However, when experimentally raising co2 concentrations to anticipated ad 2050 levels, while at the same time exposing plants to the increased drought conditions expected by mid-century due to climate change, dr. ainsworth is finding a sharp reduction in photosynthetic rate, resulting in reduced growth rate, and predicted loss of food production in crop plants as the climate and atmospheric co2 concentrations continue to change. what is a likely explanation for this observation?

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
