| Xylem Xylem is a transportation system. It carries water and minerals to the tree. The rings shown above are old xylem tissue. Each ring represents a year, by counting the xylem rings you are able to determine the trees age. |
 |
| Phloem The phloem is the second layer of the bark. It carries the sugars from its leaves to its roots. it also carries nutrients to the tree. |
|
| Heartwood The heartwood is the center or the heart of the bark. It is the strongest part of the tree. Above you are able to see the heartwood it's the center layer of the bark. |
 |
| Fruit-fleshy with seed Fruit that is fleshy with seed has a thick flesh and is smooth skinned. The apple shown above is an of fruit-fleshy with seed; pears, crab apples, strawberries, and kiwi are other examples of fruit fleshy with seed. |
 |
| Cambium Cambium is a thin layer of tissue that can be found between the bark and the wood of a tree. It creates new layers of phloem which increases the diameter of the tree. The cambium shown above is the outer layer of wood. |
 |
| Protein-fibrous My nail is a good example of protein-fibrous. It is strong and insoluble which helps support and protect organisms. Protein-fibrous can also be found in hair, blood vessels, cartialage, bird feathers, and ligaments. |
 |
| Endotherm Endotherm is referred to mammals such as birds, dogs, and cats. It can also be referred to some fishes, insects, and plants. Endotherms are able to control their body temperature unlike ectotherms. |
 |
| Deciduous Leaf The deciduous leaf can be found in many trees here in Chicago. These leaves fall each year and turn into different colors such as red or yellow. When autumn comes along many leaves like the ones shown above will fall and turn inot different colors. |
 |
| Endosperm Endosperm is the tissue produced in plants during fertilization. It protects the embryo by surrounding it and it also provides nutrition in the form of starch. Endosperm is good to the nutrition of humans. The white part of this coconut is the endosperm. |
 |
| Keratin Keratin is a strong protein fond in skin, hair, nails, and teeth. Keratin has unique properties it can be non-flexible and ahrd like teeth, it can also be soft and flexible like hair. The keratin we as humans interant with is already dead. Our hair, skin, and nails are made up of dead cells. |
 |
| Genetic Modified Organisms GMO stands for genetically modified organisms. A lot of the food we eat is genetically modified such as this tomato. Plants are modified in a laboratory to be able to get the desired traits. Some traits are resistance to pests and diseases; also the tolerance to the cold and herbicide. |
 |
| Gymnosperm Cone Gymnosperm cones are found in needle like and evergreen plants. This seed doesnt grow like most seeds that grow in ovules. This seed grows in the form of a cone. |
 |
| Carbohydrate-fibrous An onion is an example of carbohydrate-fibrous. They are a good source of vitamins, fiber, and minerals. It helps the digestive system run without problems. |
 |
| Frond A frond is a large leaf such as the palm leaf shown above. The leaf is divided into segments but not all fronds are divided. |
 |
| Amniotic Egg An amniotic egg is an egg that has an amniotic membrane. It allows the embryo to develop protected form desiccation. Reptiles and birds are a few examples of organisms that produce amniotic eggs. |
 |
| Autotroph This plant is an autotroph because it is able to make its own food through photosynthesis. It uses water, carbon dioxide, and solar energy which convert into sugars and oxygen. |
 |
| Flower Ovary A flower ovary is the reproductive organ of a plant, which is shown in this picture. It is attached to a pistil which can be found in the bottom or top of the ovary, which is also shown in this picture. |
 |
| Ectotherm The lizard shown is an ectotherm. It is a cold blooded creature that has the same body temperature as its surroundings. It isn't able to control its own body temperature. |
 |
| Cuticle Layer of a Plant This picture shows the top of a plant leaf which is were you are able to find the cuticle layer of a plant. The cuticle layer is a protective layer that covers the outer cell layer. It protects the plant from things such as UV radiation. |
 |
| Conifer Leaf This shows a conifer leaf; you are able to see its needle like shape. You can also distinguish a conifer because its seeds are out in the open; they aren't protected by an ovary. Most conifers are evergreen plants. |
