Venus Flytrap Video


I always knew that venus flytraps are one of the most interesting plants of all time. Except I never understood HOW exactly they are able to sense prey on them. I also never figured out what happens to the prey once it's been "ingested."
However, this video plus some addition research helped me figure this out.
Basically, the prey lands on the sensitive surface of the open trap. If the prey isn't able escape, it continues to sort of "stimulate" the inside surface of the lobes, and this causes a response that forces the edges of the lobes to close together and that eventually seals the trap and forms a 'stomach' where digestion happens. Digestion is initiated by enzymes by the glands in the lobes. Digestion takes about ten days, and after that the prey is turned into chitin (nitrogen-containing polysaccharide; it helps build the cell wall). The trap reopens afterwards, and is ready to consume the next victim.
Tooooooo cooooooooooool ahhhhhhhh.

Interesting Plant - Strangler Fig

The strangler fig is probably the coolest thing ever.

It kills.
:O

There are many different species of Strangler Fig, but they all are basically the same thing. They're strange because they will grow up and down. Down so they can choke the living tree of all the nutrients, and up for sunlight. They often outlive the host tree by years, sometimes forming hollow cores that house the "spirit" of the old tree.
These "figs" can live up to thousands of years.

Acorns vs Pine cones

Acorns grow on oak trees and are the seeds for them, while pinecones contain seeds and are from pine trees. Acorns fall to the ground and are eaten by animals to spread their seed. Pinecone seeds fall to the ground and are dispersed by the wind. The trees that acorns grow on are deciduous whereas pine cones grow on coniferous trees. Acorns have one seed and pine cones have multiple.

Roots/Stems/Leaves pics+questions

We did not have time to label every part, but we did a few labels on each one.

Roots: 
1) absorption of water/nutrients
2) xylem and phloem 


Stems:
1) transports water/nutrients from place to place
2) plant with true woody stems contains wood and do not die off every year, while herbaceous plants do not contain wood and die back to their roots in cold periods


1) they help in photosynthesis and storage of nutrients
2) carbon dioxide is converted to glucose
3) The stomata are pores in leaves. They are responsibe for gas exchange. Carbon dioxide enters through the stomata. Oxygen leaves through the stomata. Important for humans because it lets us breathe in oxygen

Mid-Term Evaluation

PART 1) 


1) Classification and Taxonomy

http://raajvirkbiology.blogspot.ca/2013_09_01_archive.html
























I linked the Classification Project, the test, and three other assignments we did in class which I think wrap up the classification/taxonomy topics. During this section, I learned about the different kingdoms, and about how all organisms are categorized. I think my marks reflect my good understanding of this topic.

Basics of what I learned:

- the kingdoms (plantae, animilia, protista, fungi, eubacteria, archaebacteria)
- differences between prokaryotic and eukaryotic cells
- rules of classification (kingdom, phylum, class, order, family, genus, species)


2) Evolution

http://raajvirkbiology.blogspot.ca/2013/10/answer-why-are-owls-able-to-spin-their.html

























For this section, I linked a blogpost about what I learned about owls and their adaptive technique due to evolution. Also, I chose the graphing assignments we did which show variation and DNA replication. Also, the different types of natural selection. Lastly, I included the project that took ages to do; the one about the extinct/alive animal that evolved into so many different species! I think that these posts show my good understanding about evolution and DNA replication.
ACED IT!

Basics of what I learned:

- what is DNA, what it is made of (sugar phosphate), structure (double helix, adenine, thymine, cytosine, guanine) and why it is important to evolution
- what causes evolution (changes in environment, etc.)
- different types of evolution (stabilizing, disrupting, directional)
- natural selection, and how it allows evolution to occur
- examples of evolution in nature, for ex. peppered moths


3) Viruses

http://raajvirkbiology.blogspot.ca/2013/10/part-1-1-structure-is-from-either.html


I picked the link to the mini project we had to do about viruses, what they are, how they come into the body, how to prevent them, and an example of a virus. After the project, I had a clear grasp on viruses. Because of that, I got a perfect score on the virus test, which I also posted.

Basics of what I learned:

- reasons for why viruses could be living or non living
- the lysogenic cycle where the virus in dormant and the lytic cycle where the virus attacks cells
- prevention methods from viruses and how vaccines work
- characteristics of a virus

4) Bacteria

http://raajvirkbiology.blogspot.ca/2013/11/all-you-need-to-know-about-bacteria.html

http://raajvirkbiology.blogspot.ca/2013/10/our-bacteria-shapestypes-asad-brittany.html

http://raajvirkbiology.blogspot.ca/2013/10/blog-post.html





I decided to link my blog posts about the assignment where I learned all the parts/functions of bacteria, types and shapes of bacteria, and the labs I did about bacteria growth. I also included some important notes on bacteria which really helped me understand the parts and how bacteria looks, and also the differences between bacteria and viruses. I chose those notes to post because they helped get a perfect score on the quiz/test and because I think that they contained important information.

Basics of what I learned:

- bacteria is living
- what separates bacteria from viruses
- characteristics of bacteria and parts of bacteria
- three different shapes and the arrangement (staphlo or strepto/ spirrilum, bacillum, or coccus)


5) Protists





I chose the picture the amoeba we found in the pond water. That was my favourite thing to look at under the microscope! It was actually moving which I found really interesting. I also posted the notes that helped me understand the characteristics of protists and understand the difference between bacteria and protists, which I had some trouble with in the beginning. Lastly, I put up a picture of the quiz, which I aced! This shows my understanding of what protists are.

Basics of what I learned:

- how some protists are heterotrophic and some are autotrophic and what the differences are
- how diverse protists can be
- how they are mostly aquatic
- how protists use binary fission to reproduce and use sexual conjugation


PART 2


In this class, I think I've done my part of participating, doing the work, showing respect and actually learning something! Usually, for most classes, kids (along with me) participate etc. because it helps you get a good grade. However, it's been kind of different for me in this class. I participate, listen, and do the work because I actually want to! I think it's kind of fascinating when you think about the broad perspective of biology. It kind of gives you a whole different view on things. Everything around you seems so much bigger than it really is, and when you look at the leaves and plants outside, you think about how they are actually a huge part in making this whole cycle of life possible! Of course I'm not perfect, I think I may have an assignment that I didn't do too well on or missed. However, the time I put in to study and actually question "why" reflects on my test marks. Although I think that my in class work has been good because I feel like I always ask questions and want to learn, I think it's important that you reflect your learning outside of class, too, which is what I think I've been doing. Maybe not in huge ways like hunting down a new and undiscovered organism, but just talking about what I learned in class to friends, showing my mom my blog and videos, and telling my dad about tardigrades (which blew his mind) is also, in my opinion, a good reflection of learning. I think my mark in this class based off of participation, will to learn, and perfect test scores would be a good way of accumulating a mark. I also think that how I reflect what I learn in class outside of class, too, should come into account. I think I deserve a 95% in this class. So far, I'm getting about 100 in each class. But I think I do have some improving to do if I think I'd want to give myself 100 in this class. I think I need to improve on socializing less and putting down my phone! I have been trying though, and I guess it it possible to live without my phone. Who woulda thought.

Overall though, I believe I deserve a 95% in this course, so far. :)

Celebrity Organism

Agra schwarzeneggeri 

A beetle found in Costa Rica was found in 2002. The awesome part about this is that it's named after Arnold Schwarzenegger! The reason for this is because the hugely developed bicep-like middle portion makes the beetle's shape look weirdly similar to the physique of Arnold Schwarzenegger.
What the heck HAHAH

All You Need to Know About Bacteria

Note: Did not label for some stupid reason before taking the picture, so bear with me.

- salmon coloured space in the middle: CYTOPLASM = contains content
- the dots in the cytoplasm: RIBOSOMES = make protein
- salmon coloured sticks poking out: PILI = exchanges genetic material
- first layer: CAPSULE
- second layer: CALL WALL
- third layer: PLASMA MEMBRANE
- bean looking thing in the middle: ENDOSPORE = used for survival of bacteria
- swirly thing: DNA
- tail: FLAGELLUM = used for movement


Bacteria comes in three shapes:

- a spiral: SPIRILLUM 
- a circle: COCCUS       
 - a rod: BACILLUM       

There are two arrangements:

- clumped together: STAPHLO
- in a chain: STREPTO             



This is an example of: Staphlococcus



This is an example of: Spirillum



This is an example of: Streptobacillum
