STOMATA MOVEMENT +PYQS

DCMU inhibits stomatal opening by inhibiting:

Photosynthetic electron transport (B) is correct here. This is core STOMATA MOVEMENT: once you know the definition or pathway step, Photosynthetic electron transport is the clear fit. The wrong ones are A) Respiration; C) Ion channels; D) ATP synthesis in mitochondria. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

MINERAL Transport+PYQS

After crossing endodermis, ions enter the:

The right choice is C: Xylem. In MINERAL Transport, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Cortex; B) Phloem; D) Epidermis. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
