How cells know whether sister kinetochores are properly attached to the mitotic spindle?

#SCPH06 I Botany
  1. When sister chromatids are correctly attached to microtubules, their kinetochores are under tension. Mitotic spindle attached to the kinetochores pull at them, and the cohesin molecules that hold the sister chromatids together withstand these forces, creating tension at kinetochores.
  2. When sister chromatids are correctly attached to microtubules, their kinetochores are not under tension. One kinetochore attaches to microtubules emanating from two opposite spindle poles.
  3. When sister chromatids are correctly attached to microtubules, their kinetochores are not under tension. Both sister kinetochores attach to microtubules emanating from the same spindle pole.
  4. When sister chromatids are correctly attached to microtubules, their kinetochores are not under tension. Only one of the two sister kinetochores attaches to microtubules.

NH4+ is toxic to plants, inhibit dinitrogenase and also interfere energy metabolism by dissociating ATP formation  from ETC  in both mitochondria and chloroplasts. What will plant cells do to avoid this problem?

a) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into nitrate

b) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into amino acids

c) The pathway for this conversion involves the sequential actions of glutamine synthetase (GS) and glutamate synthase (GOGAT)

d) The pathway for this conversion involves the sequential actions of Aspartate aminotransferase (Asp-AT) and Asparagine synthetase (AS)
