While walking in the woods, you encounter an unfamiliar flowering plant. Which of the following plant features would help you determine whether that plant is a monocot or a eudicot? (Choose all that are appropriate.) a. size of the plant b. number of seed leaves c. shape of its root system d. number of petals in its flowers e. arrangement of vascular bundles in its stem f. whether or not it produces seed-bearing cones

Your friend plants a new herb (which is a eudicot and a perennial). During the first year, she allows the plants to grow naturally. Her plants grow tall and relatively spindly during the growing season, and when it comes time to harvest, she doesnt have a large yield. What phenomenon is responsible for her poor yield? What could your friend do to increase her yield next year?

Match each flower structure with its function. a. pollen grain b. ovule c. anther d. ovary e. sepal f. petal 1. attracts pollinators 2. develops into seed 3. protects an unopened flower 4. produces sperm 5. produces pollen 6. contains ovules

Many plant species can reproduce both sexually and asexually. Which mode of reproduction would generally be more advantageous in a location where the composition of the soil is changing rapidly? Why?

What part of a plant are you eating when you consume each of the following? a. tomato b. apple c. spinach d. sweet potato e. black bean

In the angiosperm life cycle, which of the following processes is directly dependent on meiosis? a. production of gametophytes b. production of gametes c. production of spores d. all of the above

In angiosperms, each pollen grain produces two sperm. What do these sperm do? a. Each one fertilizes a separate egg cell. b. One fertilizes an egg, and the other fertilizes the fruit. c. One fertilizes an egg, and the other is kept in reserve. d. One fertilizes an egg, and the other fertilizes a cell that develops into stored food.

Which of the following is closest to the center of a woody stem? Which is farthest from the center? a. cork cambium b. primary xylem c. primary phloem d. secondary xylem

During a recent ice storm, many old trees were snapped by the weight of the ice. A botanist in the area would like to analyze the remains of the trees and determine how old they were. Describe a procedure that could be used to determine the approximate age of the trees. Explain the basis of this method in terms of plant tissue growth.

Interpreting Data Botanists observed that the number of teeth along the edges of red maple (Acer rubrum) leaves varies depending on where the tree grows. The botanists wondered whether these differences were due to climate. To find out, red maple seeds were collected from four sites (from north to south, Ontario, Pennsylvania, South Carolina, and Florida) and grown in two sites (Rhode Island and Florida). After a few years, leaves were collected, and the average number of teeth per leaf area were calculated: Number of teeth per cm2 of leaf area Site of origin Grown in RI Grown in FL Ontario 3.9 3.2 PA 3.0 3.5 SC 2.3 1.9 FL 2.1 0.9 Based on these data, does the number of teeth vary from north to south? Do the data suggest that these differences are due to climate or genetic differences?

Cloning is a fiercely debated topic in our country. Most of the ethical debates concerning cloning center on the cloning of animals. There is not much talk about the cloning of plants. Do you have the same opinion about cloning plants and animals? Why or why not? Do you think that they should be similarly regulated? What unique problems might each present?

When buying coffee, many consumers will pay more for coffee that is Fair Trade Certified because they believe that doing so will help family farmers in developing nations. A Fair Trade label means that the coffee was grown and harvested in accordance with a set of standards overseen by an independent nongovernmental regulatory agency. There are different certificates with different standards, but in general the Fair Trade Certified designation is meant to ensure that the coffee was grown by farmers in a cooperative that avoids child labor, does not use certain herbicides and pesticides, and is paid at least a fair minimum price for the product. Do these seem like worthwhile criteria to you? Would you be willing to pay more for coffee that meets these standards? How much more10% more? Double? If you do pay a premium for such coffee, do you think you can be reasonably sure that it accomplishes the Fair Trade goals?
