what is Vernalization???????????
What is function of gibberellines
What are the advantages of bolting?
Manganese is required in photolysis of water during photosynthesis,What is the meaning of this statement?
TREATMENT OF SEED AT LOW TEMPERATURE UNDER MOIST CONDITION TO BREAK ITS DORMANCY IS CALLED 1] SACRIFICATION 2] VERNALIZATION 3] CHELATION 4]STARTIFICATION
Desert animals need to conserve water. Kidneys regulate the concentration of salt and water in blood through the formation and excretion of urine. A kidney is composed of approx. 1 million units called nephrons. The kidneys of desert animals have modofied nephrons which help them survive long period without water. Which one of these options would be the expected modification?
1. A very short collecting duct
2. A very long loop of Henle
3. A very short distal tubule
4. A very large Bowman's capsule
What is function of ethylene.
WHAT IS -VE AND +VE ALLOSTERIC MODULATION??
how is the process of vernalisation advantageous to plant..?
what is parthenocarpy..??
give examples of protoplasmic modifications.
teacher , plz give a list of plants that show hypogeal and epigeal germination.
specially mention in which category these plants fall - sunflower, castor, groundnut
List five main groups of natural plant growth regulators. Write a note on discovery, physiological functions and agricultural/horticultural applications of any one of them.
show diffrent phases of growth in plants with conditons?
What is senescence?
differences between photoperiodism & vernalization
What is a-amylase test? (Here 'a' stands for alpha)
Describe briefly:
a)Arithematic growth
b)Geometric growth
c)Sigmoid growth curve
The term heterosis was first coined by...????
THE NATURAL PLANT HORMONES WERE FIRST ISOLATED FROM ...1] CORN GERM OIL & HUMAN URINE 2] COTTON FRUITS SPINACH LEAVES & RICE PLANTS 3] AVENA COLEOPTILE SPINACH LEAVES & THE FUNGUS GIBBERELLA 4]HUMAN URINE & RICE SEEDLING
WHAT ARE THE TYPICAL DIFFERENCES BETWEEN DIFFERENTIATION ,DEDIFFERENTIATION AND REDIFFERENTIATION? EXPLAIN
What would be expected to happen ? If
a-GA3 is applied to rice seedling.
b- a rotten fruit get mixed with unripe fruits.
c-You forget to add cytokinin to the culture medium.
WHAT WAS F W WENT EXPERIMENT OF ISOLATED AUXINS ???????

What is 'Plasmatic Growth'?
Give 3 differences between arithmetic geometric growth.
what is meant by rosette habit?
required for growth
(1) Oxygen provides the medium for enzymatic
activities needed for growth
(2) Water helps in releasing metabolic energy
essential for growth activities
(3) Turgidity of cells help in extension growth
(4) Only microelements are required by plants for
the synthesis of protoplasm and act as source
of energy
what is dormancy and abscission??
decapitaion is largely applied in hedge making and tea plantations .why ?
