PHOTOPERIODISM+PYQS

Interruption of dark period by red light in short day plants results in:

Go with C — Inhibition of flowering. Under PHOTOPERIODISM, 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) Flowering; B) No effect; D) Early flowering. When two options sound similar, choose the one that matches the textbook definition most tightly.

PHOTOPERIODISM+PYQS

In short day plants, flowering occurs when there is:

The right choice is B: Low or absence of Pfr. In PHOTOPERIODISM, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) High Pfr; C) Continuous red light; D) High Pr accumulation. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

PHOTOPERIODISM+PYQS

Plants that require day length shorter than critical photoperiod for flowering are:

Correct option is B, Short day plants. In PHOTOPERIODISM problems like this, the accurate statement is Short day plants; the others are common mix-ups. Not these: A) Long day plants; C) Day neutral plants; D) Annual plants. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
