Student’s Activity
1. Activity
The teacher ask the students to answer the
activity entitled “Fix me and You will know
Me”.
- I have here a two sets of puzzled
pictures you need to arrange. The
class will be divided into two. Row

be the Group 2.
- I will only give you 5 minutes to
arrange the puzzled picture.
▪ The students
activity
Pictures used:
Puzzled picture No. 1
Puzzled picture No. 2
2. Analysis
The teacher will discuss, reinforce or defy Expected answers from the student:
the answers of the students in the given
activity.

Based on your activity what can you
say about the picture that you have
puzzled?

Ma’am, the picture shows a
starfish.

The picture shows a family,
ma’am.

Can you tell the difference between
the two pictures?

The picture of the starfish
looks exactly the same with
each other while on the picture
of the family they don’t look
exactly the same with each
other.

What have you observe on the
number of parent depicted on the
picture?


The starfish only have one
parent.
The children have two parents.
Do you have any idea why the
children have two parents while the
starfish only have one?

No, Ma’am.

Don’t worry class because we will going to
elaborate it more as we go along with our
lesson for today.
3. Abstraction
Expected answers from the students:
Now let’s go to our lesson proper.

Do you have any idea what
reproduction is?


To reproduce.
To make an offspring.

No ma’am.
That’s right students.
Reproduction - is the process by
which living organisms like
humans, animals, and plants form a
new individuals of the same kind.

Did you know that there are two
types of reproduction?
There are two types of reproduction
and this are the asexual and sexual
reproduction.

Is there anyone who has idea what
asexual and sexual reproduction is?

None ma’am.
ASEXUAL REPRODUCTION- is
the creation of a new organism from
a single or one parent and does not
involve the combination of gametes
or sex cells. Thus, the offspring look
exactly the same as to the parent.

In your previous activity, what
picture
depicts
asexual
reproduction?

The picture of a starfish
ma’am.

Okay that is correct. Why do you say
so?

Because the starfish only
require one parent to reproduce
and the offspring of the starfish
looks exactly the same to the
parent.

That’s right! Very good. Did you
also know that asexual reproduction
has six different types? These are the
following.
1. Spore formation- organisms
reproduced by forming spores.

Do you have any idea what Expected answers from the students:
 Molds ma’am.
organisms reproduce through spore
formation?
 Mushrooms ma’am.
 Ferns ma’am.
2. Budding- new organism is formed
from an outgrowth called bud from
the parent.


In your own understanding, how can
you describe budding?
When an outgrowth of an
organism matures it separates
from its parent organism and
becomes a new individual of
organism.
3. Fission- organism grows and
duplicates its genetic material then
divides into two.

Do you have any idea what
organisms
reproduce
through
fission?


Bacteria ma’am.
Sea anemones

When the body of an organism
fragmented into different
pieces it grows and develops to
become a new organism of
offspring.

Starfish ma’am.
4. Fragmentation- happens when
new organism grows from a
fragment of the parent.

Who can further explain the concept
of fragmentation?
5. Regeneration- occurs when a
body part is detached from the
parent. This part grows and develops
into a completely new individual.

What is the best example of
organism that reproduce through
regeneration?
6. Vegetative Propagation- it is a
method wherein new plants are
obtained from the parts of old plants
like stems, roots, and leaves without
the use of any reproductive parts.

Can you think of a plant that you can
see in your surroundings that
reproduce
through
vegetative
propagation? How does it work?

A malunggay tree ma’am.
When you cut out the stem of a
malunggqay tree and you plant
it, it grows and becomes a new
plant of malunggay. It doesn’t
require any reproductive parts
to grow.

Do you understand class what
asexual reproduction is?

Yes ma’am.

Very good! Let’s proceed to sexual
reproduction. Is there anyone who
has idea about sexual reproduction?

None ma’am.
SEXUAL REPRODUCTION- is the
type of reproduction that involves
two parents and combination of
gametes (sex cells) to produce a new
organism. Thus, the offspring
produced sexually doesn’t look
exactly the same as the parents
because the offspring’s traits and
genetic makeup is a combination of
its parents.

In your previous activity what image
depicts sexual reproduction?

The image of the family
ma’am.

Wow that is right! Why do you say
so?

Because the family requires
two parents to reproduce and
the offspring in sexual
reproduction doesn’t look
exactly the same as to their
parent.

Precisely! On point answer
students! Did you also know that
sexual reproduction has three
different types? These are the
following.

None ma’am.
1. Conjugation- a bridge forms
between two cells lying side by side
where contents of one cell pass into
the other cell and then combine to
form a zygote which later on
becomes an individual.

Do you have any idea what
organisms
reproduce
through
conjugation?
2. Pollination- combines the male
and female gametes of a flower and
it happens when a pollen grain of the
right kind lands on the stigma of the
pistil.

In your own understanding what is
pollination?

Pollination is the act or
process of transfer of pollen
grains from the male anther of
the flower to the female
stigma.


Human ma’am.
Animals ma’am.
3. Fertilization- a type of sexual
reproduction that combines a male
and female gametes of an organism
to form a zygote.

What are the example of organisms
that reproduce through fertilization?

Do you understand now the asexual
and sexual reproduction?

Yes ma’am!

Now that you have learned about
asexual and sexual reproduction, do
you think that asexual and sexual
reproduction is important in the
ecosystem?

Yes ma’am, it is very
important in our ecosystem.
Expected answers from the students:

Why do you say so? Can you cite at
least three importance of asexual
and sexual reproduction in the
ecosystem?


Asexual
and
sexual
reproduction is important in
the ecosystem because it
ensures the survival of the
species of living organisms.
Asexual
and
sexual
reproduction is important
because it helps in sustaining
life of all living things. For
example, if there is no
reproduction of plants human
would die because there will be
no presence of oxygen.

What will happen if there is no
means of asexual and sexual
reproduction in our ecosystem?

How can you describe the
contribution of each living organism
in the ecosystem?

The process of asexual and
sexual
reproduction
is
important because it ensures
that a specie of organism will
not disappear.

Without asexual and sexual
reproduction there would be no
perpetuation of life and species
would not continue to live on.

Each living organism play an
important
role
in
the
ecosystem. Humans cannot
live without plants that
supplies oxygen and as a
return, plants also need carbon
dioxide from human. Some
animals cannot live without the
welfare of humans and humans
eat animals to survive. Thus, it
is really important to sustain
the life of every organism in
the ecosystem.

activity.
4. Application




The teacher instruct the students to
answer the activity entitled
“Compare and Contrast: Asexual
and Sexual Reproduction”.
I will give you a picture of 10 types
of organisms and what you have to
do is to guess whether the organism
requires one or two parents to
reproduce
Write your answer on the activity
sheet provided and answer the
following guide questions.
I will give you 10 minutes to work
on your activity.
Activity 1: Compare and Contrast:
Asexual and Sexual Reproduction
I. Objectives
1. differentiate asexual reproduction
from sexual reproduction
2. identify the offspring produced
asexually and sexually
3. distinguish the parents involved
in asexual and sexual reproduction
II. Materials
Activity Sheet
III. Procedure
1.
Differentiate
asexual
reproduction
from
sexual
reproduction in terms of factors,
parents involved and the traits of
offspring.
2. Use the venn diagram as shown
below. Place the similarities at the
center and the differences at the
opposite circles of the diagram.
3. Answer the following guide
questions comprehensively.
IV. Data and Observation
ASEXUAL
SEXUAL
]Expected answers from the students:
Guide Questions:
1. Describe the differences between asexual
and sexual reproduction in terms of;
a. number of individuals
_________________________
a. In asexual reproduction it only
involved- requires one parent to reproduce. On
the other hand, in terms of sexual
reproduction it requires two parents to
reproduce.
b. similarities of offspring to parents- b. In asexual reproduction the
_________________________
offspring looks exactly the same to its
parent while in sexual reproduction the
offspring traits are combination of its
parents thus it doesn’t look exactly the
same as to the parents.
2. Do you think both asexual and sexual 
reproduction are important to the
ecosystem?
Support
your
answer.
________________________________
Yes, because if there is no means
of reproduction there would be no
perpetuation of life and the specie
of organisms will not continue to
live on and it will disappear.
C. After the lesson
Teacher’s Activity
1. Generalization
Student’s Activity
Teacher will briefly generalize the
discussions while questioning some of
the students.
1. What is reproduction?

Reproduction is the process by
which living organisms like
humans, animals, and plants form
a new individuals of the same
kind.
2. What are the two classification of
reproduction?

The two kinds of reproduction are
asexual reproduction and sexual
reproduction.
3. How can you differentiate asexual
reproduction
from
sexual
reproduction in terms of parents
involved?

In terms of asexual reproduction it
requires only one parent to
produce an offspring. On the
other hand, sexual reproduction
requires two parents—a male and
female, to reproduce.

Offspring’s
from
asexual
reproduction looks the same with
the parent organism while
offspring’s
from
sexual
reproduction get traits from both
parents.

Yes it is important because if
there is no means of reproduction
individuals of a species would not
exist anymore and the species will
die. Through asexual and sexual
reproduction, new organisms are
produced and the species live on.
4. How can you differentiate the
offspring reproduced asexually and
sexually?
4. Do you think that asexual and
sexual reproduction is important in
the ecosystem? Why or why not?
