Insects And Invertebrates Characteristics Game online. This is an interactive game in which students will use insects as an example of invertebrates to learn about their characteristics. The game is a multiple choice quiz with a fun component. This game works in the classroom and for homeschooling. Please share.
Living organisms under the kingdom animalia are classified either as vertebrates i.e. having a backbone or invertebrate i.e. not having a backbone. But what does this really mean ?
Most animals that live around us have backbones, but invertebrates do not. Some examples of invertebrates are mollusks, snails, and spiders. They make up about 97% of all animal species, which means invertebrates are found almost everywhere. Invertebrates also differ in their reproductive systems. Some species reproduce asexually, while others reproduce sexually.
Invertebrates do not have head bones, but some have nervous systems consisting of fixed nerves and ganglia. Unlike fish and reptiles, which have a brain and tracheal system, invertebrates do not.
Invertebrates are also classified into different phyla. Most of them are multicellular and have a simple integument. Some are covered with a pellicle, while others have an outer layer of noncellular cuticle. The most conspicuous invertebrates have tentacles or legs that allow them to move from one place to another.
Some invertebrates reproduce sexually. Some species are asexual, meaning that the animal does not produce gametes. In this case, reproduction is asexual, and no fusion of gametes occurs. Fission is a form of asexual reproduction in which the animal divides into two parts. The missing region is then regenerated into a whole organism. The process of budding is another example of asexual reproduction that involves a parent and a budding. In this method of reproduction, new individuals are attached to their mother. These individuals may remain attached to their parents throughout their lives or form large, interconnected colonies.
Invertebrates have a nervous system that allows them to perceive their environment. The simplest form of the nervous system is a network of nerves in the skin that senses touch. However, most invertebrates have a more complex nervous system that includes a brain and a variety of sensory organs. A neural network is an essential component of any organism. It enables the animal to sense its environment and respond to changes.
Invertebrates are the most diverse animals in the world and some of them live in water. The largest living organisms are generally aquatic. The aquatic world is home to an enormous variety of animals that include crabs and lobsters. Arachnids and other invertebrates are very social. They are often able to communicate with each other, although they cannot speak.
Invertebrates are characterized by the absence of internal skeletal components. They have neither a vertebral column nor an internal cartilaginous skeleton. Their bodies are composed of eukaryotic heterotrophic cells. Most invertebrates have a digestive system and a nervous system, which makes them unique in the animal kingdom.
