as the Luther Burband of
the Philippines
• Was born in Angono, Rizal and
studied at the College of
Agriculture of the University of the
Philippines
• Combined the sweetness of
Hawaiian pineapple and native pina
• His work included rust-resistant
coffee, the ambos banana, the
34. Plants are autotrophs; they
are producers
They harness the energy of
the sun in the process called
photosynthesis
Plants uses sunlight, water,
Carbon dioxide, and minerals
from the soil
Photosynthesis
Takes place in the leaves
Air and carbon dioxide enters
the plant through the stomata
Water and minerals enter
35. Photosynthesis
The chloroplasts are where
photosynthesis occurs which
contain chlorophyll
Chlorophyll is the pigment in
the plant that absorbs sunlight
38. Bark of Cinchona tree
• Used for making quinine (a drug
used to treat malaria)
39. Did you know…
• About 3.3 billion people – half of the world's population –
are at risk of malaria
• In 2010, there were about 219
• an estimated 660 000 malaria deaths million malaria cases
53. Seed Dispersal
• Plants have fruits for easy
dispersal
(humans/animals)
• Some have pods that dry
up
• Some are easily carried
by the wind
• Some are carried by
animals
• Some can be carried by
water
