Cell Energy Assessment Essential Questions

1. What is photosynthesis? Explain in your own words.

2. What are the raw materials and products for photosynthesis? Where do they all come from? What are they used for?

3. What is the difference between heterotrophs and autotrophs? Give examples of each.

4. What are the two stages of photosynthesis?

5. Where does the energy come to drive the process of photosynthesis?

6. What is cellular respiration? Explain in your own words.

7. What are the raw materials and products for cellular respiration? Where do they all come from? What are they used for?

8. What are the two stages of cellular respiration?

9. How do cellular respiration and fermentation differ? Think energy and oxygen.

10. What are the two types of fermentation.

11. What is the stoma? Explain its structure and function in a plant.

12. What does it mean to say that photosynthesis and cellular respiration are cyclical process? How do they combine to create energy for organisms?

Putting it all together! Cyclical Processes

Using these two images think about how the processes of cellular respiration and photosynthesis are cyclical; that is how one connects to the other.

Comparing Photosynthesis and Respiration

This is a great review for Thursday's Quiz!

Here is a helpful video on the processes of photosynthesis and cellular respiration:

Here is a video on the processes of photosynthesis. Most of the stuff is "Want to know" rather than "Need to know". If you feel like you've got everything down and want to see the next level check it out! Hank Green is cool, but why does everyone talk so fast?

Be sure to spend some quality, focused time studying each night!

Cellular Respiration

Today in class, we will begin to shift our focus from photosynthesis to the process in which energy is made, cellular respiration. Let's start by reviewing the section in the Science Explorer text on the topic.

Cellular Processes - Energy

Photosynthesis & Respiration Introduction

Today in science we introduced our new unit on Photosynthesis. Photosynthesis is the process by which a cell captures energy in sunlight and uses it to make its own food (a type of sugar called glucose).

As a class we focused on a few key terms from the GUIDED NOTE SHEET to know when learning about photosynthesis such as autotrophs, heterotrophs, pigments, chlorophyll, and stomata.

The reading today will help reinforce our new understanding of how organisms get energy. The reading will also introduce the two stages of photosynthesis.

Here is the link for the reading from our Science Explorer text.
Here also is a Question Sheet that goes with the Text.

Here is a great three-minute video from Discovery's "Greatest Scientific Discovery" series that will introduce the experiments that enabled Priestly and Ingenhousz to "discover" photosynthesis.

Introduction to Cellular Energy

Today we are Introducing Cellular Energy:

MS-LS1-6.

Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

MS-LS1-7.

Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
