1. General Biology 2
•This subject is designed to enhance
the understanding of the principles
and concepts in the study of biology,
particularly heredity and variation,
and the diversity of living organisms,
their structure, function, and
evolution

2. CONTENT
Organismal Biology
Genetics
Evolution and Origin of Biodiversity
Systematics Based on Evolutionary
Relationships

3. Content Standard:
o Plant and Animal Organ
Systems and their
Functions
o Feedback Mechanisms
ORGANISMAL
BIOLOGY

4. PERFORMANCE
STANDARD
The learners shall be able to:
develop a presentation (e.G.
Role-playing, dramatization
and other forms of
multimedia) to show how an
organism maintains
homeostasis through the
interaction of the various
organ systems in the body

5. PLANT GROWTHAND
DEVELOPMENT

6. •Plant grow from uptake of
water and nutrients from the
soil, supplied with the heat
energy from sun, and aided
with carbon dioxide.

7. Kangkong makes
a snapping sound
due to the
turgidity of
plant’s cell from
water uptake
Hypertonic, isotonic, and hypotonic effect on
plant cell

8. How Important Is Water To
Plants?

9. •Water is an essential requirement for
plants survival.
•Water uptake allows plants to
metabolically utilize the chemical
compounds and micronutrients obtained
from the surrounding soil.

10. The presence of root
hairs in some plants
increases the urface
area for water
absorption.
Root nodules also
occur in some plants
wherein nitrogen-
fixing bacteria
establish a symbiosis
with plant to
convert nitrogen gas
to ammonia.

11. •The shoot and root system have
developed a specialized function to adapt
to certain environmental condition.
•Ginger (luya) is a specialized stem known
as rhizome.
•Rhizomes serve as storage of stacrch and
protein, which permits perennial growth.

12. •The colorful
specialized leaves of
bougainvillea may be
seen as pink, white,
or yellow shade to
attract pollinators to
the small flower at
the center of this
bracts.

13. •Prop roots are also
specialized plant parts
that we see in
mangrove or bakawan.
•This prop roots
function to anchor and
support the mangrove
on the regularly water-
logged soil.

14. Name other examples of specialized
plant parts.
