AP Bio Scavenger Hunt

I am going to use this photo for both "animal that has a segmented body" and "Insect".

1: I took this picture outside of the dorms I am staying at while desperately scrambling to take the picture of this ant, who was making it impossible to get a decent quality picture.As you can see, barely, the ant has a segmented body consisting of three main parts: the head, the thorax, and the abdomen. The head contains the jaws and the antennas on the ant, the abdomen contains the six legs that give the ant movement, and the thorax contains most of the important organs.

2: This picture also fulfills the insect term as an ant is classified as an insect. Ants are insects as classified by the taxonomic hierarchy. Ants are in the animal kingdom, the arthropod phylum, the insect class, hymenoptera order, and the Formicidae family.

3: Adaptation of a plant- This tree shows a phototropism. It is a positive reaction to the light that is showing over the building. In regular circumstances, the tree would grow straight upward, but because the light can only be seen over a certain height of the building, the auxin hormone caused the plant to bend towards the light. Therefore the plant shows adaptation to its surroundings by bending itself to attain a greater amount of sunlight.

4: Vascular Plant Tissue- I found this plant on the way to class at the Science and Engineering building at Rutgers for Governor's School. This picture is relevant because it can be used to show the vascular plant tissue on a plant. This is the tissue that conducts water and nutrients throughout the plant. It includes xylem, which conducts water, and phloem, which carries nutrients. The vascular tissue is present in the entire plant, moving from the roots to the leaves and back down to the roots. This tissue is imperative to the plant's survival.

5: Female Pine Cone-
I found this pine cone on the ground by the evergreens near my dorm. I feel that the pine cone is a female for a couple of reasons. Male pine cones tend to be found near the bottom of the tree while females tend to be found higher up. This pine cone is larger in size as females tend to be compared to the other smaller pine cones scattered around the tree. Therefore I came to the conclusion that this pine cone is likely to be female.

6: Stem- woody
I found this stem outside of the dorms on an evergreen tree. I chose this picture because it is a perfect example of a woody stem. A stem of a plant is classified as being woody if it has certain characteristics. Woody stems tend to be bark covered. Woody stems also tend to be hard textured stems with secondary xylem. These stems are found on many trees and they provide more protection from the elements than other stems do: such as herbaceous stems.

7: Stem-herbaceous
I found this picture outside my dorm and I chose it because it was a very good depiction of a herbaceous stem. A stem of a plant is classified as being herbaceous if it has certain characteristics. Herbaceous stems are essentially the opposite of woody stems. They lack the hard, textured surface that woody stems carry and in their stead they have as soft, green, and pliable stems. In addition, these stems die at the end of the growing season, perhaps due to the lack of protection compared to the woody stem.

8: Epithelial tissue- This picture that I took of myself outside the dorms shows epithelial tissue, which is also known as skin. It is the outermost tissue of complex eukaryotic organisms. It serves the purpose of providing protection from numerous everyday threats. It also helps the overall structure of the organism by covering all the internal organs.

9: Pollen

This picture of these plants was taken near the SERC center at Rutgers. Pollen is necessary for plants to reproduce sexually. It is transported from the stamen of one flower to the pistil of another. Also, the pollen could be passed between these structures on the same plant, resulting in self-pollination. When the pollen lands on the stigma, it forms a pollen tube to the ovaries of the flower. The sperm cells from the pollen then travel down this tube to fertilize the egg and form another triploid nucleus. These two structures become the embryo and the endosperm, respectively, and they form the seed of the plant.

10: Pollinator: This picture taken near SERC at Rutgers was taken at the same place the previous picture was taken. The pollinator in the picture is the butterfly who is well known for its role in the pollination of plants. The butterfly is a pollinator because as it moves from plant to plant it transfers some pollen from one to another basically acting as a natural fertilizer for the plants.
