- Suppose you are trying to grow a vascular plant in an extremely humid environment. How would you expect this environment to affect the transpiration rate? The transpiration rate will increase. The transpiration rate will decrease. O The transpiration rate will not be affected. More information is required to make a determination.Stomata are usually opena. at night, when the plant requires a supply of oxygen.b. during the day, when the plant requires a supply of carbondioxide.c. day or night if there is excess water in the soil.d. during the day, when transpiration occurs.e. Both b and d are correct.II. Plant A. Explain how respiration takes place in plants in: Roots Leaves Stem
- Which of the following represents the movement of gases through the open stomata of a leaf during the day? Gas in to leaf Gas out of leaf А. охуgen Carbon dioxide В. Water vapor Carbon dioxide C. Carbon dioxide Oxygen D. Oxygen Water vapor A D O BThe formation of an air bubble in the xylem is called a. agitation. b. cohesion. c. adhesion. d. cavitation.Rubisco can bind with CO2 or 02. When it binds with O2, it "wastes" some of the energy captured from the sun. This reaction is photorespiration and is favored at high temperatures and low CO2:02 ratios. Which of the following strategies should limit photorespiration (select all that apply). Keep stomata closed. Keep stomata open. Physically separate the light and light-independent reactions. Temporally separate CO2 uptake and fixation.
- You have to design a leaf that has been adapted to grown in a dry environment by limiting transpiration. In your design you have to include at least four (4) adaptations and explain how this adaptation will contribute to the plant’s ability to grow in these conditions.(a) Define the following terms i. Transpiration ii. Osmosis iii. Capillary action iv. Surface tension (b) Write down the structure and functions of tracheids in xylem tissue?O b. Green plants do not have asex oduction. Green plants differ from the algal Charophycea in: Green plants do not have growth throughout the whole length of the stem. a. O c. Green plants have seeds. d. Green plants have vascular tissue. O e. Green plants use phragmoplasts.

Group of answer choices it will come out of both. it will come out for xylem but go in of phloem. it will go in for xylem but come out of phloem. it will go into both.In hot, dry climates, plants have evolved mechanisms to avoid photorespiration. Which of the following is FALSE Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d C3 plants have no mechanism to avoid photorespiration C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light- independent reaction in the bundle-sheath cells CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata closed during the day C4 plants include corn, sugarcane, and many grasses CAM plants can undergo photophosphorylation in the absence of sunlight 7 Open in ReadinWhich of the following plant structures is necessary for transpiration to occur? a.
