Solve this problem, showing all work necessary both neatly and clearly on your work packet (clear work includes units!). Round your answers to the correct number of significant figures, write a unit, and draw a box around your answers on your work packet. Enter your answers, rounded to the correct number of significant figures and without a unit, into the boxes below. Any work requiring dimensional analysis must be completed with a process that clearly shows the cancelling of units and that uses conversion factors given on this quiz or discussed in this class for the possibility of full credit.    Periodic Table  (click to expand, do not click to download or it may affect Honorlock)   Answer on Canvas: 1 pointWork Packet: 6 points   Calculate the molar mass, in g/mol, for each substance below.

The _________________ cells are responsible for most photosynthesis in C3 plants. 

Conifers only contain this type of vascular cell__________________. 

_________________ describes the positive pressure exerted by water on cell membranes. 

The following figure shows a light response curve for a forest canopy, a shoot in the forest, and an individual needle on a shoot in the forest. What parts of a light response curve do numbers 1, 2, and 3 indicate? (3 points) Explain why the light response curve for a forest canopy might look so different than that of an individual needle on the shoot. (5 points) Why is photosynthesis negative on this figure? (2 points)

The C4 photosynthetic pathway evolved as an adaptation to minimize photorespiration. What is photorespiration and why does it occur?  (4 points) Explain how the C4 pathway minimizes photorespiration compared to C3 photosynthesis. (3 points) Given this information, how should C3 and C4 plants respond to elevated temperatures? (3 points)
