In Exercises 1-4, describe the level surface F(x, y, z) = 0.
\(F(x, y, z)=x^{2}+y^{2}+z^{2}-25\)
Text Transcription:
F(x, y, z) = x^2 + y^2 + z^2 - 25
- C3 plants vs. C4 plants o Due to differences in enzymatic discrimination C3 plants are isotopically distinct from C4 plants o All plants depleted in 13C relative to atmospheric CO 2 o " 12CO and 13CO behave differently in photosynthetic pathways ⇒ 13CO diffuses o 2 2 2 more slowly - Wide range of δ13C values in C3 plants related to water stress o Plants that close their stomata during drought, the plant has to be less and less choosy about what type of carbon it can use for photosynthesis o The less 13C there is being used, the more choosy the plant could be, the more water their was available ▪ Can afford to be picky o The more 13C there is being used, the less choosy the plant could be the more water stress it was under ▪ Cannot afford to be picky o The more negative the number is, the less 13C it has Less 13C More 13C " o - Attendance Quiz #3 o Why are plants more depleted of 13C than the atmosphere ▪ Enzymatic discrimination ⇒ want 12C more o Why are C3 plants more depleted of 13C than C4 plants ▪ C3 plants have Rubisco that is more choosy than PEPcase in C4 o Why are water-stressed
