PHOTOSYNTHESIS

Hey guys today we got a stamp for 67-68 in our UP for those of you who were sick. After that we started talking about Photosynthesis and the different cycles. Then started a lab on leaf pigments. The notes are...

Photosynthesis Overview

• reactants: co2 h2o light and energy
• Products: o2 c6h12o6
• Two reactions

-light reaction

-Calvin cycle

Chloroplast Structures

• Thylakoids - sacs contain chlorophyll
• Granum - stacks of Thylakoids
• Stroma - open space and where Calvin cycle occurs

After the notes with finished a lab we had started called the pigment lab. i cant get the pictures uploaded but it was a cool lab. What we did was take 2 leaves, a spinach leaf and red leaf and used a coin to crush and press pigment onto a Chromatography paper After that we took the paper rolled in, stapled it, and dropped it into a solution for 10 minutes. When taking it out we saw an array of colors separated on the paper. These colors were the pigments found in the plant. In the paper there was 2 greens, 2 yellows, and a red. Whereas in the spinach leaf we saw only 2 greens and 2 yellows. This shows us that even though you may only see red or green, there can still be many many more pigments. That's why even though the red leaf is red there is still chlorophyll to carry out photosynthesis.

homework:

• finish lab analysis questions
• Do notes on 8.2 and 8.3 or complete Up pages 81-85
• Work on national park paper

Fridays Class

Today in class we went down to the lab to work on our National Parks paper. We also went over how do do a correct PowerPoint...

• No bright colors
• Font should be readable
• Not to much info on a page (In communications we leard to only have 5 pionts with 5 words)
• make sure colors dont blend with words
• don't make things to busy on the page
• and.....DONT OVER LOAD ON THE ANIMAL SLIDES, STICK TO PLANTS

the homework is;

• finish National Parks paper 3/23
• Read pages 643 and 664-666
