17443.	Question : Given figure shows U-shaped tube with two hands A and B separated by a semi-permeable membrane (i) Adding solute to the right side lowers the value of Psi_(s) Causing water tomove to the right side of the tube. (ii) Applying positive pressure to the left side decreases the vaule of Psi_(rho) causing water to move to the right side of the tube. (iii) Applying negative pressure to the left sidedecreases the value of Psi_(rho) causing water to move to the right side of the tube. Which of the above statements is//are true?
Answer» `(i)` and `(ii)` `(i)` only `(iii)`only `(i),(ii)` and `(iii)` Solution :According to the GIVEN figure if solute is added to the right side `Psi_(s)` lowers This CAUSES water to move to the right side of the tube. When positive PRESSURE is applied to the left side `Psi_(rho)` increases causing water to move to the right side of the tube. Simiarly when NEGATIVE pressure is applied to the left side `Psi_(rho)` LOWER which causes water to move to the left side of the tube.

Discussion

17446.	Question : Given figure demonstrates the translocation of organic solutes according to pressure flow hypothesis. Which out of the following statements is incorrect regarding this?
Answer» A continuous high osmotic concentration is maintained in REGION `P`, which loads a sieve tube element by passively transporting solute molecules into it, R shows the movement of `H_(2)O` into sievetube elements from nearby xylem vessels by OSMOSIS Translocation of organic solutes takes place from region `P` with high turgor pressure to region `Q` with low turgor pressure In region `Q` material is either consumed or is converted into insoluble storage forms resulting in decreased osmotic pressure. Solution :In the given figure , region `P` represents the source or supply`i.e.,` leaves where photosynthesis takes place. Region `Q` represents the sink `i.e.,` roots. According ot pressure flow mechanism water containing sugar in solution flows under pressure through the phloem. Glucose is produced by photosynthesis in the mesophyll cells of the green leaves, some of which is converted into non-reducing sugar `i.e.,` sucrose.The sucrose is actively transported to the companion cells of the smallest vein in a leaf and DIFFUSES through the plasmodesmata to sieve tube elements. As a RESULT, concentration of sucrose increases in the sieve tube cells. Water moves by osmosis from the nearby xylem vessels in the leaf vein (shown by `R`) Hydrostatic pressure moves the sucrose and other substances in the sieve tube cells, and then moves them to sink. At sink region, water moves out of sieve tube cells by osmosis, lowering hydrostatic pressure. As the sap is pushed down the phloem sugar is removed by the cortex of both stem and root and is consumed or converted into starch. Starch is insoluble and exerts no osmotic effect. Consequently, the osmotic pressure of the contents of phloem decreases. Finally relatively pure water is left in the phloem and this is though ot leave by osmosis or be drawn back into nearby xylem vessels by suction of the transpiration pull.

Discussion

17448.	Question : Given diagram illustrates the changes that occur when a plant cell takes up water Identify L,Mand N and select the incorrect statement the given diagram
Answer» `N` is the diffusion pressure deficit which becomes zero when `L`and`M` re equal in magnitude. In a flaccid cell value of `N` becomes equal to that of `L` `M`represents osmotic pressure which increases when a flaccid cell takes up water. `L` represents solute potential which decreases with the increase in turgidity of the cell . Solution :Given diagram illustrates the changes that OCCUR when a flaccid plant cell takes up water. `L`represnets osmotic pressure `(OP)` or solute potential `(Psi_(s))`, M represents turgor pressure `(TP)` or pressure potential `(Psi_(rho))` and `N` represents diffusion pressure deficit `(DPD)` or water potential `(Psi_(w))`. In a flaccid cell, `TP` is zero, therefore, `DPD = OP-0=OP.` When a flaccid cell is placed in water it takes up water due to endosmosis `OP` of the cell starts decreasing while `TP` starts increasing. In fully turgid condition `OP` and `TP` become equal so that `DPD` becomes zero.

17450.	Question : Given below is the ultrastructure of animal cell (i) Label the parts marked as 1, 2, 3, 4 and 5. (ii) Give one major function of each of these parts.
Answer» Solution :(i) 1. Mitochondrion 2. Cell membrane 3. RIBOSOMES bound to RER 4. Nuclear envelope 5. Smooth endoplasmic reticulum. (ii) 1. it is the power HOUSE of the cell. It supplies energy for various activities of the cell. 2. It selectively regulates the movement of molecules into and out of the cells. 3. These play a role in protein synthesis. 4. It is an envelope that keeps the nuclear contents in place and distinct from cytoplasm. 5. It PLAYS a role in transport of materials from one part of the cellto ANOTHER.
