Term / Concept: Definition:
The principal mean of intercellular communication within
PHYTOHORMONES plants are the hormones, also called as ___.
HORMONES Chemical signals produced by cells that act on target cels to
control their growth or development.
AUXINS THE GROWTH HORMONE; THE FIRST PLANT HORMONE TO BE
DISCOVERED.
INDOLE-3- MOST WIDELY DISTRIBUTED NATURAL AUXIN.
ACETIC ACID
AN OCCURENCE THAT INVOLVES PLANTS BENDING OR MOVING AWAY
PHOTOTROPISM FROM THE LIGHT.
GROWTH IN RESPONSE TO GRAVITY, ENABLES ROOTS TO GROW DOWNWARD INTO THE SOIL AND
GRAVITROPISM SHOOTS TO GROW UPWARD AWAY FROM THE SOIL, RESPONSES THAT ARE ESPECIALLY CRITICAL
DURING THE EARLY STAGES OF GERMINATION.
APICAL IN MOST HIGHER PLANTS, THE GROWING APICAL BUD INHIBITS THE
DOMINANCE GROWTH OF LATERAL (AXILLARY) BUDS.
LATERAL COMMONLY FOUND ABOVE THE ELONGATION AND ROOT HAIR ZONE AND
ROOTS ORIGINATE FROM SMALL GROUPS OF CELLS IN THE PERICYCLE.
ABSCISSION THE SHEDDING OF LEAVES, FLOWERS, AND FRUITS FROM THE LIVING
PLANT.
ABSCISSION THESE PART ABSCISE IN A REGION CALLED THE ___.
ZONE
FRUIT SET SUCCESSFUL POLLINATION INITIATES OVULE GROWTH.
GIBBERELLINS REGULATORS OF PLANT HEIGHT; FIRST DISCOVERED IN JAPAN BY
KURUSOWA.
INTERNODAL
ELONGATION KNOWN AS ‘BAKANAE’ OR FOOLISH SEEDLING DISEASE OF RICE.
GIBBERELLA IT WAS DISCOVERED THAT THE ELONGATION WAS DUE TO THE ACTION
FUJIKUROI OF A SUBSTANCES PRODUCED BY A FUNGUS, ___.
CYTOKININS WERE DISCOVERED IN THE SEARCH FOR FACTORS THAT STIMULATE
PLANT CELLS TO DIVIDE.
LEAF AN ACTIVE PROCESS INVOLVING REMOBILIZATION OF NUTRIENTS FROM
SENESCENCE SENESCING LEAVES TO OTHER PARTS OF THE PLANT.
ETHYLENE THE GASEOUS HORMONE THAT REGULATED FRUIT RIPENING.
