    Table 1: Samples 1-5

    Phylum/Division
    Common Feature
    Nutrition
    How does the organism break down and absorb food?

    Sample 1: Chrysophyta
    Food get absorb by diffusion; they absorb food by endocytosis. They break down food by lysosomes

    Sample 2: Annelida
    Food is sucked up by earthworms mouth and gets passed through to earthworms pharynx, or throat. The food passes through the esophagus, and into crop that moistens and stores the food temporarily. If the crop is moistened, it moves to the gizzards and churns the food inside.

    Sample 3: Arthropoda
    Arthropoda have specialized distinct organs working together to break down food and absorb nutrients. For example, a grasshopper has several chambers; A foregut, an esophagus and a crop, where food is moistened and stored. A midgut with gastric ceca, pouches that extend from midgut where digestion take place. (2)

    Sample 4: Amphibia
    Amphibian have sticky tongue at the front of mouth so they can extend out to catch insects. They have alimentary canal( mouth, esophagus, stomach, small and large intestine) where food is digested and absorbed. Stomach makes gastric juices to break down food. Pyloric sphincter muscle controls movement of food from stomach into first part of intestine.
    Liver make bile to digest fats; stored in gall bladder. The pancreas make pancreatic juice to digest food in small intestine

    Sample 5: Aves
    Birds have specialized bills to help them eat and take bites. However, they do not chew food. Birds will swallow whole food. If the food is too large or awkward, they will break it into smaller pieces. Birds can rip or shred food as fruit or prey. They will use their bills to break up harder nuts. (3)

    Circulatory System (Transport)
    How does the organism get what it needs to cells (open, closed, diffusion only)?

    Sample 1: Chrysophyta
    They rely on simple diffusion, which is the passive movement of materials from an area of high concentration to an area of low concentration

    Sample 2: Annelida

    A series of closed vessels is responsible for circulation. The two main vessels are the main pumping structures . In dorsal vessel, the blood moves anteriorly. Oxygen is carried by the respiratory pigment hemoglobing, that dissolve in the fluid portion of the blood.

    Sample 3: Arthropoda

    Arthropod have an open circulatory systems consisting of dorsal heart that collects blood from the body cavity. (2)

    Sample 4: Amphibia
    It has a closed circulatory system where there are 3 chambered heart ( right atrium receives deoxygenated blood from body, left atrium receives oxygenated blood from lungs. The ventricles pumps blood to lungs and rest of the body. It has a double loop blood circulation. The arteries carries blood from ventricles to body cells.

    Sample 5: Aves
    The circulatory system of birds contain four-chambered heart and blood vessels. A large volume of blood will be carried throughout the bird's body by vessels called arteries. Blood is returned to heart by vessels called veins. (3)

    Respiratory System
    How does the organism get oxygen and release carbon dioxide?

    Sample 1: Chrysophyta
    They get their oxygen from the sun and carbon dioxide by a process of photosynthesis where they convert sunlight and C02 into food and oxygen .

    Sample 2: Annelida

    All respiration occurred through the skin. Some earthworm have gills associated with segments which are extension of the parapodia in polychaetes.

    Sample 3: Arthropoda

    The respiration takes place through the body surface by means of gills, trachea, and book lungs. (2)

    Sample 4: Amphibia
    They use gills to breathe. Some breathe through lungs and moist skin called cutaneous respiration. (ex. Frogs)
    Glottis is the opening into the throat and lungs.

    Sample 5: Aves
    The four organs of the birds work together to carry out oxygen to the nostrils, trachea, lungs, and air sacs. The air moves through nostrils, down the trachea and into lungs and air sacs. From lungs, oxygen passes into bloodstream and to body cells. (3)

    Reproductive System
    Does the organism use asexual or sexual reproduction (eggs, seeds, spores, placenta, type of fertilization)?

    Sample 1: Chrysophyta
    They can reproduce sexually, but the normal form of reproduction is cell division or asexual reproduction

    Sample 2: Annelida

    Annelid can reproduce asexually by dividing into two or more pieces or by budding off a new individual.
    Some annelid can reproduce sexually. They were thought to be from two separate sexes that releases ova and sperm into the water via their nephridia.

    Sample 3: Arthropoda

    Fertilization is internal in most but not all groups. Most can lay eggs and the development often proceed with some of metamorphosis.
    (2)

    Sample 4: Amphibia
    Amphibian such ...

    Solution Summary

    Organisms are different from one another based on their taxonomic classification. These classification are associated with nutrition, circulatory system, respiratory system, reproductive system, excretory system, growth and development, and regulation.
