Lichen: The symbiotic collective formed by the mutualistic association between a fungus and a photosynthetic alga or cyanobacterium.

Anthropod

*Robin M.
Anthropod: A segmented coelomate with a chitinous exoskeleton, jointed appendages and a body formed of district groups of segments.

Commensalism

*Robin M.
Commensalism: A symbiotic relationship in which one organism benefits but the other is neither helped nor harmed.

Actin


*Robin M.
Actin: A globular protein that links into chains, 2 of which twist helically about each other, forming microfilaments in muscle and other contractile elements in cells.d

Long-Day Plant


*Robin M.

Long-Day Plant: A plant that flowers in response to a long photoperiod.

Mutualism

*Robin M.
Mutualism: A symbiotic relationship in which both participants benefit.

Actin



2. actin - a globular protien that links into chains two of which twist helically about each other, forming microfilaments in muscle and other contractile elements in cells. The actin helps with muscle contractions like when we bend our fingers or to type on a computer.

R-Strategist


*Robin M.
R-Strategist: A species characterized by having rapid development, high motility, and a high reproductive rate relative to a K-strategist.

K-Strategist


*Robin M.
K-Strategist: My friends and I am are long body structure.

Glycogen


*Robin M.

Glycogen: An extensively branched glucose storage polysaccharide found in the liver and muscle of animals.

-Since glycogen is an extended form of glucose, sugar is best represented as a form of glycogen.

Radial Symmetry

*Robin M.
Radial Symmetry: Characterizing a body shaped like a pie or barrel, with many equal parts radiating outward like the shapes of wheels.

Autotroph


*Robin M.
Autotroph: An organism that obtains organic food derived from other organisms.

The plant leaf is an example of an autotroph.

Leaf


*Robin M.
Leaf (Gymnosperm): "Gymnosperm" means naked seed.
-Picture of a leaf!

Flower Ovary


*Robin M.
Flower Ovary: A part of the female reproductive organ of the flower or gynoecium.
-The picture is of a female flower.

Part of this flower has an ovary, but it is a female flower.

Phloem

*Robin M.
Phloem: Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant.
-The picture of the flower represents the plant and the phloem.

Fruit (Fleshy with Seed)


*Robin M.
Fruit (Fleshy with Seed): A firm structural fruit, with a pulpy covering over a seed, or fleshy pulp.
-This apple is a fruit with fleshy seed.

Parasite

*Robin M.
Parasite: An organism that benefits by living in or on another organism at the expense of the host.
-This picture represents the parasite in the organism.

Keratin


*Robin M.
Keratin: An extremely strong protein which is a major component in skin, hair, nails, hooves, horns, and teeth.
-This picture represents the Keratin in my nails(red), and my sisters.

Pollen


*Robin M.
Pollen: Fine spores that contain male gametes and that are borne by an anther in a flowering plant.
-This picture is one of my own photos, used in my photography class (Mrs. Hall). It represents a flower that is pollinated.

Insect


*Robin M.
Insect: A special group of small air-breathing arthropods.
-A fly on my porch windowsill. Represents the insects.

Abscisic acid




1.abscisic acid - a plant hormone that slows down growth often antagonizing actions of growth hormones. What the abscisic acid does for the plant in the picture above promote seed dormancy and facilitate drought tolerance.

Connective Tissue


*Robin M.
Connective Tissue: Tissue of mesodermal origin consisting of e.g. collagen fibroblasts and fatty cells.
-My hand is a connective tissue and ear.

Adaption of an Animal

Something about an animal that makes it easy for it to live in a particular place in a particular way. It usually takes an animal some time to adjust to a new enviorment. When I first got my dog Brownie, it was Summer and he lived outside until Winter, then we let him in the house. he is still adjusting.

Cuticle Layer of a plant


The Cuticle layer is the non-cellular protective layer of the outer layer of plants. The best way to understand it is to compare it to human skin, in that it helps protect the plant's insides from harmful agents.

Autotroph


Autotrophs are organisms that produce organic compounds from inorganic molecules.These flowers are autotrophs because they use light(inorganic molecule) to create sugar(organic material).

Pine Cone-Female


This is a female pine cone or a seed cone. Under each scale is originally an ovule and the scales are opened to allow pollen to enter. After the ovules are pollinated the scales close until seeds are ready in which the scales open again to release the seeds and repeat the process.

Amylase


Amylase is an enzyme that is used to break down starches into sugars. It's done in the pancreas, plants, and some bacteria but mainly in human saliva on the tongue.

Cellulose

Cellulose is the cheif substance composing the cell walls or fibers of plant tissue.

Niche

A niche is the particular role of an individual species or organism in its environment, including its position in the food cylce, its habitat, and its behavior. This is a picture of a tree with big spider web. The spiders live in this tree and they catch their food using this web.


Cambium


Cambium is a layer of formative cells between the wood and bark of plants like trees. These cells cause the circumference of the stem to increase by dividing and differentiating to form new xylem and phloem tissue, which will eventually become bark, as seen here.

Angiosperm



A plant whose ovules are enclosed in an ovary; a flowering plant. This cut down oak tree is an example of angiosperm since it flowers daily.

Autotroph

This is a picture of the leaves of a Hosta plant, which is an autotroph because it is capable of making its own food by photosynthesis.
Dicot flower and leaf

This is a dicot flower. It has net like veins and there are usually 4 to 5 petals on the plant. If you look at the fallen flower on the brick you will see it has 4 petals.

Fruit-fleshy with seed



has a soft and pulpy wall consisting largely of soft succulent tissue; rarely dehiscent. These strawberries are an example of it since their seeds lie on the outside and it has a soft wall.

Insect



an air-breathing invertebrate animal arthropod with a body that has well-defined segments, including a head, thorax, abdomen, two antennae, three pairs of legs, and usually two sets of wings. This small beetle is an example of an insect.

Amylase

Amylase is an enzyme that helps change starch into sugar and it is found in saliva and Pancreatic juice.

Heartwood



central wood of tree; the wood at the center of a tree trunk or branch that is older, darker, and harder than the wood surrounding it. This chopped down tree found in my back alley is an example of heartwood.

Frond


This a picture of my mother's fern. A fern is a frond because it is a big leaf with many divisions. Another example of a frond would be a leaf of a palm tree.

K-strategist

Brandon(my dog), my mom, and I are all k-strategist. This is because we have large body size, long life expectancy, and the production of fewer offspring, that require extensive parental care until they mature.

Cuticle Layer of a Plant



The Cuticle layer of a plant can simply be defined as the waxy layer of a plant that prevents UV radiation and too much water loss. The cuticle layer also functions in defense, forming a physical barrier that resists penetration by virus particles, bacterial cells, and fungi.

Annelid

An Annelid can be defined as any of various worms or wormlike animals of the phylum Annelida, characterized by an elongated, cylindrical, segmented body and including the earthworm and leech. This is just a picture of a worm that I found in my backyard.

Bryophyte


In this picture there is moss on the bark of this tree. Moss is a Bryophyte, which is a subdivision of nonvascular plants including liverworts and hornworts too. Bryophytes generally live on land but are mostly found in moist environments.

Autotroph

Trees are organisms that obtain organic food molecules without eating other organisms or substances derived from other organisms. This is why this tree is considered to be an autroph.

Parasite

Dogs can sometimes carry flees. Flees is one example of a parasite. A parasite is an organism that absorbs nutrients from the body fluids of living things. My dog, Brandon is the example of a dog that can carry a parasite.

Pollinator

Bees are pollinators. They are organisms that transfer pollen from one place to another.
