BASICS of PLANT+PYQS

Primary function of phloem parenchyma is:

Pick B: In specialized tissues. Thinking through BASICS of PLANT 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.

Bryophytes are non-vascular because they lack:

The right choice is C: Xylem and phloem. 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) Roots; B) Leaves; D) Chlorophyll. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Translocation of food in plants occurs from:

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

Sieve cells are characteristic of phloem in:

Gymnosperms (B) is correct here. This is core BASICS of PLANT: once you know the definition or pathway step, Gymnosperms is the clear fit. The wrong ones are A) Angiosperms; C) Monocots; D) Bryophytes. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Companion cells are present only in:

Answer: C) Angiosperms. For BASICS of PLANT, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Gymnosperms; B) Bryophytes; D) Pteridophytes. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

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 is primarily composed of:

The right choice is B: Dead cells. 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.

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.

Vascular plants are also known as:

Tracheophytes (B) is correct here. This is core BASICS of PLANT: once you know the definition or pathway step, Tracheophytes is the clear fit. The wrong ones are A) Bryophytes; C) Thallophytes; D) Pteridophytes. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
