Introductory Message
For the facilitator:
Welcome to the (Subject with Grade Level) Alternative Delivery Mode (ADM)
Module on ( Lesson Title) !
This module was collaborativelydesigned, developed and reviewed by educators both
from public and private institutions to assist you, the teacher or facilitator in helping
the learners meet the standards set by the K to 12 Curriculum while overcoming
their personal, social, and economic constraints in schooling.
This learning resource hopes to engage the learners into guided and independent
learning activities at their own pace and time. Furthermore, this also aims to help
learnersacquire the needed 21st century skillswhile taking into consideration their
needs and circumstances.
In addition to the material in the main text, you will also see this box in the body of
the module:
As a facilitator you are expected to orient the learners on how to use this module.

7. 5
What I Need to Know
This module was designed and written with you in mind. It is here to helpyou master
the nature of Biology. The scope of this module permits it to be used in many different
learning situations. The language used recognizes the diverse vocabulary level of
students. The lessons are arranged to follow the standard sequence of the course.
But the order in which you read them can be changed to correspond with the
textbook you are now using.
The module is divided into three lessons, namely:
 Lesson 1 – Biology: The Science of Life
 Lesson 2 – Biological Concepts as Applied in Technology
 Lesson 3 – Tools Used in the Development of Biology and Biotechnology
After going through this module, you are expected to:
1. identify the unifying ideas in biology;
2. explain the different life processes;
3. explain biological concepts in a given technology;
4. identify the parts and function of the microscope;
5. name special tools used in research and technology; and
6. describe the contributions of Filipino and foreign scientists in the field of
biology and technology

What’s New
Biology Defined
Biology is the science that studies life and living things, including the lawsthat
govern the phenomena of life.
Every aspect of life from the smallest submicroscopic living particle to the largest
and most imposing of plant and animal species is included in the study of biology.
Biological study encompasses all that is known about any plant, animal, microbe
or other living thing of the past or present.
Branches of Biology
The amount of knowledge gained in biology is so large that it has many branches.
The following table lists some of the major ones.
Table 1. Some Branches of Biology
Name Focus
Botany plants
Zoology animals
Anatomy structure of living things
Taxonomy classification of living things
Cytology cells,their structure and functions

What’s More
Activity 1.1 Understanding Science Words
There are two ways you can understand science words better. One way is by
defining the word in context. The way the word is used gives you a clue as to its
meaning.Another way is by looking at the parts that make up the word. Each word
part can give you a clue as to the meaning of the whole word.
Learning the Skill: Defining Words in Context
1. First, read to see if the word is defined directly in the sentence.
2. If the word is not defined directly, read several sentences beyond the one in
which the word first appears. These sentences may provide information
about the definitionof the word.
3. If possible, define the word based on your own past knowledge. You may
have learned the word in an earlier grade, or you may be familiar with it
because you hear it everyday.
4. Figure out the meaning of the word by how it is used in the sentence and by
the sentencesaround it.
Find the definitionsof the italicized words.
1. Biology is the study of life.
2. A cat is a mammal.
3. All living things can reproduce
4. Green plants carry out photosynthesis.

13. 11
What I Have Learned
1. The basic characteristics of living things include movement, metabolism,
growth, response, and reproduction.
2. Metabolism is the sum of all chemical activities essential to life. Ingestion,
digestion,respiration, and excretion are metabolicactivitiesthat occur in all
organisms.
3. Life span is the maximum length of time a particular organism can be
expected to live.
4. A living thing reacts to a stimulus, which is a change in the environment,by
producing a response.
5. Reproduction is the process by which organisms produce offspring.
6. Asexual reproduction requires only one parent while sexual reproduction
requires two parents.
7. Living things need energy for metabolism. The primary source of energy for
all living things is the sun.
8. Oxygen in the air or dissolved in water is used by all organisms during
respiration.
9. Carbon dioxide is used by plants to make food.
10. Homeostasis is the ability of an organism to keep conditions constant inside
its body when the outside environment changes.
