CLASS RULES
You are here to learn;
make the most of your time.
Raise your hand for
clarifications, questions, and
concerns.
Keep your gadgets.

Matchy-Matchy!
Identify the animals in the picture then match the
adult to their young.

OBJECTIVES
At the end of the lesson the students can:
1. describe the different ways of how plants and
animals reproduce;
2. Illustrate the different parts of the flower; and
3.
demonstrate appreciation on the importance
of animal and plant reproduction.

Code Breaker!
1.As the discussion go along, there are given texts that is enciphered,
decode the term by integrating mathematical concept-the substitution
method.
2. Substitute the number to its corresponding letter:
1 (A), 2 (E), 3 (I), 4 (O), 5 (U).
3. Each correct answer will correspond to a point for the team.

is a biological process in which an organism gives rise to young
ones similar to itself. The offspring grows, matures and turn produces
new offspring. Thus, there is a cycle of birth, growing and death.
Reproduction enables the continuity of the species,
generations after generation.

when offspring is produced by a single parent with or
without the involvement of gamete formation.
when two parents (opposite sex) participate in the
reproductive process involving fusion of male and female
gametes.

It carries the reproductive organ of a plant
that produces the sperm and egg.
The male reproductive organ which has two
parts: the anther and filament.
The anther produces the pollen, which
contains the male sperm cells and the
filament that holds the anther.

A. Self-Fertilization/Self-pollination
A fusion of male and female
gametes produced by the same
individual.
Peanuts, soybeans, orchids,
peas, sunflower, tridax are some
examples for self-pollinating plants.
Types of Plant Reproduction
1. Sexual Reproduction

B. Cross-Fertilization
The fusion of male and female
gametes from different individuals of the
same species.
This occurs in dioecious plants and in
all animal species in which there are
separated male and female individuals.
There are agents for cross
pollination: insects and winds.
Types of Plant Reproduction
1. Sexual Reproduction

A. Binary Fission- a kind of asexual
reproduction where the nucleus of
the parent divides producing
several nuclei and the cytoplasm
separates creating new daughter
cells.
1. Asexual Reproduction

B. Budding- the growth of a small
bulb like projection called bud, or
grows and detaches itself from the
parent cell to grow independently into
a new organism.
Ex. Hydra

C. Fragmentation- the breaking
down of filaments into fragments that
grow into young ones.
Example of organism that go through
fragmentation are molds and starfish.

D. Artificial Vegetative Propagation- the
process of propagating plants through artificial
methods.
Grafting- the method which involves
development of new varieties of plants.
Cutting- involves planting young cutting of
the stem with buds into moist soil.
Layering- involves bending of a young
stem towards the ground and let it grow
under the soil for the development of roots.
Tissue Culture- a mass of tissue is
selected from growing tip of the plants.
This term as callus.

Animals which give birth to live offspring.
Animals which lay eggs.
ANIMAL REPRODUCTION

a female’s egg develops into anew
organism without being fertilized by the
sperm cell.
Examples are aphids, hammerhead
shark, and turkeys.
Asexual Reproduction

• BUDDING
• FRAGMENTATION

A.Hermaphroditism- occurs in animals
where one individual has both male and
female reproductive parts.
They may self-fertilize or may mate
with another of their species, fertilizing
each other and both producing
offspring.
Examples are earthworm, slugs,
tapeworm, snails, barnacles, and
clams.
Sexual Reproduction

Sequential Hermaphrodites- occurs when
an individual reverses its sex during its
lifetime.
Sexual Reproduction
1.Protogynous- individuals start out life as
female and changes sex to male.
Example: wrasse (reef fish)
2.Protandrous- individuals start out life as
a male and change to female.
Example: oyster

Poor reproduction is one of the many factors that contribute to
extinction. Ignite your creativity, create an infographic showing the
importance of animal and plant reproduction.
