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.
