#plant transport MCQ

7 public questions tagged with this topic.

Apoplastic transport mainly occurs through:

Pick C: Cell wall. Thinking through PSS- Sec-F-Transport step by step rules out the lookalikes and leaves Cell wall. Skip these: A) Plasmodesmata; B) Cytoplasm; D) Vacuole. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Water movement between xylem and phloem mainly occurs at:

C fits best: Source and sink regions. Keep the PHLOEM TRANSLOCATION basics straight and Source and sink regions stands out as the precise answer. Avoid: A) Root only; B) Leaf only; D) Stem nodes. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Main sugar transported through phloem is:

Correct option is C, Sucrose. In BASICS of PLANT problems like this, the accurate statement is Sucrose; the others are common mix-ups. Not these: A) Glucose; B) Fructose; D) Starch. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Phloem tissue transports mainly:

Correct option is C, Sugars. In BASICS of PLANT problems like this, the accurate statement is Sugars; the others are common mix-ups. Not these: A) Water; B) Minerals; D) Lipids. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

In gymnosperms, water transport mainly occurs through:

The right choice is C: Tracheids. In BASICS of PLANT, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Vessels; B) Sieve tubes; D) Companion cells. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Water conduction in angiosperms occurs mainly through:

Correct option is B, Vessels. In BASICS of PLANT problems like this, the accurate statement is Vessels; the others are common mix-ups. Not these: A) Tracheids; C) Fibers; D) Parenchyma. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Xylem tissue mainly transports:

C fits best: Water and minerals. Keep the BASICS of PLANT basics straight and Water and minerals stands out as the precise answer. Avoid: A) Food; B) Hormones; D) Proteins. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.
