Lesson Worksheet: Photosynthesis Science

In this worksheet we will practice outlining the process of photosynthesis, stating where it occurs, and describing how a plant obtains the materials that it needs.

The figure shows a cross section of a plant root.

What is the function (job) of the xylem tissue shown in the figure?

  • AIt transports minerals made in photosynthesis down from the leaf.
  • BIt transports carbon dioxide up to the leaf to use in photosynthesis.
  • CIt transports glucose made in photosynthesis down from the leaf.
