Connective Tissue

Connective tissue is tissue that connects, supports or separates other tissues. They tend to have very few cells. An ear is made up of connective tissue.

Xylem

Xylem is the vascular tissue in plants that conducts water and nutrients upward from the root.

Phloem

Phloem is the vascular tissue in plants that conducts sugars downward from the leaves. Phloem can be found beneath bark.

Epithelial Tissue

Epithelial tissue is the membranous tissue that covers the internal organs of the body. Skin is an example of epithelial tissue.

Scavenger Hunt


Lichen

Lichen is any of numerous complex plantlike organisms made up of an alga and a fungus growing in symbiotic association on a solid surface, like this tree.

Gymnosperm Leaf

Gymnosperm leaves are leaves that can produce seeds in cone-like structures.

Modified Stem of a Plant

A modified stem of a plant is a specialized type of stem which can perform tasks that a normal stem cannot but can still perform the basics of a normal stem. Having thorns on a stem are an example of a stem being modified in order to increase its chances of survival.  The thorns on these stems protects the plant from being attacked by animals.

Modified Leaf of a Plant

A modified leaf of a plant is a leaf that performs additional functions other than the traditional functions like photosynthesis and transpiration.  The special tasks often force the plants to change the structure of their leaves to perform them this is why these leaves are oddly shaped.

Cuticle Layer of a Plant

The cuticles of a plant are a protective waxy covering the leaves that helps prevent desiccation which is the process of plants losing water to the air.

The Hot Zone: Part 2

Well I think that the book is still pretty good so far. I think that the fact that the author made it so detailed is what keeps me interested in reading it because otherwise it might of started to get boring. I like how the monkeys are now a bigger part of the book now and it shows how it wasn't just humans who were infected with this virus. The story is starting to move a little faster now, which is good, but there are a lot more characters being introduced so you have to pay a little more attention or it gets a little confusing. I'm curious to find out what is going to happen to the people who inhaled the virus, are they going to die too?

5 scavenger hunt pictures (Epithelial Tissue, Gymnospern Leaves, CAM, Xylem, Hydrophilic)

CAM: Carbon dioxide is taken in at night so the stomata stays closed during the day to keep the water in and the plant can survive longer with out a water source.

Epithelial Tissue: Most outer layer that protects muscles and organs from damage.

Gymnosperm Leaves: Pine needles are seed producing

Hydrophilic: Hydrogen bonding causes the water to stick together in clumps.

Xylem: Tree rings are the transport tissue if the tree, or it's xylem.

Autotroph

An autotroph is pretty much any plant that uses photosynthesis which means that it makes its own food. So this tree is an autotroph the same as any other tree.

Segmented body

A segmented body is when the body is divided to segments were the segments piggyback on one another, like a series of cars in a train. Grasshoppers have segmented bodies.  

Ectotherm

This toad is an example of an ectotherm because it is an animal that is dependent on external sources of body heat.

Ethylene

Strawberries are an example of Ethylene because it is a colorless flammable gas with sweet and musty odor when pure.

Heterotroph

My dog is an example of a heterotroph because he consumes to create energy with the food we give him, he doesn't make his own food.

Fronds


This would be an example of fronds because fronds are large divided leaves

Hot Zone Part 1

Sorry Im sooo behind. I get lazy during summer, but better late than never! :p

This book isnt something I would have picked out myself to read but its intresting although I find myself saying "TMI" pretty often. However I've learned that there are many different viruses that people have to be aware of in other places that we dont deal with so much here in the United States. The Ebola Zaire, for example, is so deadly it almost seems unreal or made up. Its also pretty cool how UV light breaks apart viruses, I didnt know that. I dont have questions to often when it comes to books like these, theyre pretty informational already for me to want to store more information in my head!

Dominant vs. Recessive phenotype


Dominant vs. Recessive phenotype- Dominance in genetics is a relationship 
between two variant forms of single genes, in which one is more likely 
to appear. for example my brown eyes are dominant over my sisters
recessive green eyes. 

Cellular Respiration


Cellular Respiration- Is the set of the metabolic reactions and 
processes that take place in the cells of organisms to convert biochemical 
energy from nutrients into ATP and then release waste products. 
This tree is an example of cellular respiration.

Parasitism


Parasitism- A type of non mutual relationship between organisms of 
different species where one organism, the parasite, benefits at
 the expense of the other, the host. 
So the mold is benefitting and the pepper is no longer edible. 

Epithelial tissue


Epithelial Tissue- Membranous tissue covering internal 
organs and other internal surfaces of the body, such as skin.

Unicellular organism


Unicellular Organism- An organism that consists of only one cell. 
For example yeast is unicellular.

Fermentation


Fermentation- A change brought about by a ferment, 
as yeast enzymes convert grape sugar into ethyl alcohol. 
Wine is a perfect example of fermentation. 

C4 Plant


C4 Plant- Plants that are able to more efficiently 
fix carbon in only certain conditions. Corn on the cob is an example

Ethylene


Ethylene- A colorless gas making a sweet taste. 
Grapes contain ethylene.


Genetically modified organism


Genetically modified organism- Is an organism whose
 genetic material has been altered using genetic 
engineering techniques.

Mycelium


Mycelium- The vegetative body of fungi that is threadlike.
 Just like the particles in mushrooms.

Epithelial Tissue

 Epithelial tissue is the outermost layer that guards different muscles and organs to keep them safe from damage.

The Hot Zone: Part Two

SO the second part to this book was much more interesting than the first. I have to admit that the first part went a little slow for me, but it's getting better. I did notice that this book is very gruesome as well! I didn't know that monkeys had SO many human traits either. I am still a little confused about who is who because there are so many characters. I don't really understand why not all get sick from the virus if it is in the air. it just doesn't make sense! The second part was much more interesting than the first. BY FAR.

Long-Day Plant

 A long-day plant is a plant that needs needs hours and hours of exposure to sunlight to produce flowers.

Heterotroph

 A heterotroph is an organism that cannot produce its own food and relies on other organisms to live.

Pollen

 Pollen is the way that plants reproduce. Pollen is spread by the wind from flower to flower.

Pollinator



 A pollinator is a plant that produces pollen which contains seeds to reproduce with other plants since plants have no way of physically moving they rely on the wind.


Scavenger Hunt

 Modified root of a plant- this is the cut down version of a carrot which is a root but it is also stores carbohydrates which makes it a modified root.
 Ovary- It is the base portion for the female part of the flower which contain ovules that develop into seeds when fertilized.
 Endotherm- a warm blooded creature that maintain a constant body heat not depending on the environment they live in.
 enzyme- in the fermenting process of wine there are chemical reactions which are regulated by enzymes.

C3 plant- this rice is an example of the occurrence where CO2 is turned into an organic compound.

Gymnosperm leaf/adaptation of a plant

Pine needles are an example of a gymnosperm leaves because they are seed producing. They are also an adptation because the shape of the pine needle enables it to retain water and tolerate dryer, colder conditions better.

Eukaryote

Deer are an example of Eukaryotes because the are multicellular organisms whose cells contain complex structures within membranes.

3rd Scavenger Hunt Post

1. Mating Behavior



These spiders are exhibiting mating behavior within their web.

2. Exoskeleton






This is the shed exoskeleton of a spider that I happened to pick up along with my water bottle. Spiders shed their exoskeletons as they grow larger.


3. Ectotherm






This frog is an ectotherm because its body temperature is dependent on its environment.


4. Meristem


This branch once contained Meristem tissue, which is the tissue that contains undifferentiated cells that eventually form xylem and phloem, which are vital to the plants health.






5. Pollinator



This odd looking bee is a pollinator that transports pollen from the male anthers of a flower to the female stigma of a flower for reproduction.



4th Scavenger Hunt Post

1. Animal that has a segmented body






This spider is an organism that has a segmented body.


2. Phloem


The phloem in this plant is living tissue that carries vital nutrients throughout the plant to sustain life.


3. Parenchyma Cells



The root cortex parenchyma cells in this plant serve vital plant functions such as storing of starch, protein, fats, oils and water.



4. Vascular Cambium



The vascular cambium of a plant consists of cells that are partly specialized for the transport tissues within the plant.




5. Gibberellins



Gibberellins are plant hormones that regulate growth and influence multiple developmental processes, specifically in this case budding of flowers.
