Stem-Woody



A woody plant is a plant that uses wood as its structural tissue.

Protein Fibrous



The keratin in hair is a fibrous protein. Fibrous proteins form rod-like shapes and are usually inert structural or storage proteins.

Insect


Insects are a class of living creatures within the arthropods that have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes, and two antennae


Annelid; Animal With Segmented Body

These worms are annelids. They are characterized by an elongated, cylindrical, segmented body. Leeches are also annelids. They have movable bristles called setae used as a sensory organ.

Anther and Filament of Stamen


This flower contains an anther and filament. The filament is a long tube and the anther is a sac on top of the filament where the pollen matures.

Bryophyte

This moss is a bryophyte. It does not have the tissues xylem and phloem that circulate water and nutrients in vascular plants. Bryophytes live on land but are usually found in moist environments. They have free- swimming sperm that require water for transportation.

Cellulose


This lettuce contains cellulose. Humans are unable to digest cellulose because we don't have the enzyme necessary to digest it. For humans, cellulose is the fiber which aids in the smooth working of the intestinal tract.

Chitin


Chitin is found on the outer skeleton of these shrimp. It is used in many functions of the shrimp. Chitin is used to produce chitosan, which is used as a wound healing agent, a sizing and strengthening agent for paper, and a delivery vehicle for pharmaceuticals and genes.

Fermentation


This wine is a result of alcoholic fermentation. Sugar is used to form ethyl alcohol, and a by product of Carbon Dioxide.

Thorn of a Plant

This rose bush has thorns on it. They are short, hard, pointed on a stem of a plant. The thorns may serve many functions to the rose.

Pollen


Pollen contains the male gamete of seeding plants. It is a coarse powder and must be able to protect the sperm from outside conditions. Pollen is realeased from the style of a plant and taken in by the stigma of the same or a different plant.

Arthropod



This butterfly is an arthropod. It is an invertebrate, has an exoskeleton, and jointed appendages.

Woody Stem


The stem of this tree is covered in bark ("wood") this makes it a woody stem. Woody stems are not very flexible, but provide good support, structure, and protection.

Gymnosperm Leaf


These pine needles are gymnosperm leaves. The seeds of the pine tree are not enclosed in a fruit. Instead they are on the needles that it produces.

Scale of an Animal With a Two-chambered Heart


These koi have two chambered hearts because they are fish. There scales help protect them against some predators.

Gymnosperm Cone


This pine cone's seeds are not enclosed inside the plant's ovary. Instead they are on the outside of the cone, making it a gymnosperm cone.

Autotroph


This lantana is an example of an autotroph. It is able to produce its own food from photosynthesis.

Fibrous Protein


These beans are fibrous proteins. They are used by the body to form connective tissue, tendons, and bone.

Parasite


This ivy becomes a parasite as it grows on a tree. It roots into the tree and steals its nutrients.

Keratin

Keratin is a fibrous protien that assembles into fibers. Keratin is an unsolvable, tough tissue that makes up hair, nails, the outer layer of skin.

This ant is an insect. An insect is under arthropods. They have six legs, and 3 segments of their body: head, thorax, and abdomen. They also must have compound eyes and and two antennas

Heartwood


This is the heartwood of a juniper. It is the rich brown color at the center of the wood. It is believed to be dead and becomes structural.

Epithelial Tissue


My hand is covered in epithelial tissue, and so is my entire body. It protects my bodies internal organs and helps me secrete, feel, absorb, and clean my body.

Exoskeleton


These beetles all have exoskeletons to contain their organs. The exoskeleton also provides structure for the organism.

Woody Stem


This pine tree trunk is an example of a woody stem. It has been growing for 2 years or more and can now support the life of the tree, and be called a woody stem.

Conifer Leaf


Conifer Leaves are leaves are non-deciduous and do not have branched veins. They are generally designed in needle/narrow shape to sustain water levels. (Conifer on left and deciduous on right.)

Carbohydrate-Fibrous


Broccoli is a fibrous carbohydrate because it contains high amounts of dietary fiber which is essential for proper digestion and excretion. Fibrous carbohydrates also have many essential vitamins.

Calvins Cylcle

The Calvin cycle is a process of turning CO2 and other carbon-chained molecules to create glucose and other sugars. The process mainly occurs in leaves and at night.

Arthropod


This spider is an arthropod by its exoskeleton, segmented body, and jointed appendages

Amniotic Egg


This birds nest contains amniotic eggs laid by a bird. The amniotic egg provides a safe environment for the amniote to grow and mature.

Adaptation of a Plant


This plant has adapted over time by developing thorny leaves to help ward off predators and stop them from eating it.

Endotherm


Rachael and I are endothermic because we maintain our own by heat is different ways such as metabolism, shivering, and sweating.

WOODY STEM



this is a WOODY STEM. it is the trunk of a small tree. it is made up of cellulose and lignin

HERBACEOUS STEM



this is a HERBACEOUS STEM because it looks and functions like a leaf

XEROPHYTE



this is a XEROPHYTE because it is a plant adapted for life with limited water supply

CONNECTIVE TISSUE



this meerkat has CONNECTIVE TISSUE which is the tissue that connects, protects, and surrounds organs in its body

XYLEM



this is a wood stem, therefore it is made up of XYLEM which is a primary component of wood.

THORN OF A PLANT



this plant has THORNS which are modified plant organs that are stiff and end in a point

EUKARYOTE


this adorable little elephant:) is a EUKARYOTE because it has multiple cells that each have a membrane enclosed nucleus and membrane enclosed organelles

KERATIN



my hair has is made up of KERATIN which is a primary protien that makes up hair, nails, and skin

AUTOTROPH




this flower is an AUTOTROPH because it uses the sun to produce its food internally using photosynthesis


POLLEN



this flower has POLLEN which is the powder substance shed by anthers of plants. it is used to help plants produce flowers

INSECT



this bee is an INSECT because in the adult stage it is a 6 legged anthropod that has a segmented body and an exoskeleton


this is a picture of THE CUTICLE LAYER OF A PLANT. the cuticle layer of a plant is the waxy coating that helps prevent dessication, which is when the plant loses its water to air.

ECTOTHERM



ECTOTHERMS use the external environment to maintain a stable body temperature, like this tortoise

POLLINATOR



this bee is a POLLINATOR because it spreads pollen from one plant to another in order to pollinate them so they can bloom.

ENDOTHERM



This is a picture of an ENDOTHERM because, even though i look pretty rough and am in my pajamas, my body is warmed by heat that is generated by metabolism. the heat is used to maintain a normal body temperature.

Littoral Zone Organism



This is a southern stingray. In oceanography and marine biology, the littoral zone is extended roughly to the edge of the continental shelf. Inside of this region is the southern stingray. These stingray are found in the tropical and subtropical waters of the western Atlantic Ocean, the Caribbean, and the Gulf of Mexico. They make their home in shallow coastal waters. Normally southern stingrays bury themselves in the sand with only their eyes visible. These rays are one of the only species of rays to stay in such shallow water. Occasionally the rays can be seen in deeper waters, but they will mostly be found in 1 to 40 meters.

Radial Symmetry



This starfish is an example of radial symmetry. Radial symmetry is when an organism has a basic body plan in which it can be divided into similar halves by passing a plane at any angle along a central axis.

Stigma & Style of Carpel



On the tip of the flower is a stigma and style, of a carpel. A carpel is the ovary, stigma, and style combined. The stigma is what catches the pollen and the style connects the stigma to the ovary.
