What are potential outcomes when a plant's stomata close in response to heat and water stress? Select all that apply. CO2 and O2 may compete for the active site of rubisco. Photorespiration is more likely to occur. Photosynthesis is more efficient. Gas exchange comes to a halt.
Which of the following statements is are TRUE? Ca pathway involves a single C02 fixation step. In CAM plants. stomata are open during day time. Chlorophyll pigments absorb maximum light in the green wavelength. Reaction center of PSI is P700
Photorespiration becomes more likely when a. CO2 concentrations are high in leaf cells. b. stomata remain closed in C3 plants. c. glucose concentrations are low in leaf cells. d. ATP binds to rubisco.
The turgor loss point of a leaf is equal to:a. the osmotic potential when the pressure potential equals 0b. the pressure potential when the osmotic potential of the leaf cells are at full turgorc. 0d. the water potential when the osmotic potential equals 0
Choose all the correct statements for the graph above: A.in a mutant plant that makes TWICE the normal number of stomata on the leaf, we would expect the line to shift down (i.e. water potential would become more negative). B. During the period starting with time B and ending with time D, the water potential in the leaf is increasing. C.Transpiration rates are the highest around time B. D.At time A we expect to see the greatest volume of water moving up the xylem to this leaf.
Which one of the plant growth regulators would you use if you are asked to:(a) induce rooting in a twig(b) quickly ripen a fruit(c) delay leaf senescence(d) induce growth in axillary buds(e) ‘bolt’ a rosette plant(f) induce immediate stomatal closure in leaves.
But how are the two types of mesophyll involved? From what I understand, CO2 enters the stomata, and then the citric acid cycle of the mitochondia in the mesophyll use the carbon atoms do produce glucose, which then goes through phloem loading and it either used or stored. My question, I guess, is how exactly are the two types of mesophyll involved? Is only one used or are both used at different times in the production of the glucose?
Japanese gardeners regularly trim away parts of the root system to assist in dwarfing a Bonsai plant. A plant’s food is obtained through photosynthesis in the leaves; can you suggest why trimming the roots can cause dwarfing?
