Endotherm: My calf Melody is an endotherm which means she is a warm blooded animal capable of maintaining and controling her own body temperature. Usually her body temperature is and should be higher then the temperature of her environment.

C4 Plant. Cactuses are types of c4 plants. I took this picture at work, because I work at a greenhouse. C4 plants have that characteristic of living in a better enviroment where its very dry and sunny. Cactuses show a perfect example of them because they normally live in an enviroment where it is not rainy and wet.
Angiosperm. This picture of a lilly I took in my backyard represents angiosperm. Lillys are a flowering plant. That means that they produce seeds inside of them.

Biology Collection 1: Hunter Pates
Gymnosperm cone- (“naked seed” plants) This is a picture of a pine cone which is a gymnosperm cone. A gymnosperm has seeds that are not enclosed in an ovary.
Xylem- Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant. Inside the lines of this leaf is the xylem.
Long-day plant- A plant that flowers in response to a long photoperiod. They usually flower in late spring or early summer, when light periods lengthen. Clovers are long-day plants.
Woody Stems- The stems of plants who have been growing for two years or more. After two years, a plant's stem thickens to accommodate growth and increased circulation in a plant. Probably the most noticeable example of a woody stem is a tree trunk. This plant has woody stems.
Thorn of a plant- Thorns likely first developed as a defense mechanism in plants. Thorns, spines, and prickles are very much alike, though are derived from different plant organs. The picture I have taken is of a prickle.
Cuticle layer of a plant- This is a picture of a leaf and it's cuticle layer. The cuticle layer is the protective layer covering the outer cell layer of the green, above ground parts of land plants.
Insect- A class within the arthropods that have a chitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. This fly is a common insect that possesses all of the characteristics just described.
Deciduous leaf- A leaf on a deciduous tree, that falls off after it is no longer needed. This leaf is green now, though starting in Autumn it will change color and then fall off. Deciduous also has a similar meaning when referring to animal parts such as deciduous antlers in deer, and deciduous teeth (baby teeth).
Fruit - fleshy with seed- This strawberry is considered a Pseudocarp, a false fruit, because it does not contain the seeds. The seeds are achenes, on the outside of a fleshy fruit.
8. Radial Symmetry: Radial Symmetry is symmetry of an object which had no distinct left or right side, just a top and a bottom. As a perfect example of radial symmetry, I found a jellyfish (still living I think) washed up on the shore. Although in that state, it did not appear symmetrical, it would have been symmetrical floating in the water. The type of jellyfish I found was a Man-of-war Jellyfish. Its colors were vibrant purple and pink, almost fluorescent. The colors were so beautiful and I didn’t ever think that colors like that could possibly be natural.
5. Thorn of a plant: While outside taking my 10 pictures for my collection, I made the mistake that I’m sure many other people have made; I used a rose bush as my example of a plant with thorns. However, while researching, I learned that the sharp objects on the stem of a rose are not thorns; they are prickles, which are completely different, although the two are commonly confused. Some examples of plants with thorns are lemon, pomegranate, and wood apple. The purpose of these thorns is to protect the plant from scavenging animals.
3. Herbaceous stem: The herbaceous stem that I took a picture of belonged to a red flowered plant growing outside my hotel. Herbaceous stems are usually flexible stems lacking woody tissue. Most herbaceous stemmed plants are annual, biennial, or perennial and their stem grows as cells divide by mitosis in the apical meristem. A herbaceous stem also typically dies down to soil level as their growing seasons come to an end. Flowers, ferns, and most ground-planted vegetables are examples of plants with herbaceous stems.
2. Annelid: The term annelid derives from the French word for “ringed ones.” Annelid refers to a large phylum of segmented worms, including earthworms, ragworms, and leeches. Segmented worms often have similar sets of organs located in each segment. My example was a dead earthworm that I found on the sidewalk. Earthworms are obvious examples of annelids because as many people are aware, cutting an earthworm in half will not kill it. This is because of its segmented structure consisting of more than one set of organs.
1. Eukaryote: As an example of a eukaryote, I used Hannah. A eukaryote is any organism, unicellular or multicellular, whose fundamental structure unit is a cell consisting of membrane-bound organelles and a distinct nucleus. Eukaryotes are also capable of cellular division through mitosis or meiosis. All animals, plants, fungi, and several microorganisms are considered eukaryotes.
Collected items for AP Bio
Fleshy Fruits with seeds can be subdivided into those formed from a single flower and those formed from a group of flowers. This fruit has fleshy surface with seeds inside.
Dry Fruits can be divided into those in which the seeds are contained in a seedpod of some sort which opens to release the seeds and those in which there isn't a seedpod which opens. This is a almond which is a seed from a fruit.
Thorns represent the modification of an axillary shoot system in which the leaves are reduced. This is a close-up of a thorn plant that i found in North Jersey. This plant uses its thorns to keep away herbivores
A pollinator is the biotic agent that moves pollen from the male anthers of a flower to the female stigma of a flower to accomplish fertilization. This bee would take pollen from other plants and pollinate.
