Transport in Plants Assertion and Reason Questions for NEET
In each of the following questions, a statement of Assertion (A) is given and a corresponding statement of Reason (R) is given just below it. Of the statements, pick the correct answer as :
Assertion : Stomata are often called turgor operated valves. Reason : The opening and closing of stomata are caused by gain and loss of turgidity by their guard cells.
Assertion : Turgor pressure is essential for cell enlargement during growth. Reason : Turgor pressure generates the stress that leads to the expansion of plant cell wall during growth.
Assertion : Sucrose is the most suitable form of carbohydrate translocation. Reason : Sucrose is non-reducing and chemically stable that does not react with other substances during translocation.
Assertion : Diffusion is more rapid when the difference of concentration is larger. Reason : Diffusion occurs in all directions through the available space
Assertion : Plasmolysis is involves shrinkage of protoplast from the cell wall. Reason : Plasmolysis is a result of endosmosis
Assertion : Apoplast pathway is the rapid means of movement of water through cells. Reason : Apoplast pathway is affected by the metabolic state of root cells.
Assertion : Aquaporins are membrane proteins for active transport of water soluble substances. Reason : Aquaporins transport substances along the concentration gradient.
Assertion : The concentration of minerals in the soil is usually lower than the concentration of minerals in the root. Reason : Most minerals enter the root by active absorption into the cytoplasm of its epidermal cells.
Assertion : Semipermeable membrane allows passage of some selected solutes to a limited extent only. Reason : Semipermeable membrane is used in measurement of osmotic potential.
Assertion : Transpiration is lower in the still air. Reason : Water vapours accumulate around the transpiring organs and reduce the DPD of the air.
Transport in Plants Figure-Based Questionsย for NEET
Consider the given figure of Spirogyra cells in an experiment and answer the following questions.
(a) Identify A, B, C and D.
A.ย The given figures, A, B, C and D represent turgid, incipiently plasmolysed, plasmolysed and deplasmolysed cells, respectively.
(b) Give reasons why protoplast shrinks during plasmolysisand expands during deplasmolysis.
A.ย Shrinkage of protoplast during plasmolysis occurs due to exosmosis under the influence of hypertonic condition and expansion during deplasmolysis occurs due to endosmosis under the influence of hypotonic condition.
(c) What are the various precautions that should be taken during the above experiment?
A.ย The precautions are as follows: (i) The experimental material (Spirogyra filament) must be fresh and living. (ii) The external solution must not be too strong as to become toxic. (iii) Wash at least once the experimental material with external solution so that chances of dilution are minimised. (iv) For deplasmolysis, the material has to be washed at least twice with water.
