The document provides details about a science lesson on the reproductive parts of flowering, non-flowering, and cone-bearing plants. It includes illustrations and descriptions of the parts of various plants. Students observe flowers to identify reproductive structures like stamens and pistils. They also learn about the spores and life cycles of ferns and conifers. Activities include labeling diagrams of plant parts and arranging stages of life cycles. The lesson aims to teach students the different reproductive structures and processes in various types of plants.

see? What do you call this part?
Petals - are most attractive part of all
floral parts, purposely to attract insects.
Flower - reproductive organ of a plant
that produces the egg and sperm.

11. Finding practical applications of concepts and skills in daily living.
Read the situation below then answer the
question that follow.
You saw a group of boys and girls
picking flowers in the park. They
made fun of these by removing the
petals one by one.
What would you tell them?
Why are flowers important to plants?

12. Making generalizations and abstractions about the lesson .
1.What are the necessary parts of
the flower?
2.What are the reproductive parts of
the flower?

13. A complete flower has the following
parts: receptacle, sepals, petals,
stamens, and pistils (carpels )
• receptacle- is the enlarged upper
end of flower stalk which bears the
flower or group of flowers.
Petals - the brightly colored parts that
attracts insects during pollination.
A group of petals is called corolla

14. • sepals - are modified leaves which
enclose and protect the other parts
of a flower when it is still a bud.
• When a flower blooms the
sepals supports the bottom of
the flower.
• A group of sepals is called Calyx

15. stamen – the male part of a flower. It
consist of filament and anther
1.filament- holds the anther in a position
tall enough to release the pollen.
2.anther- consist of two lobes that
contain pollen sacks.it has pollen grains
that are released by the anther when it
matures.
3. pollen grains- contain the male
gametes.

16. Pistil or carpel is the female part of
the flower. It consists of the stigma,
style and ovary.
1. ovary - contains two or more
ovules. Within the ovule is the female
games or egg cell called ovum.
2.style- a stalk that connects the
stigma to the ovary, tall enough to
trap the pollen grains.

17. 3.stigma – a swollen structure
at the end of the style
• It receives the pollen grains.
• Mature stigma secretes a fluid
that stimulates the pollen grains
to germinate.

34. Review
Game: “Passing the Box”
Pupils will pass the box as they sing “
Bubuka ang Bulaklak”.
When the music stops the one who is
holding the box will get a cartolina strip
reads and answers what is described
there.

35. Establishing a purpose for the lesson;
Many plants have flowers that
help them to make seeds in order to
reproduce. However, some plants do
not use flowers to reproduce. These
plants are called non-flowering
plants.
What do you think is their
reproductive part? Let’s find out.

36. Presenting examples/ instances of the lesson
Activity Proper
“ A Trip to the Garden “
I. Problem: What is the reproductive part of spore-bearing plants?
II. Materials: live fern plant, pen and paper
III. Procedures:
1. Bring pupils to the school garden.
2. Instruct them to go in pairs.
3. Look for a non-flowering plant like fern.
4. Observe the appearance and body parts. Examine
closely the leaves of the plants. Note down the
structures observed from the plants. (They can even
bring camera with them and take photos of the plants.)
5. Teacher can introduce the word spores and further explain about it. Life cycle of
the fern can also be tackled during the field observation.
6. Throughout the field observation, observe and give specific feedback relevant
to what the pupils are expected to do.
7. When the pupils are finished tell them to leave the
area without picking any specie or live plants.

37. Guide questions:
1. What non- flowering plants did you
observe in the garden?______
2. What structure did you see in ferns?__
3. Where did you find them? __________
4. How will you describe spores?
__________
5. Why is life cycle of ferns different from
most of the plants?______
(See illustrations in the next slide to answer the above questions)

40. Discussing new concepts and practicing new skills #2
Look at the diagram, how will you describe the ferns’ life cycle
Why are spores important to ferns?

42. Finding practical applications of concepts and skills in daily living.
Nina took a walk in the garden and
saw a small plant with feather-like
arrangements of leaves. She was amazed
upon looking at the undersides of the
leaves and immediately gathered the
blackish brown spots found in it. Did
Nina show the right behavior? Why?

43. Background Information for Teacher
Spore bearing plants have slightly different life
cycles from most plants. They produce spores from
one parent plant. The spores fertilized themselves
and develop into plants identical to their parents.
Stages of Fern Life Cycle
1. Frond Stage-formation of leaves that grow
from rhizomes called fronds .
2.Sorus Stage-development of small
brown dots or patches called sori

44. 3. Sporangium Stage-Mature
sporangium shrinks, breaks and
release the spores in air. When fall in
moist place, germinate and develop
a vegetative cell
4. Prothallus stage- continued cell
divisions results in the formation of a
heart-shaped prothallus

45. 5. Archegonium and Antheridium Stage-
development of the female sex organ
called archegonium and male sex organ
antheridium
6. Fertilization Stage- Sperm and egg
mature ; antheridium breaks causing the
sperm to swim in water archegonia
opens and sperms enter. One sperm
fertilizes each egg that result the
formation of zygotes.

46. 7. Embryo Fern Stage- zygote
undergoes cell division after fertilization.
The development produces the embryo
fern which consists of a foot anchored in
the tissue of the prothalllus: a root and a
leaf .

47. Evaluation
Read the sentences carefully. Write TRUE if the statement
is correct and FALSE if it is not.
__1. Spores are the reproductive cells of
all non- flowering plants.
__2. Spore-bearing plants have slightly
different life cycles from most of the
plants.
__3. Spores are produced in structures
called sori.

48. __4. In a spore –bearing plants, both
parents contribute to the formation of
spores.
__5. Ferns reproduce by means of
producing spores the blackish brown
spots underside of the leaves.
Assignment
1. Aside from ferns what other plants are
spore-bearing? List atleast 5.

produce both male and female cones.
---Male cones produce the pollen grains with
sperm cells
