#plant water transport MCQ

5 public questions tagged with this topic.

Apoplastic pathway is blocked at endodermis by:

C fits best: Casparian strip. Keep the WATER TRANSPORT basics straight and Casparian strip stands out as the precise answer. Avoid: A) Suberin lamella; B) Middle lamella; D) Plasmodesmata. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Transmembrane pathway requires water to cross membranes:

Pick C: Multiple times. Thinking through WATER TRANSPORT step by step rules out the lookalikes and leaves Multiple times. Skip these: A) Once; B) Twice; D) Not at all. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Symplastic pathway involves movement through:

The right choice is C: Plasmodesmata. In WATER 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) Cell walls; B) Intercellular spaces; D) Xylem. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Apoplastic pathway involves movement through:

That points to C: Cell walls. Compared with the other options, Cell walls is the one that correctly describes the WATER TRANSPORT concept. The wrong ones are A) Cytoplasm; B) Plasmodesmata; D) Vacuoles. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Water absorption by roots is mostly:

B fits best: Passive. Keep the WATER TRANSPORT basics straight and Passive stands out as the precise answer. Avoid: A) Active; C) Energy-dependent; D) Carrier mediated. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.
