Reinforcement for the Quiz!

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

Photosynthesis

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 to know when learning about photosynthesis such as autotrophs, heterotrophs, pigments, chlorophyll, and stomata.

Tomorrow, we will start to dive deeper into the the process of photosynthesis.  The reading for tonight 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 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.

Cell Division- Mitosis

Here is a great image of mitosis.  This is much like our text book but do not worry about the "Prometaphase."

Mitosis is the process of cell division for eukaryotic cells found in multicellular organisms.  All cells come from existing cells and mitosis is how most cells divide. The only eukaryotic cells which do not divide by mitosis are sex cells a.k.a. gametes a.k.a sperm and egg cells. 

Here are some videos that introduce cell division- mitosis.




Here is a video that links cell division -mitosis and cancer.
