Join the class at least 5 minutes before the time.
Always mute your microphone and avoid doing
unnecessary chats to avoid class disturbance.
Click the ‘Raise Hand’ button if you want to ask something
from your teacher.
Be Polite.
ALWAYS FOLLOW!
Identify the difference between Asexual and Sexual
reproduction.
Differentiate the different types of asexual and sexual
reproduction of an organism.
Give the importance of understanding how reproduction in
different organism works.
OBJECTIVES
INSTRUCTION:
Watch a short video presentation about the topic.
Take down notes of the important points from the video so
you can participate the class discussion and activity.
Make sure to answer your teacher’s questions for the
additional points.
LET’S START
1. What is reproduction?
2. What are the two types of reproduction?
3. Give examples of asexual reproduction.
4. Give examples of sexual reproduction.
GUIDE QUESTIONS
What is
REPRODUCTION?
It is the process by which
living organisms like humans,
animals, plants, and other
organisms form new
individuals of the same kind.
What are the 2 types
of REPRODUCTION?
Asexual Reproduction
Sexual Reproduction
Is the process by which a single
organism produces genetically
identical offspring.
Is the formation of offspring from
the fusion of gametes (egg & sperm
cell) called Fertilization.
Asexual Reproduction
Fission: Asexual
Reproduction
It occurs in prokaryotic
microorganisms and in some
invertebrate, and multi-celled
organisms.
After the DNA molecule replicates, an
organism splits into two separate
organisms.
Organisms like the amoeba, bacteria,
euglena, etc., exhibit binary fission.
Budding: Asexual
Reproduction
Budding occurs when a new organism
starts growing from the parent’s body.
This bud later develops into a mature
organism. It may stay attached to the
parent’s body or break off.
Some examples are hydra, yeast, and
corals.
Fragmentation:
Asexual Reproduction
 Fragmentation is when the body of an organism
breaks into several parts.
 Fragmentation is also known as splitting.
 Each fragment will develop into a mature clone
genetically and morphologically identical to its
parent.
 The organisms that will reproduce through this
process have a specific organs or zones to break
off easily.
 Some examples are the planaria, starfish, and
hydra.
Parthenogenesis:
Asexual
Reproduction
 Parthenogenesis is a natural form of asexual reproduction in
which growth and development of embryos occur without
fertilization by sperm.
 In animals, parthenogenesis means development of an embryo
from an unfertilized egg cell.
Spore Formation:
Asexual
Reproduction
 Spores are formed by fungi
and are often contained
within a structure known as
a sporangium which
disintegrate releasing the
spores into the
environment,
Vegetative Reproduction:
Asexual Reproduction
 Vegetative reproduction is a form of asexual
reproduction found in plants where new
independent individuals are formed without the
production of seeds or spores.
Sexual Reproduction
What are the 2 types of SEXUAL
REPRODUCTION?
Internal Fertilization
External Fertilization
SEXUAL REPRODUCTION IN PLANTS
The vegetative part of a
flower consists of the
following:
 Petals: This is a bright-
coloured part that attracts
bees, insects, and birds.
 Sepals: Sepal is the green-
coloured part beneath the
petals to protect rising
buds.
Stamen: This is the male reproductive organ. It consists of two parts
namely: anther and filaments.
 The anther is a yellowish, sac-like structure, involved in producing
and storing the pollens.
 The filament is a slender, threadlike object, which functions by
supporting the anther.
Pistil: This is the innermost part and the female reproductive organ
of a flower which comprises three parts -stigma, style and ovary. This
is collectively known as the pistil.
 Stigma: It is the topmost part or receptive tip of carpels in the
gynoecium of a flower.
 Style: It is the long tube-like slender stalk that connects stigma
and the ovary.
 Ovary: It is the ductless reproductive gland that holds a lot of
ovules. It is the part of the plant where the seed formation takes
place.
