The experiment was done by the researchers to see the growth of plants with wider girth in warmer areas in Siberian pines ( Pinus sibirica ) in Tarbagatay pass region in Mongolia. They estimated that the growth of trees is reverse in cooler areas. It was assumed that with the increasing temperature, trees are getting longer and girth is becoming wider. The graphical data was prepared by taking account of the ring widths of the plants and years of growth. The conclusion has to be inferred from the experiment on the basis of the graphical data. Introduction: The study of growth rings or annual growth rings that are present in the secondary root xylem is called herbchronology. These rings are mostly present in the perennial herbaceous plants. The annual growth rings are counted and it gives a rough idea about the age of the perennial plant.

If New York experiences drought conditions during April, May, and June 2022, how would you expect local tree rings to differ compared to rings made in 2021 (which had normal rainfall)? Early wood cells would be larger in 2022, creating thicker rings Late wood cells would be larger in 2022, creating thicker rings Early wood cells would be smaller in 2022, creating thinner rings Late wood cells would be smaller in 2022, creating thinner rings Rings would be similar both years as water amount has little effect during spring and early summer

Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.Unit 8 DQ Question: Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? (Editor’s note: addressing this question will provide needed background information to the ‘Introduction’ of your paper).
