                                             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...

                                        Commensalism  Commensalism is the interaction between two species where one species is benefitted and the other is neither harmed nor benefitted. Mostly this type of phenomenon happened in one larger community and one smaller one. We can understand this by taking some examples like - an orchid growing as an epiphyte on a mango tree. Orchids get shelter and nutrition from the mango tree, while the mango tree is neither benefitted nor harmed.                                                 Sea- anemone has stinging tentacles and the clownfish live among them. The fish get protection from predators, which stay away from the stinging tentacles. The anemone does not appear to derive any benefits by hosting the clownfi...

                                       Skeletal System  In the human being, the skeletal system is consist of a framework of bones and cartilage which provide protection to the soft tissues and cell that is embedded in our body. In an adult, human, have a total number of 206 bones found in ts body. There are two types of Skeletal systems found in the human body known as endoskeleton and exoskeleton . The exoskeleton is ectodermal in origin formed outside the body and is non-living whereas endoskeleton is mesodermal in origin formed inside the body and it is living by nature.   During early embryonic development the endoskeleton is made up of notochord and cartilage but later on, this notochord is replaced by the vertebral column, and cartilage is replaced by bones. The skeletal system is grouped into two principal divisions - Axial Skeleton and Appendicular Skelton. ...

                                     Types Of  Pollination  The transfer of pollen grains from the stigma of a pistil is known as Pollination. Pollination in flowering plants occurs by two methods- self-pollination and cross-pollination.  Self Pollination - Self Pollination involves the transfer of pollen grain from the anther to the stigma of the same flower or genetically similar flower. It is of two types -  Autogamy - Transfer of pollen grains from the anther to the stigma of the same flower is known as Autogamy. It occurs by the three methods -  Self Pollination  showing by A& B and cross-pollination is shown by B & C   Cleistogamy - Some Plants never open to ensure complete self-pollination. This condition is called Cleistogamy. For example - oxalis, viola. Homogamy - Anther and stigma of the bisexual flower of the same pla...
