Flatworm Photo Sensory Behaviors Joshua Krystyniak BIO 218 Fall 2010 Lab: Wednesday 9 a.m. Introduction An organism’s environment can impact it in several different ways a few examples of this are temperature‚ lighting‚ and food sources. Some organisms have evolved certain structures to aid in the sensory of light and dark; one such example is certain members of the class Turbellaria have developed structures called photoreceptors (Pike et al. 1986).

Humans‚ Cnidarians‚ Flatworms‚ and Annelids The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli‚ integrating and processing information‚ and generating output‚ it would be hard to survive without a nervous system; however‚ there are different types of nervous systems in various organisms. Humans‚ cnidarians‚ flatworms‚ and annelids all

The last insect that lives in the tropical rainforest is an army ant. Ants that live in the tropical rainforest will eat The second insect is the Goliath Spider. The Goliath Spider eats things that are larger than them. Such as frogs‚ rodents‚ bats‚ lizards and small snakes. They may eat a bird whenever they feel like it but it’s not a high chance that they will be eaten the most. The Goliath Spider doesn’t have any predators because of how much damage they can do to any type of species. The

parts. The organism attaches its tail-end to the ground and pulls itself forward using its head-end in order to tear itself into two parts. Then‚ each of these parts grows back the missing half‚ producing two new identical planaria. 3. A free-living flatworm ingests its food by opening its mouth‚ a cavity which allows food and water to pass. The food passes into the pharynx‚ a muscular tube near the mouth. The pharynx then pumps the food into the digestive cavity‚ called the gut. The cells in the gut

The phyla that lack organs are: Sponges‚ Jellyfish‚ Roundworm and the flatworm. The sponges have symmetry and the jellyfish is radial. The roundworm and the flatworm are both bilateral symmetry. 2. List all of the Phyla that show cephalization. The Phyla that show cephalization are: Platyhelminthes‚ Nematode‚ Annelida‚ Mollusca‚ Arthropoda‚ and the Chordata. (esu

Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells.

Less often‚ yet more genuine cases of paragonimiasis happen when the parasite goes to the focal sensory system. Although uncommon‚ paragonimiasis has been gained in the United States‚ with various cases reported from the Midwest. Once the determination is made‚ possible treatment for paragonimiasis is accessible from a doctor. Causes- Paragonimiasis is produced by infection by a flatworm. This
