Apoplast movement

Find the wrong one.

(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

(1) Cortical cells are loosely packed and hence no resistance to water movement

(2) Endodermal cells are loosely packed and hence no resistance to water movement

(3) Pericycle cells are loosely packed and hence no resistance to water movement

(4) Medullary cells are loosely packed and hence no resistance to water movement

(1) Endodermis impervious

(2) Inner layer of cortex impervious

(3) Outer layer pervious

(4) More than one option is correct

(1) Endodermis of root

(2) Starch sheath

(3) Inner layer of cortex

(4) All of these

(1) Symplast

(2) Apoplast

(3) Both A and B

(4) Depends on gradient

(1) Obligate, seeds cannot germinate

(2) Facultative, fruits cannot disperse

(3) Obligate, roots can not spread down the soil

(4) Facultative, leaves cannot perform photosynthesis.

(1) Pushing pressure

(2) Negative pressure

(3) Tries to cope up with water requirement of well heighted plants

(4) Effects are observed at day time and evening time
