PBS Nova Web Quest

I watched a video on PBS Nova called Revealing the Origins of Life. I learned that life on earth probably started billions of years ago by a single celled organism. This organism was made up of Hydrogen, Oxygen, Carbon, and Nitrogen. It also started to form in a small pond where there was lots of sunlight.

I also watched a video called Evolution of Laughter. It explained that us humans start to laugh at the age of three months. Scientists say that the laugh evolved from four other monkeys. First the orangutan, then the gorilla, then the chimpanzee, then the bonobo, which then led to us. Scientist also say that the louder the you have, the more happy you are.

         The plant seeds are divided in to two groups called gymnosperms and angiosperms. Gymnosperms seeds are on the surface of the cone and Angiosperm are a layer under to protect the seeds. Angiosperm go through the process of pollination before reproduction and have stamens which on one end is the anther where pollen is made. The stigma then goes down the tube called the style of ovary. And the fertilization is during the process of pollination. A female flowers center contains long thin filaments and topped with oblong anthers combined to call stamen.  The anthers have 4 pollen sacs that produce pollen that are microscopic mother cells. Each sac will produce  sperm cells from mother cells and when ripe the anthers open releasing sticky pollen onto the stamen making seeds.

           This short video touched on the beginning factors of the tree of life. Starting with the basic recipe of RNA, which links all living things together. In other words, below the tree of life are the roots which is composed of the chemical bases of life. When these chemicals are combined in a certain fashion in the right environment you can create the bases of an RNA strand.

          Later, I was able to go in a completely different direction and watch a short film documenting the evolution of laughter. The film started out by explaining why human babies laugh? This question can be answered in one simple yet complex word and that is survival. Since newborns are so weak and defenseless they use laughter to help persuade parents that their cherubic appearance is no act. As the zoologist went deeper into the origins of laughter they were able to create an accurate timeline of laughter. This timeline consisted of orangutan, bonobo, and finally humans. However, the laughter of humans is a bit more complicated then the laughter of primates. For example, human laughter can act as a "glue" which connects one and other and has helped made us more successful as a species. Highlighting this factor is simple because it can be some up by looking at human interaction in a romantic perspective. For example, by husband and wife laughing they create a bond or trust which would allow them to reproduce and the population would therefor evolve.

Assignment #7 Anthers, Stigma, and Styles

Here is my yellow flower before I removed it from the broccoli stalks

A carpel is the ovule and seed producing reproductive organ in flowering plants, consisting of an ovary, a stigma, and usually a style. It may occur singly or as one of a group.

 This is the male reproductive part of a flower known as the stamen. The stam is the pollen-producing reproductive organ of a flower. Anthers are attached to the filament either at the base or in the middle portion.

The image above shows the female ovary that has been removed and is containing a minuscule ovule. The small egg shaped ball next to the stigma  is an unfertilized female gametes







































  

Blog Post #7: Dissection of a Flower pictures

Period 4 all had to dissect a flower to show the different parts of the reproductive system of a flower. Here is the flower that I dissected.

This is a close up view of the flower from under the microscope.

In this close up view, it is showing the male stamen of the flower. This produces pollen in order to be spread around the bees. This process creates more flowers.

These two pictures show the female carpel. This part of the flower holds the ovaries at the base of the flower. In order to reproduce it collects the pollen with a sticky substance contained in a tube like shape called the stigma.

Our Broccoli Flower from our school garden.

Here is the stamen of our broccoli stalk. The stamen is the male reproductive system. The stamen produces pollen rthat get released. This is how flowers reproduce. This why bees help flowers; they accidently pick up pollen and the next time they land on a flower with the female reproductive organ they fertilize it.

This is the carpel, the female reproductive organ. Pollen is released into the carpel. The sticky tip called the stigma collects the pollen and it releases into the tube of the carpel. Then it fertilizes the ovaries.

In this picture everything on the flower except the ovaries.

GATTACA Quote responce

"I got the better end of the deal. I only lent you my body, but you lent me your dreams."

Both Jerome and Vincent both saw themselves as useless, Vincent is an invalid and Jerome has no legs. Jerome and Vincent both are looking for away to save themselves from there problems, as soon as they met and started to corporate they went from useless to useful. Jerome helped Vincent to his dream to go on the space ship, and Vincent gave Jerome a reason to stay alive. At the end Jerome killed him self because he had no point to live, but he took his award as him being proud of himself with him. Vincent was able to go on his dream mission but as an invalid.

Quote Response From The Movie GATTACA

"If at first you don't succeed... try, try again"(Jerome).

I think what Jerome meant when he said this quote, that if a person fails at something. They should not give up, but keeping trying your best in order to achieve what you want to succeed. So keep trying, even if you fail.

Responding to Gattaca

"You want to know how I did it? This is how I did it, Anton. I never saved anything for the swim back." -Vincent

       When Vincent said this to Anton its ironic in a sense that he is referring to his life since GATTACA.  He is depicting his life under a false identity as a race with his brother. Vincent was determined to go all the way even if it meant he would not return. Anton was always destined to out do his brother, but when Vincent re-writes the statuesque and beats his brother, he is proving the flaws within genoism. By giving 100% in his in the race and in life he was able to accomplish all he set out to do.
