#transport in plants question

7 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.

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 movement in soil-plant-atmosphere continuum occurs only if Ψ:

Pick B: In specialized tissues. Thinking through WATER POTENTIAL step by step rules out the lookalikes and leaves In specialized tissues. Skip these: A) In all cells equally; C) Only in roots; D) Only in leaves. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

DPD (Diffusion Pressure Deficit) refers to:

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

In plant systems, water potential is generally:

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

Water potential of pure water at standard conditions is:

Go with C — Zero. Under WATER POTENTIAL, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Positive; B) Negative; D) Variable. When two options sound similar, choose the one that matches the textbook definition most tightly.
