- If the PIN2 gene is rendered non-functional by mutation it dramatically reduces the speed of the gravitropic response in the root. Explain what PIN proteins do and why the loss on PIN2 would likely affect the speed of the gravitropic response.Describe each of the following types of specialized shoots. Be certain to account for modifications of the leaves, internodes, and orientation of growth: stolon, rhizome, tuber, bulb, corm, and tendril. Each provides a plant with a selective advantage. What is the adaptive value of each type of specialized shoot?Stomata are pores on the surface of plant leaves that allow for gaseous exchange. The numbers below shows the density of stomata on the leaf surfaces of three species of plants. Based on this information, which statement is incorrect? Stomata Density: Elodea (upper epidermis) = 0, (lower epidermis) = 0, Water Lily (upper) = 420, (lower) = 0, Black Walnut (upper) = 0, (lower) = 465 a) Since Elodea does not have any stomata, it does not carry out photosynthesis. b) In Elodea’s aquatic environment, stomata are not used to control gas exchange. c) Since black walnut trees thrive on land, stomata are located on lower surface to decrease the amount of water lost in the heat of the sun. d) Since water lilies live on the surface of water, transpiration occurs from the upper epidermis because that is where it is in contact with air.
- what type of stem modification does: -Pistia stratiotes-Calotropis gigantea-Gloriosa superba-Ficus benghalensis have?Why do many perennial plant species exhibit mast seeding behavior?What is the difference between the apical meristem and lateral meristem? shoot apical meristems lateral meristems root apical meristems Apical meristemic tissue is responsible for primary growth at the root and shoot tips. Lateral meristemic tissue is responsible for secondary growth with an increase in diameter of the stem. Apical meristemic tissue is responsible for secondary growth with an increase in diameter of the stem. Lateral meristemic tissue is responsible for primary growth at the root and shoot tips. Lateral meristematic tissue is only found in annual plants. O Apical meristemic tissue is only found in woody plants.
- What might be an advantage of having the apical meristem near to the ground?Which of the following explains why pea plants in high soil nitrogen conditions have so few rhizobial nodules on their roots? When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.The oat coleoptiles of the seedlings above have been modified: either cut or placed in a light-blocking tube. Which ones will stills bend toward a directional light source?
- In a comparison of the water potential and turgor pressure of leaf cells before and after wilting, which of the following would you expect to find? Select one: a. Water potential: wilted = not wilted; Turgor Pressure: wilted < not wilted b. Water potential: wilted > not wilted; Turgor Pressure: wilted < not wilted c. Water potential: wilted < not wilted; Turgor Pressure: wilted > not wilted d. Water potential: wilted < not wilted; Turgor Pressure: wilted < not wilted e. Water potential: wilted > not wilted; Turgor Pressure: wilted > not wiltedIn the heart embryo stage of Arabidopsis thaliana, there are three key anatomical features that are essential for plant development. The red highlighted cells will become the the yellow highlighted cells will become the and the two "lobes" of the heart will become the suspensor; apical meristem; seed coat basal daughter cell; apical daughter cell; cotyledons shoot apical meristem; root apical meristem; taproots suspensor; shoot apical meristem; taproots root apical meristem; shoot apical meristem; cotyledonsAs plants grow, they tend to align theirstems and roots along the direction of the gravitational field. This tendency, which is related to differential concentrations of planthormones known as auxins, is referred to as gravitropism. As an illustration of gravitropism, experiments show that seedlings placed inpots on the rim of a rotating turntable do not grow in the verticaldirection. Do you expect their stems to tilt inward—toward the axisof rotation—or outward—away from the axis of rotation?
