Muscle Fiber - Striated

Striated muscle fibers allow voluntary movement of body parts and promotes locomotion. They also aid in posture and heat production. Striated fibers contain many peripheral nuclei and can be found in skeletal muscle tissue. Many muscles can be found in my leg, as the bones need protection and need to move.

Cellulose

A carbohydrate that makes up most of a plant's cell wall. It is a polysaccharide (many sugar molecules bonded together) that provides stability to the cells within the plant. It functions in protection and support. My tomato plant shown in this picture has cellulose located inside its cell walls.

Monocot Plant with Flower & Leaf

Most monocot plants (herbaceous plants) are annual plants and tend to be thinner than woody (dicot plant) stems. They're usually softer, more bendable and greener. The stem dies down to soil level at the end of a season. Monocot plants are often referred to as herbaceous plants. Both monocots and dicots are flowering plants, but monocots have parallel leaf veins, one cotyledon, flowers in multiples of three and no cortex. Grass is an example of a monocot plant.

Radial Symmetry

A type of symmetry that radiates from the center as if a continuous circle were being drawn ring after ring. Some examples of radial symmetry are starfish, the sun and flowers, as shown in this photo.

Niche

An environment or habitat that provides the necessary elements needed for an organism to survive and live. The bee's nest in the photo is a perfect example of a niche. In here, the bees thrive with their honey and pollen and raise their young bees with the protection that the hive provides for eggs.

Insect

A small arthropod (class of insects) which has no backbone and a segmented body. An insect can range in size and usually has numerous legs. An ant is an example of an insect because it has a segmented body along with numerous legs. The ant is the tiny black spot in the photo.

Dicot Plant with Flower and Leaf

Dicot plants are similar to monocot plants but have slight differences. Dicot plants have two cotyledons, the leave stems are branched and petals of flowers have petals in multiples of four or five. The stems of these plants that have been in the process of growing for two or more years and are not annual plants. Following these two years, the plant stem gets thicker and more sturdy than a monocot stem. Dicot (woody) stems can be as large as a tree trunk or as small as the stem shown in this photo. Some examples are peas, beans and tomatoes as shown in this picture.

Deciduous Leaf

Deciduous is defined as a tree or shrub that sheds leaves annually, or every year. The leaves do not last. Here in New England, we see many deciduous leaves, as shown in this photo.

Heartwood

The innermost part of a tree trunk that is the thickest. You can see the very center of the tree trunk in this photo of a cut tree.

Pollen

A usually yellow, powdery substance that is let out or discharged from the male part of a flower. The anthers of a flower are sticky in order to obtain the pollen. The photo of the flower represents where pollen exists and plays its main role: plant reproduction. Not only is pollen an important part of plant reproduction, but it is also a source of annoyance for many people with allergies. In the picture, the anthers can be seen where the pollen attaches itself to in the very center of the flower.

Autotroph

A plant that is able to create its own food and fill its nutritional needs through photosynthesis. This plant here provides for itself through photosynthesis as shown by its green leaves.

Thorn of a Plant

Thorns in plants are an adaptation of the plant which protect the plant from being eaten or destroyed by other plants or animals. Thorns may also be helpful for spreading the vegetation of the plant they are on because they may stick to predators moving in several different places and locations. The rose bush in the photo is an infamous example of a plant with thorns.

Long-day Plant

Plants that have flowers that bloom only when they receive more than twelve hours of sunlight per day. They bloom only when the days are long, where there is less darkness, especially during the summer months. Some examples are spinach, potatoes and lettuce, seen in this picture.

Globular Protein

Proteins that are at the tertiary structural level of proteins which are foldings of alpha helices or beta-pleated sheets. They are spherical in shape containing tertiary and quaternary structures. Globular proteins may be found in the hemoglobin (transports oxygen) in your blood. There is blood circulating throughout the body, so the picture of my hand represents the blood where the hemoglobin and therefore the globular proteins exist.

Fibrous Protein

Linear proteins that are extended and strand-like. Fibrous proteins may be found in hair, nails, etc. They make up many of the fibers within our body like collagen fibers and elastin fibers. This photo shows a place where fibrous proteins may be found: the nails.

Myosin

A protein that works with actin to make up the contractile filaments within a muscle cell in order for the muscle to move. In the photo, my muscles were able to contract and move as a result of the work of myosin in the muscle.

Ethylene

A gaseous hormone that is often associated with fruit ripening; a plant growth substance. You cannot see ethylene or smell it. Although ethylene contributes to plant growth and ripening, it can also damage the plant. Ethylene in high concentrations may be explosive. The color of different fruits or plants whose growth is influenced by ethylene may be determined in part from the ethylene. The banana shown in the photo is an example of a fruit encouraged to ripen under the influence of ethylene.

Keratin

Keratin is a vital protein to have in your body. It can be found in your integumentary system, your hair and nails. Lots of animals have keratin in their bodies. Keratin is a type of fibrous protein which are linear and strand-like. Keratin can be found in hair, which is shown in this photo.

Epithelial Tissue

One of the four major tissue types whose main purpose is to protect and cover organs in the body. The cells within the tissue are tightly packed to prevent leaks. It can line your cavities and form glands which secrete hormones and chemicals. The epithelial tissue's basement membrane connects it to the underlying connective tissue. My whole body is covered with skin, but the picture shows my arm.

Amylase

An enzyme that can be mainly found in our saliva which breaks down starches into simple sugars. Amylase plays a large role in digestion. Amylase may be found in teardrops or saliva. Saliva is shown in this photo.

Actin

A protein that works with myosin to make up the contractile filaments within a muscle cell in order for the muscle to contract and move. In order to make the fist in this picture, it was necessary for actin to work with myosin in order for the muscle to contract and make the fist.

Fruit - Fleshy with Seed

Fleshy fruits with a seed are fruits that are formed from a single or group of flowers and have one or more seeds in them. The apple in this photo has multiple seeds and is an example of a fleshy fruit with a seed(s).

Fruit - Dry with Seed

Dry fruits with a seed are fruits with a "seedpod" like peapods or beans in which the pod may be opened up to expose the seed(s). The green beans in the picture need to be opened to expose the actual seed.

Amniotic Egg

An egg that contains a shell and in which an embryo develops inside of an amniotic sac that is filled with fluid and is sustained by the yolk within the egg. My photo shows a chicken egg, an example of an amniotic egg filled with amniotic fluid and a yolk.

Eukaryote

Animals or fungi with an enclosed nucleus and numerous organelles. It is the opposite of a prokaryote, which has no nucleus. Lucky, my dog, is an example of a eukaryote because she is made up of many cells with enclosed nuclei and organelles.
