Step by step
Solved in 2 steps
- It is the term referring to the characteristic leaf structure of C4 plants that enables them to outperform C3 plants in an environment that has high O2 concentration and/or temperature. Unlike C3 and CAM plants, C4 plants, such as corn and sugarcane, have leaves with vascular bundles that are surrounded by a chloroplast-rich vascular bundle sheath, which is further surrounded by the spongy mesophyll.What is the reason behind plants use enzymatic browning as a defense mechanism?What kind of light does the active conformation of phytochrome absorb, and what kind of change does such absorption cause?
- A) The concentration of CO2 is lower inside a plant cell than in the atmosphere (outside the cell). In your own words, describe how the CO2 levels are kept low inside the plant cell and explain why this is necessary. Assume stomata are open. B) Regarding the situation presented in Part A and assuming that the stomata of the plant leaves are closed, would this favour the induction of photorespiration in a C3 plant? Explain. Make reference to relevant molecule or molecules as needed. Please clearly label your responses as A and BWhich phytochrome is sensing the shading and what are the TWO (2) rapid shade avoiding responses? *Why do leaves appear green in the spring and summer and then turnto red or yellow in the fall?
