SBI 3C: Culminating Task – U1 Cellular Biology

Explanation:

Cell Theory:

1) All living things are made up of cells

2) Cells are the basic units of structure and function in living things.

3) Living cells come only from other living cells.

The key point of Cellular Biology that I chose was Cell Theory. Cell Theory is really important because it provides one of the greatest connected theories in biology: one that says in spite of all the vast diversity of organisms, they are all united at a very primary level, namely the presence of cells. But at the same time it’s important based around classification and arrangement of life. The knowledge I gained from learning about Cell Theory for real life application/situation is perhaps if you were considering becoming a Stem Cell donor or in need of a Stem Cell transplant, which is sometimes necessary if your bone marrow stops working and doesn’t produce enough healthy stem cells.

Websites:

Website 1) http:www.biologyreferences.com/GR-Hi/History-of-Biology-Cell-Theory-and-Cell-Structure.html

This website provides a history of Cell Theory and Cell Structure. It includes early observations throughout the 1600’s  leading into the 1700’s, the development of the Cell Theory, the reproduction and inheritance and lastly the modern advances. I thought this website was a reliable sources because it provides a clear outline, gives dates, names and all within timely order. This website doesn’t give good figures/photo or analogies to help understand the concept but all in all is very organized and very informing.

Website 2) http://www.biotechlearn.org.nz/themes/cell_biology_and_genetocs/video_clips/cell_theoty_why_is_it_importmat_v0202

This website provides a video featuring Sir Paul Nurse, who is a British geneticist, cell biologist and Nobel prize winner in Physiology or Medicine with the discoveries regarding cell cycle regulations. He gives a 1 minute, 11 second lecture explaining why cell theoty is important. I think this is very reliable website based on the background of the speaker, he provides pictures throughout the speech. As well he gives a clear understanding in the importance of cell theory in five major points.

Rough notes:

-Microbiology typically includes the study of the immune system, or immunology.

-The immune system is a network of cells, tissues, and organs that work together to defend the body against attacks by “foreign” invaders

-These are primarily microbes—tiny organisms such as bacteria, parasites, and fungi that can cause infections.

-immune system’s job to keep them out or, failing that, to seek out and destroy them.

-The combination of new technology and expanded genetic information will no doubt reveal even more about how the body protects itself from disease.

A real life example

– a cut in your skin which bacteria can enter the blood stream. These bacteria let off chemical signals that alert certain kinds of white blood cells called phaocyte. A phaocyte surrounds pathogenes by sending out extensions of its cell body which envelups the invadors once inside the phaocyte the pathogenes are dissolved by chemicals.

A couple websites I used to research further on the immune system were

– kidshealth.org – which was a great source for reserach. i learned a lot about the defenses, types and function.

-and various youtube videos, gathering helpful pieces of information throughout

-national institute of allergy and infectious deiseases.

SBI 3C: Culminating Task – U3 Genetics

Characters:

Identical Twin Daughters- Kayden & Korey

Mother – Brenda

Father – James

Kayden & Korey “Mommy. Daddy. How come we look the exact same?”

Mother “Well girls. When mommy’s and daddy’s decide to have babies, some are lucky enough to have a single egg that splits into two separate embryos.”

Korey “What’s an em..bry..a?”

Brenda *LAUGHS* “Embryo, darling. It’s an unborn baby before all your organs inside you are made.”

*The twins giggle..*

Korey “Ew, gross!”

Kayden “But how if we are the same egg, how come we aren’t the same?”

James “Well because of your DNA. You share the same DNA but it’s not identical.”

Brenda “Kind of like when you cut an apple in half. The two halves may not look the exact same.”

Kayden “What’s DNA?”

James “It’s actually a really big word – deoxyribonucleic acid. It’s what makes you who you are.”

Kayden “Dee..oh..ribs.nucleur..acid?”

James *LAUGHS* “Close enough!”

Brenda “For example, your eye colour is blue because you got it from your dad. That’s called inheriting a trait.”

Korey “Well how do we know what trait we are going to get?”

James “Based on your recessive or dominate traits. Which means: what traits mommy has and what I have.”

Korey “I guess that makes sense.”

Brenda “Maybe next week we can go to the library and get some books about twins!”

Kayden “Yeah! That would be cool.”

Korey “Yeah! And maybe we could use the computers there too.”

James “Sounds like a good idea to me.”
