How may a plant respond to severe heat stress? how may a plant respond to severe heat stress? by producing heat-shock proteins, which may protect the plant's proteins from denaturing by reorienting leaves to increase evaporative cooling by creating air tubes for ventilation by initiating a systemic acquired resistance response by increasing the proportion of unsaturated fatty acids in cell membranes, reducing their fluidity?

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
