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 .
