Artifact collection PART 2


.::Carbohydrate Fibrous::.
Carbohydrates are made up of mostly cellulose. They help move starch through the body, along with that, they allow the body to extract their nutritional elemnts. This picture shows a cucumber as an example of that
 
 
 
 
 
 
 
 
.::Herbaceous Stem::.
Herbaceous Stems are stems that have little or no woody tissue. (Typically greenish) As shown on the stem on and around this flower.










.::Thorn of a plant::.
The thorn of a plant are the sharp prickles on the stem of some plants. This photo of a rose shows the prickles running down the stem.










.::Cambium::.
Cambium is a layer of material in a plant or tree that is responsible for dividing cells that make sure there is growth for the plant. This photo of a tree trunk show an example of the layer of material.












.::Phloem::.
Phloem is a pipepline tissue structure that carries water and food from the roots of the plant to the leaves. This tree shows a good example of phloem because the structure starts from the roots of the tree to the very top leaves.




 
 
 
 
 
 
 
 
.::Xylem::.
Xylem is a pipeline tissue that carries water and minerals from the roots of the plant to the leaves. This tree, like in phloem, shows a good example of xylem because the structure starts from the roots of the tree to the very top leaves.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
.::Arthropod::.
Arthropods are invertebrates with external skeletons, segmented bodies, and jointed appendages. This spider shows an example of all three features.
 
 
 
 
 
 
 
 
 
 
 
 
 
.::Vascular Plant Tissue::.
This plant tissue consists of both the Phloem and Xylem. The two pipelines run close by from the roots to leaves. It provides channels to transport water and nutrients. Again, like both phloem and xylem, this tree shows an example of the roots to leaves of the tree.
 
 
 
 
 
 
 
.::Radical Symmetry::.
Radical symmetry is symmetry in which something can be divided into two identical halves by a line passing through a centeral point of axis of any angle. This dandilion shows an example of radical symmetry because of its symetrical structure.
 
 
 
 
 
 
 
 
.::Lepidoptera::.
Lepidoptera is a classified catagory for insects catagorized by wings with overtapping scales.
This butterfly shows an example of the structures used to catagorize.










 .::Exoskeleton::.
An exoskeleton is an external skeleton that supports and protects the body of some animals/insects. This roach shows an example because of its exoskeleton structure.














.::Epithelial Tissue::.
Epithelial tissue covers the whole surface of the body. This tissue is made up of cells closely packed together in one or more layer. An example i used is the human arm because it is covered in skin, which is what epithelial tissue is; a layer of tissue (cells closely packed).

 



 
 
 
 
 
 
 
 
.::Insect::.
Insects are creatures with three pairs of legs, a body segmented into head, thorax, and abdomen. Which i represented through a roach. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  .::Cellulose::.
Cellulose is an organic compound which consists of multiple chains of glucose molecules strung together. This organic compound is found in most paper, which is what i used to represent it with.
 
 
 
 
 
 
 
 
 
.::Endosperm::.
Endosperms are nutrious seeds found in the seeds of flowering plants. An example of an endosperm is this portion of corn.
 
 
 
 
 
 
 
 
 
 
.::Amniotic Egg::.
This kind of egg is produced by reptiles, birds, and such. The embryo developes inside an amnion.
 









.::Amylase::.
Amylase is an enxyme that breaks starch down into sugar. (Saliva) The digestion process starts there. Foods that contain a lot of starch but little sugar taste slightly sweet as chewed because amylase turns some of the starch into sugar in the mouth. To represent amylase i have taken a picture of tha human mouth to show where saliva is found and where the taste changes due to the breaking down from the enzyme.

.::Endotherm::.

An animal whos body temprature does not change with its surrounding environment. Which i used to represent through the human body, because our body temprature remains constant.















.::Ectotherm::.
Animals who's body temprature varries with the temprature of its surroundings, and do not produce much internal heat. Which i used to represent with these fish. (Ms.Washington, at the time I saw this I didn't have my little object with me, but I did take this picture on my phone.)














.::Commensalisim::.
Commensalisim is a symbiotic relationship where one organisim benefits and the other is neither harmed nor benefited. To represent this relationship I used a squirrel in a tree. This shows commensalisim because the squirrel gets shelter from the tree and also may get food, nuts and such. Nothin happens to the tree though.
