Sycon Canal System With Diagram

Image
                                     Canal system in Sycon  A sea creature called a sycon, or scypha , is usually found clinging to rocks or other surfaces. These creatures have tube-shaped bodies that open outward with the help of a hole called an Osculum . They have tiny openings called Spiracles and Ostia all over their bodies to let water in. This water flows through canals inside their bodies and comes out through the Osculum, which is a larger opening used for breathing. We'll observe the shape of this canal system, why it is essential for those animals, type of canal system , and  its significance. The Sycon Type Canal system is the unique feature of the phylum Porifera . This system is also known as the  aquiferous canal system . This system supports the significant function of the body like nutrition, respiration, excretion, etc. History Overview -  Gran...

Whittaker's Five Kingdom Classification | Biology Blog

Image
                                   Five Kingdom Classification Early biologists classified all species as either plants or animals. Since this method makes it difficult to research specific creatures, American taxonomist R.H. Whittaker created the five-kingdom classification in 1969. This system divides all organisms into groups based on how they are organized and how they are fed. Important standards for this classification include - The complexity of cell structure i.e. Prokaryotic and Eukaryotic. The complexity of the Organisms body is Unicellular and Multicellular. Mode of nutrition Autotrophs and Heterotrophs. Lifestyle. Phylogenetic Relationship. Based on these criteria, Whittaker classified the living world into the following categories  - Kingdom Monera                 Kingdom Protista Kingdom Fungi Kingdom Animalia Ki...

                                             Aurelia  Aurelia aurita is a type of zooplankton found all over the world. They are see-through and don't have eyes, brains, or hearts. They're usually between 2 to 15 inches wide. Even though they prefer being alone, they get carried together in groups called Blooms by wind and water currents. At night, they look like they're moving through the water like jellyfish, which is why they're sometimes called " jellyfish ".  They have four reproductive organs surrounded by tentacles in their top part. Their body color changes based on what they eat, so they can be blue, pink, or other colors. Let's learn more about Aurelia in detail. Details Of Aurelia Diagram -  Body : The center of the diagram would display the jellyfish's bell-shaped body, often called the " umbrella. " Tentacles : Below the bell, you'd see lon...
