The species characterized by animals with a segmented body is the annelids. Segmentation is a process of cell division in which the animal’s body plan becomes more complex. This allows for greater mobility and flexibility and increased surface area for gas exchange and nutrient absorption. For knowing more details read here Which Phylum is Characterized by Animals That Have a Segmented Body?
Animals in the Phylum Arthropoda are characterized by having a segmented body. This means that their bodies are divided into distinct sections or segments. Each segment has its specific function, and all segments work together to allow the animal to move and function properly.
Arthropods include insects, spiders, crabs, and lobsters.
Which Phylum is Characterized by Animals That Have a Segmented Body Quizlet?
The species that animals characterize with a segmented body is the Arthropoda. This phylum includes insects, arachnids, and crustaceans. The segmented body allows these animals to move quickly and efficiently.
Each segment has a specific function, which helps the animal to survive in its environment.
Which Phylum is Characterized by Animals With Segmented Body And Jointed Appendages?
The species characterized by animals with a segmented body and jointed appendages are called the Arthropoda. This phylum includes insects, spiders, crabs, and lobsters. The body segmentation allows these animals to move very efficiently, and the jointed appendages give them a great deal of talent.
Which of the Following Organism Has a Segmented Body?
Many animals have segmented bodies, including insects, arachnids, and some annelid worms. Segmentation is a process of cell division in which the body is divided into repeating units. This type of body organization provides several advantages, such as an increased surface area for gas exchange and improved strength and flexibility.
In addition, segmentation allows for the regeneration of lost body parts.
Do Molluscs Have Segmented Body?
Mollusks are a very diverse group of animals that includes snails, slugs, squid, and octopuses. Most mollusks have a segmented body, meaning they are divided into sections. This is most evident in how their guts are arranged, with each section having its separate opening.
However, not all mollusks are segmented. For example, chitons have a single continuous shell, and some sea slugs lack any shell at all.
The Water Vascular System of Echinoderms
Echinoderms are a diverse marine animal group, including starfish, sea urchins, and cucumbers. They are characterized by their five-pointed symmetry and their water vascular system. The water vascular system is a network of fluid-filled tubes that extends throughout the body and functions in locomotion, feeding, and gas exchange.
The primary component of the water vascular system is the madreporite, a small pore on the body’s surface. Water enters the madreporite and passes through a series of interconnected chambers before reaching the central ring canal. The ring canal encircles the mouth and provides an exit for water used for locomotion or feeding.
Tiny tubes called podia extend from the ring canal to each of the five arms. Podia are used for locomotion by coordinated contraction and expansion of their muscles. The water vascular system also aids feeding by creating suction that pulls food particles into the mouth.
Sea urchins use their sharp spines to scrape algae off rocks, while sea cucumbers feed on detritus (dead organic matter). Starfish are predators and use their tube feet to capture prey before drawing it into their mouths with suction. In addition to locomotion and feeding, echinoderms rely on their water vascular system for gas exchange.
Oxygen diffuses from the surrounding seawater into the fluid within the tube feet and then circulates through the body via diffusion. Carbon dioxide produced by cells diffuses out through open pores in the echinoderm skin called spiracles.
Which of the Following Combinations of Phylum And Description is Incorrect?
There are a few different ways to classify animals, but one of the most common is by phylum. Here are some of the most common animal species: -Chordates (includes vertebrates)
-Arthropods (includes insects) -Mollusks (includes snails and squid) -Annelids (includes worms)
-Echinoderms (includes starfish and sea urchins) -Cnidarians (includes jellyfish and corals). Now, let’s see if you can match the correct description with the right species!
Animal That Has Segmented Body Examples
There are quite a few animals that have segmented bodies. Their bodies are divided into distinct sections, each with its function. Segmentation is often used to help an animal move more efficiently or to protect vital organs.
Here are a few examples of animals with segmented bodies: 1. Worms – Worms are perhaps the most well-known example of an animal with a segmented body. Their long, thin bodies comprise many small sections, each containing its organs.
This allows them to squirm and wriggle through tight spaces easily. 2. Centipedes – Centipedes also have long, segmented bodies, but theirs are much different from worms. Each section of their body has a pair of legs attached to it (hence the name “centipede,” which means “100 legs”).
These legs help them move quickly across the ground as they hunt for prey. 3. Millipedes – Like centipedes, millipedes also have segmented bodies with legs attached to each section. However, as centipedes do, they only have two pairs of legs per section instead of three.
Millipedes move slower than centipedes but make up for it by curling into a tight ball when threatened, protecting their vulnerable underside. 4. Crustaceans include creatures like crabs, lobsters, and shrimp. They all have hard outer shells (or “carapaces”) that protect their softer inner body parts (including their segmented abdomens).
This tough exterior helps them survive in some pretty hostile environments like the bottom of the ocean!
Select the Correct Statement(S) About Animal Body Plans.
Most animals can be classified into one of three basic body plans: the acoelomate, the pseudocoelomate, or the coelomate. Each body plan reflects a different level of organization and complexity in animal anatomy. Acoelomates are the simplest type of animal, lacking a true coelom—a fluid-filled internal cavity lined by mesoderm (embryonic tissue).
Instead, they have a solid mass of mesoderm sandwiched between an inner layer of ectoderm (outer embryonic tissue) and an outer layer of endoderm (inner embryonic tissue). Most flatworms are acoelomates. Pseudocoelomates have only a partial coelom—their bodies are partially filled with fluid but not lined by mesoderm.
Their pseudocoel contains some fluid but is surrounded by ectoderm on the inside and endoderm on the outside; there is no lining of mesodermal cells. Many roundworms are pseudocoelomates. Coelomates possess a true coelom completely lined by mesodermal cells; it lies between the animal’s ectoderm and endoderm.
The space within the coelom provides room for organs to move around during contraction and other body movements; it also acts as a hydrostatic skeleton, resisting changes in shape when external forces are applied to the body. Most annelids, mollusks, arthropods, echinoderms, and chordates are coelomates.
Which of the following is a Characteristic of Cnidarians?
Cnidarians are a type of animal that includes creatures like jellyfish, corals, and hydroids. They are characterized by their possession of cnidocytes, cells containing stinging organelles called nematocysts. Cnidarians have two main body forms: the medusa, typically a free-floating form, and the polyp, which is attached to a substrate.
Some cnidarians are capable of changing between these two forms.
Of the Annelid Classes Below, Which Have Externally Segmented Bodies
Of the Annelid Classes Below, Which Have Externally Segmented Bodies? As you probably know, annelids are a paraphyletic group of animals that includes earthworms, leeches, and segmented worms. One defining characteristic of annelids is that they have segmented bodies.
However, not all annelids have externally segmented bodies. So which classes of annelids have externally segmented bodies? The answer is: Earthworms and leeches belong to the class Clitellata, which has internally segmented bodies.
The other two classes of annelids, Hirudinea and Oligochaeta, have externally segmented bodies. So there you have it! Of the four main classes of annelids, only two have externally segmented bodies.
Select All of the Following That is Characteristic of Animals.
Animals are multicellular, eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, can move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there may be over 7 million in total.
Animals range in length from 8.5 millionths of a meter to 33.6 meters (110 ft) and have complex interactions with each other and their environments, forming intricate food webs.
Which of the Following Combinations of Phylum And Description is Correct?
There are many different species of living things on Earth, each with unique characteristics. When identifying an organism, it is important to know which species it belongs to determine its features correctly. Here is a list of some common phyla and their descriptions:
-Arthropoda: This species includes animals with jointed appendages and exoskeletons, such as insects, spiders, and crabs. -Chordata: This species includes animals with a backbone or spinal cord, such as mammals, reptiles, and fish. -Mollusca: This species includes animals with soft bodies and often hard shells, such as snails and octopuses.
-Annelida: This species includes animals that are segmented worms, such as earthworms and leeches. -Echinodermata: This species includes animals that have spiny skin and often live in the ocean, such as starfish and sea urchins.
The species that is characterized by animals that have a segmented body is the Arthropoda. This includes animals such as insects, spiders, and crabs. The segmentation allows these animals to move more easily and to be able to change direction quickly.
