Question
Gas exchange in plants occurs through structures called A. Spiracles. B. Gas pores. C. stomata D. Phloem E. None of choices are correct. In plants, vascular tissue that consists of living cells that distribute sugars throughout the plant is called. A. Xylem. B. Phloem. C. Stomata. D. Transport tissue. E. Lichens. What would be the long-term effect of the lymphatic vessels associated with capillary bed were to become blocked? A. More fluid would enter the venous capillaries. B. Blood pressure in the capillary bed would increase. C. Fluid would accumulate in interstitial areas. D. Fewer proteins would leak into the interstitial fluid from the blood. E. Nothing would happen. All of the following normally enter the plant through the roots except: A. Carbon dioxide B. Nitrogen C. Potassium D. Water. E. Calcium. Plants do not have a circulatory system like that of some animals. If a given water molecule did 'circulate' (that is, go from one point in a plant to another and back), it would require the activity of A. Only the xylem. B. Only the phloem. C. Only the endodermis. D. Both the xylem and endodermis. E. Both the xylem and phloem.Explanation / Answer
Answer:
20. C. Stomata
(The exchange of oxygen and carbon dioxide in the leaf occurs through pores called stomata. It normally open during day and close during the night)
21. B. Phloem
22. C. Fluid would accumulate in the interstitial tissue.
(The fluid-filled tissues would swell. A condition is known as edema.)
23. A. Carbon dioxide
(CO2 enters to plant through the stomata of the leaf)
24. D. Both the xylem and endodermis.
(In plant water is transported through the xylem. Movement of water through the endodermis into the center of the root.)
