9. Dominant vs. Recessive Phenotype

A phenotype is a physical appearance or an observable characteristic of an organism as the result of their genotype and their interaction with the environment. A dominant allele produces a dominant phenotype and the recessive allele produces a recessive phenotype. However, if a dominant allele is crossed with a recessive allele, the result will be a dominant phenotype because it surpasses the recessive allele. The brown eyes in the picture are the dominant phenotype and the blue eyes are the recessive phenotype. If brown eyes were crossed with blue eyes, it would result in brown eyes because it will dominate over the blue.

10. Ectotherm

Ectotherm usually refers to cold blooded organisms. They depend on the environment for body heat because they cannot regulate their own. When the environment’s temperature changes, so does the organism’s. If the environment experiences big temperature changes, the organism’s life can be in danger. The fish in the tank is cold blooded, so therefore their body temperature varies with the temperature of the water.

11. Epithelial Tissue

My hand is an example of epithelial tissue because it is covered with it. Epithelial tissue, also known as epithelium is sheets of body tissue that covers and lines the external and internal surface of the entire body. It is made up of tightly and densely packed cells. Epithelial tissue is categorized according to how many cell layers it has and the shape of the cells. The epithelial tissue helps my hands protect, sensate, excrete, diffuse, and absorb. Epithelial tissue is considered as avascular because it lacks blood vessels.

12. Exoskeleton

Exoskeleton is outer covering that protects and supports an animal’s body. The turtle in this picture has a shell which is an example of an exoskeleton. For turtles, their shell protects their inner organs such as muscles and other soft tissues. The exoskeleton also provides a measure of safety from predators. They can quickly dive into their shell when they sense danger.

13. Fermentation

Grapes turning into wine is an example of fermentation. Fermentation is a cellular process that does not require oxygen. It is changing carbohydrates into alcohols, carbon dioxide or organic acids using bacteria or yeast. Because grape skin contains natural bacteria and yeast, it is fermented with its skin. After the grapes have been made into grape juice, if it is put at the right temperature, then the yeast turns the sugar in the grape juice into alcohol and carbon dioxide. That is the process of grape fermentation.

14. Flower Ovary

The flower ovary is not pictured here but it is bulb shaped and located at the lowest part of the pistil. The ovary is a female part of the flower and contains one or more ovules, female eggs. It protects the ovules of the flower while the ovules develop into seeds. The ovary produces fruits after it has been fertilized.

15. Frond

Frond is a large leaf with many divisions. Ferns in this picture is a good example of frond because its leaves have many divisions within it. Fronds usually refer to ferns, but it can also describe cycads and palms. The stalk of the fern is called the stripe and where the individual leaves are located is called the rachis. The blades of ferns can be classified into being simple, pinnatifid, or pinnate. Ferns reproduce with spores that are under their leaves.
