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 B
Plant roots are adapted as storage organ( such as potatoes and carrots)Typically photosynthesize during the summer and remain dormant underground during winter. Explain how sugar transport in such a plant would be different during summer, when the plant is photosynthesizing and in the spring when new growth is coming up

Based on Figure 2, identify the structure that regulates the movement of water and minerals towards the xylem in the root ii. Predict what will happen to the transportation of water and minerals through the plasma membrane if the root was poisoned and no cellular respiration occurred. iii. .

- 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.arrow_forwardNitrate and phosphate are important anions for plants.
