Mass flow or bulk flow system is the movement of substances in bulk or en masse from one point to another point as a result of

(1) Pressure Difference between two points

(2) Osmotic gradient between two points

(3) Concentration gradient between two points

(4) Cannot be predicted

(1) Solids move slowly

(2) Liquid move faster

(3) All move through the same pace

(4) Solids move faster due to high Osmotic pressure

(1) Positive hydrostatic pressure

(2) Negative hydrostatic pressure

(3) Both A and B

(4) Concentration gradient

(1) It is due to positive hydrostatic pressure

(2) It is due to negative hydrostatic pressure

(3) It is due to concentration gradient

(4) All of these

(1) Water, mineral salt

(2) Some organic Nitrogen

(3) Inorganic solutes, Hormones

(4) All of these

(1) System of adjacent cell walls that is continuous throughout the plant

(2) Not continuous path at the place of casparian strips of the endodermis in the roots

(3) Occurs through the intercellular spaces and the walls of the cells

(4) Crosses cell membrane

(1) Dependent on gradient

(2) Water movement is through mass flow

(3) The continuous stream of water gets tension when water is absorbed by root hairs

(4) Mass flow of water occurs due to adhesive and cohesive properties of water

(1) System of interconnected protoplasts

(2) Involves path through plasmodesmata

(3) Water has to enter the cells through the cell membrane

(4) Above a potential gradient movement

(1) Because it involves cytoplasmic streaming always

(2) Molecule has to enter through the cell membrane

(3) Because it is down the gradient

(4) All of these

(1) Apoplast

(2) Symplast

(3) Active transport

(4) Imbibition
