Lesson 6

How are all these things interacting together in this part of the plant?

Lesson Objectives...

A Plan and carry out an investigation to support a claim about how the inputs to a plant are related to what the plant cell can produce from chemical reactions in the chloroplasts (outputs).
Engage in argument from evidence about what plants need to make food molecules using evidence from the computer simulation and scientific reasoning to support an explanation for why decreasing the amount of water, carbon dioxide, light, or chloroplasts (cause) in a plant cell decreases the amount of sugar and oxygen it produces (effect).

Slide Presentation for Lesson 6...

This is the slide presentation used by your teachers when navigating through Lesson 6.

Conduct investigation A using the procedure. Record your observations and results in your science notebook.

Conduct investigation B using the procedure. Record your results in your science notebook.

Water and carbon dioxide molecules, along with light, interact in chloroplasts in plant cells, where they are used to make oxygen and sugar molecules. Each of these inputs is needed to produce these outputs.
In this process, molecules of water and carbon dioxide are broken apart and the atoms that make them up (carbon, hydrogen, and oxygen) are rearranged to form new substances.
As more inputs are provided to the plant cell, the more oxygen and sugar are produced.
