In guard cells when sugar is converted into starch, the stomatal pore
1
closes completely
2
opens partially
3
opens fully
4
remains unchanged.
Official Solution
Correct Option:
(1)
In guard cells when sugar is converted into starch, the stomatal pore closed completely. At night time, the CO2 released during respiration accumulates. As a result, the acidity of the guard cells increases and pH decreases. The decreased pH favours conversion of sugar to starch. Pressure of the guard cells falls and hence they become flaccid. As a result, stomatal aperature closes.

Process by which water enters in the roots due to diffusion, is termed as
1
osmosis
2
passive absorption
3
endocytosis
4
active absorption.
Official Solution
Correct Option:
(2)
Water is absorbed from soil by root system and mainly by root tips. There are two independent mechanisms of water absorption in plants active water absorption and passive water absorption. In active water aborption water is absorbed by the activity of the root itself. In passive water absorption transpiration pull is responsible for absorption of water. According to this theory loss of water from mesophyll cells of leaves in transpiration decreases their T.P. and hence increases their D.P.D. or S.P. As a result of their increased DPD, they absorb water from adjacent xylem vessels of leaves. This xylem of the leaves is in continuation with xylem of stem and roots and hence this pull is transmitted downwards. The pull or tension is removed only when water is absorbed through root hair and this is passive water absorption. Thus transpiration pull is responsible for passive water absorption.

Bidirectional translocation of solutes takes place in
1
parenchyma
2
cambium
3
xylem
4
phloem.
Official Solution
Correct Option:
(4)
The movement of organic food or solute in soluble form from one organ to another organ is called translocation of solutes, e.g., from leaves to stem and roots for consumption. The movement of organic material is bidirectional. Because xylem is responsible for upward movement of water and minerals, so it cannot account for downdard translocation of solute at the same time. Cortex and pith are not structurally suitable for this purpose. Thus only phloem is left where there is end to end arrangement of sieve tubes united by sieve pores which is responsible for translocation of solutes in both direction.

Official Solution
Correct Option:
(4)
Water potential is the difference between the chemical potential of the water in a biological system and the chemical potential of pure water at the same temperature and pressure. The water potential of pure water is zero, and aqueous solutions of increasing concentration have increasingly negative values. Osmotic potential or solute potential is a component of water potential. It can be defined as the amount by which the water potential is reduced as result of the presence of solute in it

Loading of phloem is related to
1
increase of sugar in phloem
2
elongation of phloem cell
3
separation of phloem parenchyma
4
strengthening of phloem fiber.
Official Solution
Correct Option:
(1)
When the phloem cells, just near the source, for example green leaves attain higher concentration of sugars, it is called the process of phloem loading. Sucrose is photosynthesised in the chloroplasts of mesophyll cells of leaves. Mesophyll cells are connected with each other | through plasmodesmata. Similarly plasmodesmata are also present between the mesophyll cells and companion cells and also between mesophyll cells and sieve tubes. There plasmodesmata are the 'channels' meant for the passage of sucrose.

When water moves through a semi permeable membrane then which of the following pressure develops?
1
osmotic pressure
2
suction pressure
3
turgor pressure
4
wall pressure.
Official Solution
Correct Option:
(1)
The pressure required to stop the flow of pure water into a solution across a semi permeable membrane is a characteristic of the solution, and is called the osmotic pressure. Thus water will move from a region oflow osmotic pressure to a region of high osmotic pressure. Turgor pressure is the hydrostatic pressure set up within a cell by the water present acting against the elasticity of the wall. Suction pressure when referred to a cell, is the force which is available for taking in water.

1
Transport saturation
2
Uphill transport
3

Official Solution
Correct Option:
(2)
Facilitated transport or facilitated division is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. Facilitated diffusion is mediated by protein channels and carrier proteins. Most transport proteins that mediate facilitated diffusion are very selective and only transport certain molecules. The major classes of proteins involved in facilitated diffusion are aquaporins, ion channels, and carrier proteins. Importantly, neither channels nor carrier proteins require energy to facilitate the transport of molecules; they enable molecules to move down their concentration gradients (downhill transport).

A few drops of sap were collected by cutting across a plant stem by a suitable method. The sap was tested chemically. Which one of the following test results indicates that it is phloem sap ?
1
Acidic
2
Alkaline
3
Low refractive index
4
Absence of sugar
Official Solution
Correct Option:
(2)
The correct option is (B): Alkaline
Explanation:
Phloem sap is spread throughout the plant; it delivers nutrients (mainly sugars) produced during photosynthesis to various parts of the plant. When phloem sap is collected and tested, it will have an alkaline pH due to the presence of amino acids and organic acids, which can contribute to a slightly basic solution.
Here are the other options and why they are incorrect:
A) Low refractive index: Phloem sap may contain sugars as well as other substances. The presence of other solutes can affect the refractive index, making it difficult to identify.
C) Absence of sugar: Sugar is a key component of phloem sap as it transports the products of photosynthesis throughout the plant.
D) Acidic: Phloem sap typically has a slightly alkaline pH due to the presence of amino acids and organic acids.
Thus, the right answer to this question is alkaline.

To solve the given problem, we need to match the terms in List - I with their corresponding descriptions in List - II based on their definitions and characteristics.
Cohesion: Cohesion refers to the attraction between molecules of the same substance. In the context of water, it is the mutual attraction among water molecules due to hydrogen bonding. Therefore, Cohesion corresponds to:
(ii) Mutual attraction among water molecules
Adhesion: Adhesion is the attraction between molecules of different substances. In a biological context, it refers to the attraction of water molecules to other polar surfaces. Therefore, Adhesion corresponds to:
(iv) Attraction towards polar surfaces
Surface tension: This is a property of the liquid surface that allows it to resist an external force due to the cohesive nature of its molecules. It is largely due to cohesion among water molecules, leading to stronger attraction within the liquid on its surface compared to gaseous phases. Therefore, Surface tension corresponds to:
(i) More attraction in the liquid phase
Guttation: This is the process of water loss in liquid form, typically observed in small droplets at the tips or edges of leaves in some plants, usually occurring at night. Therefore, Guttation corresponds to:

2
The movement does not involve crossing of cell membrane
3
The movement is aided by cytoplasmic streaming
4
Apoplast is continuous and does not provide any barrier to water movement
Official Solution
Correct Option:
(3)
The apoplastic pathway refers to the movement of water and solutes across the plant tissues through cell walls and intercellular spaces, without passing through the cell membrane. This type of transport does not include cell-to-cell communication through the cytoplasm. Here is a breakdown of the options:
Movement of water occurs through intercellular spaces and wall of the cells: This is correct, as the apoplastic pathway operates through the spaces between cells and within cell walls.
The movement does not involve crossing of cell membrane: This statement is true for the apoplastic pathway, which specifically avoids crossing cell membranes.
The movement is aided by cytoplasmic streaming: This is incorrect for the apoplastic pathway. Cytoplasmic streaming occurs in the symplastic pathway, where substances move from cell to cell through plasmodesmata.
Apoplast is continuous and does not provide any barrier to water movement: This is generally true until it reaches areas like the Casparian strip in roots, which blocks the apoplast.
Therefore, the correct answer is the option stating that "The movement is aided by cytoplasmic streaming", as it does not pertain to the apoplastic pathway.

Addition of more solutes in a given solution will:
1
Raise its water potential
2
Lower its water potential.
3
Make its water potential zero
4
Not affect the water potential at all
Official Solution
Correct Option:
(2)
The concept of water potential is crucial in understanding how water moves through plant tissues. Water potential ( ) is a measure of the potential energy in water, particularly important in osmosis, which determines the direction and rate of water movement.
Water potential is influenced by the presence of solutes and pressure. It is defined mathematically as:
Where:
= Total water potential
= Solute potential (also known as osmotic potential)
= Pressure potential
Adding more solutes to a solution affects the solute potential ( ). Solute potential is always negative because solutes lower the potential of water. The addition of solutes makes the solute potential more negative, thus lowering the overall water potential ( ). This can be expressed as:
Therefore, the correct answer is:
Lower its water potential.

The correct match between List I and List II is:
A. Heroine - Slow down body function
Heroin, an opioid derived from morphine, is a potent narcotic. It slows down the body’s function by acting on the central nervous system, leading to drowsiness, decreased respiration, and a feeling of euphoria. This matches with the correct description in List II as it inhibits the normal functioning of the brain and the body.
