REPRODUCTION
GAMETE

5. 5
“The female gamete is called egg cell and
the male gamete is called sperm cell.”
“Gamete contains information. What
information do you think it contains?”
“Yes __________”
“Very Good! It contains the information of
the offspring. This information is what we
call genetic identity.”
“Why do you think gametes are
important?”
“Yes _________”
“Very Good! These gametes unite for
reproduction to happen. What do we call
the union of sperm and egg?”
“Yes __________”
“Thank you! In sexual reproduction, there
are two types of fertilization. Can you
name the two?”
“Yes __________”
“The two types of fertilization are internal
and external fertilization.”
(paste the word)
“Why do you think it is called internal
fertilization? Anyone?”
“Yes _________”
“Very Good! “Internal fertilization, in which
the eggs are retained within the
reproductive tract of the female until after
they have been fertilized by sperm
inserted into the female by the male.”
“The embryo can either develop inside the
female body until it is born alive or develop
(raise their hands)
“The genes of the parents.”
(raise their hands)
“Gametes are important in reproduction
because it is their union that makes new
organism.”
(raise their hands)
“Fertilization”
(raise their hands)
“Internal and external fertilization”
(raise their hands)
“When we say internal fertilization, this
means that the male animal releases
sperm cells into the body of the female
animal to fertilize an egg cell.”
INTERNAL FERTILIZATION
EXTERNAL FERTILIZATION

inside an egg laid by the female until it
hatches. Most land animals undergo
internal fertilization.”
“How about external fertilization?”
“Yes ________”
“Good! In external fertilization, both types
of gametes are shed into water and the
sperm swim or are carried by currents to
the eggs.”
“I have here 5 mystery boxes. Each box
contains an animal or insect. I will give you
a trivia about the animal inside and you will
guess what it is. Do you understand?”

“Very Good! It is dog. What type of
fertilization do you think dogs belong?”
“It is in internal fertilization.”
(raise their hands)
“When we say external fertilization it
happens when a female animal releases
egg into the environment to be fertilized by
the sperm cells also released by a male
animal into the environment.”
(listen attentively)
(raise their hands)
“Dog”
“Dogs undergo internal fertilization.”

“Yes teacher!”
“None teacher!”
