Jasmonic acid

Jasmonic acid biosynthesis occurs via which pathway?

Correct option is C, Octadecanoid pathway. In Jasmonic acid problems like this, the accurate statement is Octadecanoid pathway; the others are common mix-ups. Not these: A) Shikimate pathway; B) Mevalonate pathway; D) Phenylpropanoid pathway. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Jasmonic acid

The primary precursor of jasmonic acid biosynthesis is:

C fits best: α-linolenic acid. Keep the Jasmonic acid basics straight and α-linolenic acid stands out as the precise answer. Avoid: A) Oleic acid; B) Linoleic acid; D) Arachidonic acid. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Striglactone

The immediate apocarotenoid precursor of strigolactones is:

The right choice is B: Carlactone. In Striglactone, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Orobanchol; C) Strigol; D) GR24. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Striglactone

Initial steps of strigolactone biosynthesis occur in:

C fits best: Plastids. Keep the Striglactone basics straight and Plastids stands out as the precise answer. Avoid: A) Cytosol; B) Mitochondria; D) Nucleus. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Striglactone

Strigolactone biosynthesis starts from which precursor?

C fits best: β-carotene. Keep the Striglactone basics straight and β-carotene stands out as the precise answer. Avoid: A) Linolenic acid; B) Mevalonate; D) Squalene. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.
