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.
