THE CYCLE OF PLANT

GERMINATION

PHOTOSYNTESIS

POLINATION AND

FERTILIZATION

Germination is the development of a seed from its

embryonic form to the birth of a new plant.

Factors that influence in germination are :

Internal

External

Base on cotyledon,it’s derived into :

The steps of germination processes are :

• Epygeal

• Hypogeal

Imbibition

Embryo is grow

and develop

PHOTOSYNTESIS

is a process of taking inroganic material to make new organic matter through the combining of carbon dioxide and water using solar energy.

THIS PROCESS ONLY OCCURS IN GREEN PLANTS, BLUE-GREEN ALGAE, AND CERTAIN

BACTERIA.

DESCRIPTION ABOUT THE PROCESS PHOTOSYNTESIS :

• what allows the plants to make their own food• allows the chlorophyll inside each leaf to capture

energy. • The captured energy is used to build

carbohydrates from simple raw materials. (water, carbon dioxide and minerals) These carbohydrates, also known as sugar, are the plants food.

• The plant uses some of the sugar, but also stores some.

ADVANCED :

• Photosynthesis also needs the following raw materials to function: carbon, oxygen and hydrogen.

• Animals breath out carbon dioxide, so this gives the plants oxygen and carbon.

• Plants receive the hydrogen through water. • The materials enter the plant either at the roots

or the leaves.

POLLINATION AND FERTILIZATION PROCESS

Grains / pollen on the stigma attached

Reed powder form ( 2 core , the vegetative nucleus and generative nucleus ) runs toward the micropyle ( doors bladder institutions )

Generative nucleus divides

2 Sperm nuclei

Reach the micropyle

Dead vegetative nucleus

One sperm fertilizes the egg nucleus

Embryos

The other sperm nucleus fertilizes the endosperm nucleus

Bladder agencies ( food reserve for the embryo ) .

Because fertilization takes place two times then fertilization on Angiospermae called double fertilization .
