I. INTRODUCTION
Plant propagation is the process of creating new plants from a variety of sources:
seeds, cuttings, bulbs and other plant parts. Seeds and spores can be used fo
reproduction (through e.g. sowing). Seeds are typically produced from sexua
reproduction within a species, because genetic recombination has occurred plants grown
from seeds may have different characteristics from its parents. Plant propagation is one of
the most important activities in plant raising for it is very important in producing new plants
based on different ways, procedures and strategies.
II. GOAL
Grow a plant using the newly learned concept in the Biology Class
III. PROBLEM
How to grow a tomato plant through germinating its seeds under certain
conditions?
IV. INITIAL RESEARCH
Seed germination is a process by which a seed embryo develops into a seedling. It
involves the reactivation of the metabolic pathways that lead to growth and theemergence of the radicle or seed root and plumule or shoot. The emergence of the
seedling above the soil surface is the next phase of the plant's growth and is called
seedling establishment.
Three fundamental conditions must exist before germination can occur. (1) The
embryo must be alive, called seed viability. (2) Any dormancy requirements that prevent
germination must be overcome. (3) The proper environmental conditions must exist for
germination.
V. HYPOTHESIS
The tomato seed will germinate if it satisfies the factors affecting seed germination:
proper soil, right amount of moisture, amount of light, oxygen and proper temperature.

VI. EXPERIMENT
A. MATERIALS
1. Tomato seeds – tomato are propagated not through its fruits but through its
seeds. Its seeds can be acquired from its fruit (tomato). It is the product of the
ripened ovule of gymnosperm and angiosperm plants which occurs after
fertilization and some growth within the mother plant.
2. Soil – loam or garden soil or humus – that is what we need to grow the
tomato seed. First, it provides most of the nutrients plants need. Secondly
humus contains a range of microorganisms that break down plant waste and
help roots absorb nutrients from the soil.
3. Container – there must also be a container for the plants. It must have a
hole under so that the water can move freely. Proper coatiner is also very
important I plant growth.
B. OTHER FACTORS AFFECTING PLANT GROWTH
1. MOISTURE – the plant needs proper amount of water. Water is essential to pl
life. To survive, plants need water, as well as nutrients, which are absorbed by t
roots from the soil. Water is transported throughout the plant almost continuou
to keep its vital processes working
2. TEMPERATURE – the plant must be in proper temperature to grow. Not too ho
not too cold. The temperature will greatly influence how the plant grows and h
it develops.
3. LIGHT – the plant also needs light particularly sunlight. They need it especiall
when the cotyledons start to disappear. They need it to make their own food.

4. OXYGEN – the plants need proper amount of oxygen also because it is very
importance in the respiration process. It is also very important for the plant to h
a good growth for it is needed in food making process.
C. PROCEDURES
1. Start by getting tomato seeds form fresh ripe tomatoes. Let it dry first before
planting it on the soil.
2. After they dried up, plant it on a loam soil. We may plant the tomato two to
three inches below the soil but it could also be good even if we plant it above
soil.
3. Since, the tomato plant is not yet germinating, place it in safe, shady place.
seeds do not need too much amount of light first. It must also be having propeamount of moisture. For the seed to germinate, it must also be in a right
temperature (not so cold, not so hot).
4. Continue preserving the moisture of the soil for the seeds to germinate.
Approximately after 2 - 3 days, the seeds will start to germinate.
5. When the seeds start to germinate, still continue preserving the proper
conditions. The plant will start to have its cotyledons that will serve as its nutrien
provider.
6. When the cotyledons start to disappear, it needs to receive proper amount
light, so place the plant in a safe place where it can receive proper amount o
light. It must also receive proper amount of oxygen and proper temperature.
7. Continue taking care of the plants. Always make it sure that the plant is in
proper condition.
8. When the submission is near, transplant the healthiest plant that grew the beall properly in a proper container. Be able to transplant it safely so that it will
continue to live.

VII. RESULTS, ANALYSIS AND INTERPRETATION
DATE OBSERVATIONS PICTURE
8-23
(PLANTING
DAY)
The seeds were planted in the soil.
1. The seeds are in moist soil
2. The seeds were not subjected to
too much sunlight to wait for it to
germinate
These conditions must be present in the
plant for it to germinate properly.
8-25
(two days
after)
The seeds started to germinate
1. The plant to have the little white
thing
This marks the start of the plant
germination. The white thing emergingfrom the seed will make you sure that
the seed had germinated.
9-3
(11 days
after)
Cotyledon leaves started to appear in
one of the plant. (1.1 inches)
These cotyledon leaves will serve as
the nutrient provider of the plant until
the plant can be able to produce its
own food.

9-10
(18 days
later)
True leaves started to appear (2.3
inches)
This signals that the plant needs to
have proper sunlight, air and
temperature for it needs to produce is
own food. The plant also needs to be
taken care properly to grow taller and
healthier.
9-17(25 days
later)
The plant grew taller and developed
more leaves. (3.5 inches)
The plant needs to be taken care still
for it to grow taller and healthier. The
plant must receive proper sunlight,
moisture, air and temperature for it to
make its own food.
This table shows that proper condition
must be present in the seed for it to germinate
properly. The viability of the seed is greatly
dependent on the external and internal
conditions. When the seed started to
germinate, take care properly the plant so that
it grows properly. Well grown plant will give us
good result. Thus, the table shows that proper
attitude in dealing with the tomato plant is
needed for it to grow.

VII. CONCLUSION
Indeed, the tomato seed grew properly in a place where the right condition is attai
hese conditions: soil, moisture, air, temperature and light is very important in making the plant g
roperly. Seed germination is a very delicate procedure. It needs our full effort and cooperatiohe experiment, some seeds may not have grown as healthy as one of the plants mainly beca
ome of them did not receive proper amount of sunlight and nutrients from the soil. Thus, it sho
hat plants must be treated equally and properly. Indeed, for us to be able to grow seeds and p
we must consider them as our brother also. Thus, plant propagation through seed germination
ery complicated way that needs our efforts. Nothing can be impossible if we give our very be
aking care of the plants.
