(5)Anther & Filament of stamen

· The stamen of a flower is the male reproductive organ of the flower. Each stamen generally has a stalk, the filament. The top of the filament are the anther & the pollen sacs. The anther is a pollen-bearing portion of the stamen. In this picture you can see the orange buds inside the pink petals. The anther is what you can see form the birds-eye view, containing the pollen in which bees and butterflies may come to pollinate. August 7^th, 4:32 p.m, Grandfather’s Pool

(7)Auxin producing area of plant

· Auxin is Indoleacetic acid that regulates the growth and development of a plant. The Auxin producing area of the plant is either the “apical shoot meristems” or the new buds/leaves. In the picture you can see the flowers that have already budded, and those that have not. The tip of the buds contain the Auxin that is needed for the flower to bloom.

(9)Carbohydrate- fibrous

· Fibrous carbohydrates are complex carbohydrates that usually come from green vegetables, essential to the digestion process. Full of fiber, they are the indigestible portion of plant material. By growing various vegetables like this pepper in our backyard garden, we have an unlimited supply of fibrous proteins. August 7^th, 10:54 a.m, Backyard Garden

(16)Heartwood

· Heartwood is the denser, inner part of a tree; developing as the tree gets older. In the picture of the old stump, you can distinguish the dark heartwood in the center by the ring of lighter sapwood that has not aged. August 7^th, 4:30 p.m, Grandfather’s Woods

(19)K-strategist

· K- strategists are species of organisms that uses reproductive “strategies” and survival to live a longer life. They protect their young and their population almost reaches the capacity of the environment, but remains stable. An Oak Tree is a common example of a K-strategist; they grow slowly, live long, and produce few offspring. August 7^th, 4:00 p.m, Neighbor’s House

(23)Mutualism example

· Mutualism can be defined as a type of symbiosis, a bond between two species that both benefit from the relationship. An example is pollination. Insects collect food resources from a plant, while in return the reproduction of the plant. In the picture a butterfly is collecting pollen from the flowers out front.

(26)Phloem

· Phloem is a food-conducting tissue found in vascular plants. It consists of sieve tubes, fibers, and other specialized cells. Inside the tomato stem is the phloem that conducts the sugar and glucose from the leaves during photosynthesis to other parts of the plant. August 7^th, 6:52 p.m, Garden

(35)Taiga plant (or a relative of one)

· The Taiga plant found in the taiga biome is long and cold. The plants have to be able to endure the cold, with thin, waxy leaves. They are usually coniferous trees that grow close to each other for protection of the harsh weather. The evergreen is a relative of the Taiga plants. With its thin, waxy leaves, it stays green year round and survives through the winter. August 7^th, 11:15 a.m, Front Yard

(36)Tendril of a plant

· The tendril of a plant is a threadlike, specialized stem that “climbing plants” use as support. We have a section of grapes we grow along the vines, however the deer got to it before we did so I took a picture of grapes from a grocery store. Regardless, both have tendrils that allow the grape vines to grow and cling on to the wires that are guided throughout the plant. August 7^th, 6:15 p.m, Kitchen

(39)Vascular Plant Tissue

· Vascular plant tissue is the conductive system of the plant consisting of the xylem and phloem. The xylem tissue conducts water while the phloem tissue conducts food. A tree is a common vascular plant due to its roots that conduct water, minerals, and provide assistance for the plant’s photosynthesis. August 7^th, 6:50p.m, Backyard

(40)Vitamin E- natural source

· Vitamin E protects cells from damaging effects from oxidation. It is sometimes added to food to slow down spoilage. A natural source of Vitamin E can be found in common spices and herbs. This picture is of the herb German Thyme that we have growing in our garden; however there are other natural sources of Vitamin E growing such as sage and parsley. Aug 7^th 5:57, Garden

(3)Amylase

· Amylase is an enzyme that helps break down sugars, carbohydrates, and starches in the digestive system. The enzyme converts starch and glycogen into simple sugars. My brother Nico is showing the saliva on his tongue that contains Amylase. August 7^th, 11:05 a.m, Nico

(4)Annelid

· Annelids are worms of the phylum Annelida. Their body is divided into both external and internal segments. This is one my brother and I dug up in our front yard. We were waiting for a rainstorm so that way they would all come out, but in Charlottesville it’s been dry. August 7^th, 12:20 p.m, Front Yard

(6)Arthropod

· Arthropods are a species of invertebrates with jointed limbs and a segmented body. They have an exoskeleton made of chitin; Arthropds include arachnids, crustaceans, insects, and centipedes. In this picture it is hard to make out the spider, but I found it, and its web, by almost walking right through it trying to find a tendril on one of our grape vines. August 7^th, 5:55 p.m, Garden

(8)Batesian mimicry

Batesian mimicry is where the insect evolves to disguise themselves as a predator of those they are a prey for. This protection is common among butterflies like this one nesting on the flower. August 7^th, 3:30 p.m, Front Yard

(21)Lipid used for energy storage

Lipids are used for energy storage: It is a substance in a cell that are either fats, oils, or waxy substances used for long term energy key to survival. In addition to common items like olive oil or beef, humans contain the lipids, fat, essential for our energy storage. August 7^th, 10:51 a.m, Myself

(28)Pollinator

A pollinator can be known as the “biotic agent” (vector) that moves the pollen of a flower from the male anthers to the female stigma to complete fertilization. Common examples are bees and butterflies like this one shown. August 7^th, 11:30 a.m, Front Porch

(29)Protein- Fibrous

Fibrous proteins are strong and insoluble and provide structure for organisms. There are three subgroups; keratin, collagen, and elastin. Keratin is a protein that can be found in hair, like my brother’s. August 7^th, 10:57 a.m, Lucas

(31) R-Strategist

R-strategists are species with a small, shorter lifespan. They produce many offspring, although a large majority does not survive. The R-strategists increase the possibility of survival by their large population of offspring. Insects are a common example of r-strategists, maturing fast without a stable population. August 7^th, 6:05 p.m, Front Yard

(32)Scale from an animal with a two-chambered heart

(32)Scale from an animal with a two-chambered heart.

· Some species have a two-chambered heart that supports single circulation. The two-chambered heart can be in found in fish, contrasted to reptiles and amphibians that have a three-chambered heart. Fishes have a two-chambered heart because they have gills, instead of lungs. August 7^th, 2:48 pm, Giant
