Understanding +4 | -1

Passive absorption of water is related to all, except

View answer and explanation

Correct option: C

Development of a positive pressure in xylem

Option C (Development of a positive pressure in xylem) is correct because passive absorption of water is driven by transpiration pull, which creates tension (negative pressure) in the xylem, not positive pressure.

Application +4 | -1

Two cells A, B are contiguous. Cell A has osmotic pressure 10 atom, turgor pressure 7 atm and diffusion pressure deficit 3 atm. Cell B has osmotic pressure 8 atm, turgor pressure deficit 3 atm and diffusion pressure deficit 5 atm. The result will be?

View answer and explanation

Correct option: A

Movement of water from cell A to B

Option A (Movement of water from cell A to B) is correct because water moves from a lower Diffusion Pressure Deficit (DPD) to a higher DPD. Cell A has a DPD of 3 atm, while Cell B has a DPD of 5 atm.

Which of the following cells are not related to the structure of stomata?

View answer and explanation

Correct option: A

Sclerenchymatous cells

Option A is correct. Sclerenchymatous cells are not directly related to the structure of stomata; they provide support and rigidity to other plant tissues.

Water potential of pure water is standard temperature is equal to

View answer and explanation

Correct option: C

Zero

Option C is correct because the water potential of pure water at standard temperature is defined as zero.

335 Hard

335 of 344

Understanding +4 | -1

Which of the following is appropriate for mass-flow hypothesis?

View answer and explanation

Correct option: D

All of the above

Option D (All of the above) is correct because transpiration pull, water absorption, and ion absorption are all related to the mass-flow hypothesis.

336 Hard

336 of 344

Understanding +4 | -1

{\psi _s} = {\psi _p}

View answer and explanation

Correct option: C

Turgid cell

Option C (Turgid cell) is correct because in a fully turgid cell, the pressure potential (

\psi_p

) is equal in magnitude but opposite in sign to the solute potential (

\psi_s

), so the magnitude is equal.

337 Medium

337 of 344

Analyzing +4 | -1

Select the incorrect pair from the following.

View answer and explanation

Correct option: D

Phloem transport - B, Cu

Option D (Phloem transport - B, Cu) is correct because while Boron (B) is involved in phloem transport, Copper (Cu) is not directly associated with it. Copper is more related to redox reactions.

338 Easy

Understanding +4 | -1

Choose the correct statements regarding guttation and pick the correct option from the codes given below
I. It occurs through specialised pore called hydathode
II. Hydathodes can be located on the margin and tips of leaves
III. It occurs in plants growing under condition of low soil moisture and high humidity
IV. It occurs in herbaceous plants when root pressure is low and transpiration is high

View answer and explanation

Correct option: A

I and II

Option A (I and II) is correct because guttation occurs through hydathodes, which are located on the margins and tips of leaves.

The first process by which water enters into the seed coat when a seed is placed in suitable environment for germination is

View answer and explanation

Correct option: D

Imbibitions

Option D (Imbibitions) is correct because imbibition is the initial process of water absorption by the dry seed coat.

340 Hard

Understanding +4 | -1

PH of guard cells increases during day time due to?

View answer and explanation

Correct option: A

Efflux of

{H^ + }

Water channels are possessed by a membrane to facilitate the movement of hydrophilic substances.
These channels are made up of

View answer and explanation

Correct option: B

Eight different type of aquaporin

Option B (Eight different type of aquaporin) is correct because water channels are made up of eight different types of aquaporins.

343 Easy

343 of 344
