7. Which of the following is seen in plants with self-fertilization? a. Each individual plant only produces either male or female flowers b. Male and female flowers are produced in different parts of the plant c. Male and female flowers are produced at different points in time d. Pollen tube is incompatible with stigma from the same plant e. Flower bud never opens, pollen flows directly to the stigma
8. Select one outcome that is NOT the result of the accumulation of salt ions in soil. a. Water potential is altered b. Plants lose turgor pressure c. Plant growth is limited d. Plants have harder time up taking water e. Transpiration will occur at faster rate
9. Utricularia, a carnivorous plant, is very abundant in the everglades. What can you infer about the nutrient composition of the everglades? a. The everglades ecosystem is rich in nutrients b. The everglades ecosystem is poor in CO2 c. The everglades ecosystem is very dry d. The everglades ecosystem is poor in nitrogen e. The everglades ecosystem has no minerals at all
10. Several process allow water to move up the xylem, for some plants even hundreds of meters. Select the process that is NOT involved in xylem flow: a. Adhesion of water molecules to tracheid walls b. Cohesion of water molecules to each other c. Transpiration pulling the water column up d. Osmosis moving water into root cells e. Active transport of ions in xylem vessels 7. Which of the following is seen in plants with self-fertilization? a. Each individual plant only produces either male or female flowers b.

Explanation / Answer

7. e. In certain plants, the anther and stigma lie near each other with the goal that self fertilization takes place. Flower buds do not open and the pollen flows directly to the stigma. This flowers are known as cliestogamous flowers.

8. e. Transpiration rate decreases with the accumulation of salt ions in soil. The plant is unable to absorb water under extreme salinity conditions and wilts.

9. d. The everglade ecosystem is poor in nitrogen. Despite this, nitrogen acts as a highly important limiting nutrient in everglade ecosystem.

10. e. ATP is not required during transport of water in xylem vessels and the process is passive. The ions are carried uo in xylem by mass flow.
