Hey guys!....

For today we were supposed to go to the IMC and research on our national park projects. But we didn't because the network was down. So we had a change of plans....

Today our Plant of the Day was the Sensitive Plant also known as the Mimosa pudica. It's native to Brazil so it probably will die before we see it flowers bloom.

We also went over the National Park Project. Remember to have 3 different species/kingdoms of plants. Also, please don't say any words that you can't pronounce. For example, you don't have to say the plants scientific name.

We also took some notes about the plant prequiz.

• The Plant kingdom rose from the Protista kingdom
• Plants need Gas Exchange. --> For Photosynthesis and Cellular Respiration
• Plants need Sunlight
• They need Waters
• They also need minerals
• Also a true water-conducting tissue are actually vascular tissue. When you have this kind of tissue the organism is tall or grows bigger. For example, big trees are big because they have this tissue. So the water they get from their roots are carried all the way to the leaves on top of the tree
• Some problems plants may have faced was that the sun might dry them out because they were used to being surrounded by water.
• Another problem is reproduction --> Spores would dry out.
• Seeds are embryos, which becomes the new plant, they store food and protects them from drying out

Lastly, we did a lab. It's Lab 25 from our Bear lab book. Because we didn't have a lot of time we only had time to draw our pictures. We were to draw in a cross section of leaf from a microscope at high power. We also had to label it. The next picture was a picture of a Wandering Jew Leaf. We also had to label a couple of things about it.

Today's homework:

• Finish the Leaf lab
• Work on your national park research (UP 9-14)
• Review section 8.1 with UP 79-80 due Wednesday
