Q.1. This is not part of apoplast

(a) cell walls
(b) vessels
(c) intercellular spaces
(d) sieve tubes

(d) sieve tubes


Q.2. Symplastic movement is slower than apoplastic movement because

(a) molecule has to enter through cell membrane
(b) it is down the gradient
(c) as it involves cytoplasmic streaming always
(d) all of the above

(a) molecule has to enter through cell membrane


Q.3. Most of the movement in roots through apoplast is due to

(a) endodermal cells are loosely packed and hence no resistance to water movement
(b) medullary cells are loosely packed and hence no resistance to water movement
(c) cortical cells are loosely packed and hence no resistance to water movement
(d) pericycle cells are loosely packed and hence no resistance to water movement

(c) cortical cells are loosely packed and hence no resistance to water movement


Q.4. In plants, this about apoplast and symplast water movement is true

(a) being down a potential gradient
(b) an equal rate of transport
(c) conduction through interconnected protoplasts
(d) assistance by cytoplasmic streaming

(a) being down a potential gradient


Q.5. Pressure in roots develops due to

(a) low osmotic soil potential
(b) rise in transpiration
(c) active absorption
(d) passive absorption

(c) active absorption


Q.6. Which of the following statements does not hold true in context of apoplast?

(a) occurs through intercellular spaces and cell walls
(b) system of adjacent cell walls is continuous all through the plant
(c) crosses cell membrane
(d) discontinuous path at the place of casparian strips of endodermis in roots

(c) crosses cell membrane


Q.7. Pick the incorrect statement regarding apoplast movement

(a) movement of water is through mass flow
(b) gradient-dependant
(c) mass flow of water takes place as a result of cohesive and adhesive properties of water
(d) continuous water stream gets tension when water is absorbed by root hairs

(d) continuous water stream gets tension when water is absorbed by root hairs


Q.8. In roots, most of the water flows through

(a) Symplast
(b) Apoplast
(c) Imbibition
(d) Active transport

(b) Apoplast


Q.9. Movement of water through apoplast stops at the level of …………… and crosses membrane to undergo symplast till xylem cells

(c) endodermis
(d) all of the above

(d) all of the above


Q.10. In plants, water movement is

(a) up the potential gradient in both symplast and apoplast
(b) down the potential gradient in apoplast and up the potential gradient in symplast
(c) down the potential gradient in both symplast and apoplast
(d) down a potential gradient in symplast and up the potential gradient in apoplast

(c) down the potential gradient in both symplast and apoplast
