STOMATA MOVEMENT +PYQS

Primary driving force for stomatal movement is:

B fits best: Turgor pressure of guard cells. Keep the STOMATA MOVEMENT basics straight and Turgor pressure of guard cells stands out as the precise answer. Avoid: A) Osmotic pressure of epidermal cells; C) Capillary action; D) Diffusion pressure deficit. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

WATER POTENTIAL+PYQS

A plant wilts when turgor pressure becomes:

Zero (C) is correct here. This is core WATER POTENTIAL: once you know the definition or pathway step, Zero is the clear fit. The wrong ones are A) Maximum; B) Negative; D) Positive. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

WATER POTENTIAL+PYQS

Positive pressure potential is also called:

C fits best: Turgor pressure. Keep the WATER POTENTIAL basics straight and Turgor pressure stands out as the precise answer. Avoid: A) Tension; B) Matric force; D) Osmotic pressure. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

BASICS of PLANT+PYQS

Wall pressure is exerted by:

Pick B: Cell wall on protoplast. Thinking through BASICS of PLANT step by step rules out the lookalikes and leaves Cell wall on protoplast. Skip these: A) Protoplast on wall; C) Vacuole on wall; D) Plasma membrane. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

BASICS of PLANT+PYQS

Turgor pressure is exerted by:

Protoplast on cell wall (B) is correct here. This is core BASICS of PLANT: once you know the definition or pathway step, Protoplast on cell wall is the clear fit. The wrong ones are A) Cell wall on protoplast; C) Vacuole on nucleus; D) Membrane on cytoplasm. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
