1. This is an example of the cuticle layer of a plant. The cuticle layer is the thin, waxy protective coating on the leaf of a plant.












2. This is an example of an autotroph. An autotroph is an organism that produces complex organic compounds from simple inorganic molecules using energy from light by photosynthesis.









3. This is an example of a biome. It is a picture in Scotland of grassland. A biome is a living community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region. Some examples of biomes include; deserts, tundra, tropical rain forests, grasslands, savannas, deciduous and coniferous forests.







4. This is an example of adaptation of an animal. This horse is used for horse racing in Ireland. The horse has adapted to living it's life as a racing horse, and to living at the stud farm.

















5. This is an example of radial symmetry. Radial symmetry is a form of symmetry in which the parts of an organism are arranged concentrically around a central oral/aboral axis and more than one imaginary plane through this axis results in halves that are mirror-images of each other. This pear shows radial symmetry.









6. These cows are examples of endotherm. An endotherm is a warm-blooded animal species which maintains thermal homeostasis, or a constant body temperature.










7. This is an example of succession. It is a picture of St. George's Canal, which over the summer loses most water. Succession is more-or-less predictable and orderly changes in the composition or structure of an ecological community. Succession may be initiated either by formation of new, unoccupied habitat or by some form of disturbance of an existing community.






8. This is a picture of my friend's arm, which is an example of epithelial tissue. Epithelial tissue is a tissue composed of cells that line the cavities and surfaces of structures throughout the body. Skin is an example of epithelial tissue.









9. This onion is an example of a plant which is produced asexually. Asexual reproduction is reproduction which does not involve meiosis, ploidy reduction, or fertilization. Only one parent is involved in asexual reproduction.









10. This yogurt represents fermentation. Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound. In the presence of abundant oxygen, yeast cells greatly prefer fermentation to oxidative phosphorylation, as long as sugars are readily available for consumption.





11. This is an example of a flower ovary. A flower ovary is an ovary in a part of the female reproductive organ of the flower or gynoecium.











12. These are examples of carbohydrates. Carbohydrates or saccharides are the most abundant of the four major classes of biomolecules. They fill numerous roles in living things, such as the storage and transport of energy and structural components.








13. This potato is an example of a long-day plant. A long-day plant requires a longer period of light than just daylight to flower.












14. Lettuce is also an example of a long-day plant.













15. The stem of my plant is an example of meristem. Meristem is the region of cells capable of division and growth in plants as the tip of a stem or root.










16. This plant shows adaptation. Adaptations are special features that help plants or animals to live in a particular habitat. This plant has grown where the sun is mostly present.










17. These are examples of proteins. Proteins are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. Different meats are examples of protein.










18. This is a picture of my hair, which is brown. This represents the dominant gene. The allele that masks the other is said to be dominant to the latter, and the alternative allele is said to be recessive to the former. Brown hair is dominant to blonde, which is recessive.








19. This ripe tomato, and ripe apple are examples of ethylene. They release ethylene during the ripening process. It is the simplest alkene. It is a plant hormone, but different from the rest being that it is a gas.









20. This tomato is an example of gibberellins. Gibberellins are plant hormones that regulate growth and influence various developmental process, including stem elongation, germination, dormancy, flowering, sex expression, enzyme induction and leaf and fruit senescence.








21. This is an example of an amniotic egg from a chicken. An amniotic egg is a water retaining egg where birds, reptiles, and egg laying mammals are capable of completing their life cycles on dry land.










22. This is a picture of my eye. I have brown eyes, where my mom and sister have green eyes. This is evidence of same trait, different alleles. An allele is a series of different forms of a gene. My sister got the recessive gene, where I got the dominant gene from my dad who also has brown eyes.







23. This is an example of glycogen. Glycogen is the analogue of starch, a less branched glucose polymer in plants. It is a polysaccharide, molecularly similar to starch, constituting the principal carbohydrate storage material in animals and occurring chiefly in the liver, in muscle, and in fungi and yeasts.







24. This is my ear, which is an example of connective tissue. Body tissue that serves to connect or support other tissues or parts.











25. This is my dog. She is an example of a heterotroph. A heterotroph is an organism requiring organic compounds for its principal source of food.
