Summer Scavenger Hunt Part 2 (I just added it to part one, so part one is under this)
















ENDOTHERM: Well these are the two bunny rabbits from Kelsey Kowalski's backyard. We went there after camp and I thought it would be the perfect time to do my AP Bio! Well these bunnies are examples of endothermic animals. An endotherm is a warm-blooded animal that can generate its own heat to maintain its body temperature. The bunnies were cute, but the top one bites! Oh, and that's Bria in the picture. :)

















EXOTHERM: This is the pond in Kelsey's backyard. In the second picture, you can see Dara, attempting to find and torture the froggies...... just kidding, just find them haha. Frogs are examples of exothermic animals. Exotherms are cold-blooded animals and they get their heat from their environment.















ANIMAL THAT HAS A SEGMENTED BODY: In this picture lies a crippled grasshopper because it wouldn't stay still long enough for me to take the picture. Well this grasshopper has a segmented body. It is segmented into a head, thorax, and abdomen.


FRUIT-FLESHY WITH SEED: This is a picture of my crab apple tree that is on the side of my driveway. The second picture is when I smashed it with a cup. When I smashed it, there was some leakage and you can see two little seeds that were inside. Another example of a fruit that is fleshy and has seeds is a tomato.

STIGMA & STYLE OF CARPEL: Well the first picture is of the flower that I took in Mapleton and the second one is when I cropped it and labeled it. The stigma is the receptacle for pollen. The style is the stalk that connects the stigma with the ovary. The carpel is made up of the female reproductive organs.















GYMNOSPERM CONE: Gymnosperms are seed-bearing vascular plants that are cone shaped. I saw this tree on Mansfield Rd East when I was walking to Mapleton. Male cones are usually small while the female cones are bigger. This is because the males just need to produce the pollen while the females have to produce the seeds.

XYLEM: This plant has a really long stem. Part of this stem is the xylem. The xylem is responsible for transporting water and soluble mineral nutrients from the roots throughout the plant.
























INSECT: This is my insect. It's a cicada!. Well, I was too afraid to take a picture of it even though it was dead, so I took a picture of Kelsey taking a picture of it. Cicadas are the things that make that really annoying sound. It is used as a mating call by the males and sometimes attracts both females and males. Cicadas are insects belonging to the family Cicadidae.

POLLINATOR: That little bee there is a pollinator. A pollinator is an insect that carries pollen from one flower to another. The relationship between the insect and flower is a mutual relationship, meaning both sides benefit. Sorry that my camera pretty much is horrible. I did not want to get any closer to it either.








KERATIN: As you can see, this is my hair, skin, and nails. Keratin is the key structural material that makes up the outer layer of human skin. It also is a key component in the structure of hair and nails. Arthropods sometimes have their exoskeleton made partly of keratin.








PART 1


















COMMENSALISM: These two pictures were taken from the inside of my basement because I could not get a good picture from the outside. These pictures represent commensalism. Commensalism is a relationship between two organisms in which one of them benefit and the other does not benefit or suffer. This is a good example of this because the spiders make the webs on the plants so that they can have a home. It does nothing for the plant though. The plant is unaffected in this relationship.



CONIFER LEAF: As I was walking around my development, I came across this plant. I had to walk through some random person's lawn to get to it. Well this is a conifer leaf. Conifers are trees with needles or scalelike leaves and cones as opposed to broad, flat leaves. Conifers are classified as gymnosperms or plants with naked seeds not enclosed in an ovary.




ARTHROPOD: Here, stuck on my mouse trap, is an arthropod. An arthropod is an animal with a segmented body, exoskeleton and jointed appendages. Spiders are arthropods called arachnids. Arthropods include insects, spiders, millipedes, and crabs.






AUTOTROPH: This plant is an autotroph. An autotroph is any living organism that synthesizes organic substances from inorganic molecules by using light or chemical energy. The plant uses sunlight to convert carbon dioxide and water into sugars. This is called photosynthesis. Autotrophs are the primary producers in all food chains.







AMYLASE: Amylase is an enzyme that breaks starch down into sugar. Amylase is present in our saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in your mouth which is interesting.






EPITHELIAL TISSUE: This is sheets of tightly packed calls that line organs and body cavities as well as external surfaces. The skin and the linings of the various passages inside the body are made of epithelial tissue. It provides a covering for deeper body layers.








MUTUALISM: This is an example of mutualism. Mutualism is a symbiotic relationship where both organisms benefit. The bee and the flower are both benefiting in this picture. That is because the flower is getting its pollen passed from one individual to another. The bee benefits by getting the nectar or pollen. The nectar or pollen are a solid food source.






THORN OF A PLANT: When I saw this, I had to use this as one of my items. These thorns are crazy and they just look painful. A thorn is a branch of a plant that becomes woody, hard and pointed. I would think that the point of thorns is for protection of the plant.








POLLEN: It is kind of cool how you can see my reflection in my phone. ;) Anyway, this is pollen. Pollen is the fine spores that contain male gametes and that are born by an anther in a flowering plant. Pollen is transported by pollinators such as bees or moths.























DECIDUOUS LEAF: This is a deciduous tree/leaf. Being deciduous means that the leaves fall off at maturity and in plants, it is the result of natural processes. It could also mean that the leaves fall off or dry out during a certain season. Well during the winter, these leaves will fall off and grow back later. The leaves will also turn brown.

AP Bio Summer Scavenger Hunt

Dicot plant with flower and leaf: This geranium on my deck is a dicot plant for two reasons. The first is because there are eight petals on the flower directly above the bracelet, and the second is because the leaves are netted, meaning that the veins in the leaf all connect to one another and fan out. A dicot flower usually has either four (or multiples of four) or five (or multiples of five) petals, and netted leaves.

Keratin: I wanted to get a picture of a white tailed deer that has been spotted occasionally around my neighborhood, but since I could not find it, I decided that the next best thing would be my friend's goat, Petey. His horns are made up of keratin, which makes up the hair, nails, and horns of all mammals. On deer, the antlers and feet are also made up of keratin.

Endotherm: An endothermic organism is one that can create its own heat to maintain its body temperature. These male and female goldfinches on the thistle feeder in my backyard are warm-blooded.

Thorn of a plant: This is a picture of a rose bush by my house. On the stems of the plant are thorns. The rose developed thorns to protect it from predators that would want to eat the flower. Thorns stick into the attacker's skin or fur and cause discomfort, and are not easily digested if swallowed.

Insect: In this picture is a lightning bug (also known as a firefly) that was caught in the backyard at dusk. The lightning bug is an insect, in that it has 6 legs, a segmented body, and antennae. The bug also has wings, another characteristic of most insects.

Fruit-fleshy with seed: This is a picture of a pepper from my garden. Though we use it in salads with vegetables, this pepper is technically a fruit. Fruit is the matured ovary of a plant, and protects the dormant seeds until they mature. Vegetables are merely parts of plants, therefore not fruits.

Flower ovary: In this photograph is the carpel of a lily. At the base of the carpel is the flower ovary. The flower ovary holds the ovules, which once fertilized by pollen become seeds.

Style and Stigma of a Carpel: This carpel was obtained from a Stargazer lily. The carpel is considered the female sex organ of the plant. At the top of the plant segment is the stigma, which traps pollen, and the lower section is called the style. The style connects the stigma to the flower ovary.


Deciduous Leaf: This leaf was taken from a deciduous sugar maple from my front yard. Deciduous trees shed their leaves annually, towards the end of their growing season so the trees can conserve energy and water for the unfavorable times of the year (such as the autumn season and droughts). When the leaves start to die, they transform from green to a variety of colors, like red, yellow, and brown. Shortly after, the leaves fall to the ground, leaving the trees bare.


Conifer Leaf: Most conifers are cone bearing trees, such as pines and ferns. Conifers shed their needles frequently throughout the year, but not all at once like deciduous trees. These needles are from a white pine tree in the driveway.
