You are studying an interaction between a plant, its pollinators (bees), its seed dispersers (ants), and an endoparasite of its seed dispersing ants (a wasp). Based on this information, the wasp endoparasite is: A competitor of the plant. A mutualist of the plant. A commensal of the plant. An antagonist of the plant.

Q- You are studying the growth of a particular species of plant and you notice that as time passes, your plants’ root: shoot ratios consistently decrease. In this system, is the limiting resource an above-ground resource, or a below-ground (soil) resource? A- Above ground; because the plants are allocating more resources to root growth B- Above ground; because the plants are allocating more resources to shoot growth C- Below ground; because the plants are allocating more resources to root growth D- Below ground; because the plants are allocating more resources to shoot growth

Course: Botany In stable populations, ones that are neither increasing nor decreasing in abundance (e.g., there are a million trees now and there will be a million trees a thousand years from now), about how many of a plant’s seeds survive and grow to adulthood, being able to replace it when it dies? If during the plant’s lifetime it produces 100,000 seeds, how many do not survive, do not grow, and cannot replace it when it dies. (Hint: Do not think of humans, as we are an increasing population, not a stable one. Almost all our children survive, but that is not true of any other species.) Answer and explain briefly.

emphasized how plastic and adaptable plants are in their environment.  Write an essay touching on this concept.   The first paragraph should be broad and discuss why plants must be more adaptable to their environment compared to other organisms, such as animals.  Discuss if adaptation is or is not genetically determined and/or heritable.   The second paragraph should provide a specific examples of how plants have adapted to stress.  This portion needs to be in depth, and discuss both an abiotic and biotic stress.

Doug Schemske is a biologist who studies plants from around the world.  Doug and his research team carry out experiments with the plant species Mouse-ear Cress, or Arabidopsis thaliana. They like this species because it is easy to grow in both the lab and field. Arabidopsis is very small and lives for just one year. It grows across most of the globe and in a wide range of latitudes and climates. Arabidopsis is also able to pollinate itself and produce many seeds, making it possible for researchers to grow many individuals to use in their experiments.  Doug chose Arabidopsis populations in Scandinavia and the Mediterranean for his research on local adaptation because those two locations have very different climates. The populations may have adapted to have the highest survival and reproduction based on the climate of their home location.  To deal with sudden freezes and cold winters in Scandinavia, plants may have evolved freeze tolerance traits, which produces chemicals that act like…

Prepare a summary of this article without distorting the message it wanted to convey For farmers, pesticides save labor and generally provide a higher yield: they can mean the difference between saving a crop and losing it to disease. Some farmers, especially those who grow produce at a smaller scale, use pesticides sparingly. For example, fruit trees are susceptible to disease in northeastern regions, especially at the blossom stage. An apple or peach grower may spray their fruit trees with a fungicide once in the spring to ensure that the fruit sets, but use no further chemicals for the rest of the season. For many large row crop farmers, on the other hand, regular pesticide use is as much a part of farming as planting seeds. Spraying Roundup on a field of corn genetically engineered to withstand the chemical kills! the weeds without affecting the corn. In comparison to mechanically weeding hundreds or thousands of acres, using pesticides is a game-changer. Some farmers spray their…
