The ultimate cause for the movement of water against gravity in a tree is
osmosis
imbibition
transpiration
photosynthesis
When a piece of potato is kept in ahighly concentrated salt solution, then
potato is plasmolysed
potato is deplasmolysed
potato cells get bursted
there is no effect due to istonic solution
To initiate cell plasmolysis, the salt solution should be
isotonic
hypertonic
hypotonic
eletrolysed
When water enters the plant cell, then pressure exerted on the cell wall is called
root pressure
turgor pressure
suction pressure
osmotic pressure
Which of the following elements are essental for the photolysis of water?
Ca and CI
Mn and CI
Zn and I
Cu and Fe
Water lost by transpiration
pure water
rich in solutes
rich in dissolved
rich in dissolved minerals
When water moves through a semipermeable membrane, which of the following is created?
OP
SP
TP
WP
Barometer is used for measuring
relative humidity
osmosis pressure
atmospheic pressure
Stem in higher plants transport water and minerals from
roots to the stems
stems to the roots
leaves to the roots
roots to the leaves
Ganong's potometer is used to measure
guttation
