                                       Kingdom  Fungi 



Introduction - The Fungi are heterotrophic organisms, lacking the ability to produce their own food, as they are without chlorophyll. The term Fungi has been derived from the Latin word meaning -Mushrooms. They can be defined as chlorophyllous organisms with nucleated, somatic bodies and cell wall made of cellulose and chitin or both, and they reproduce sexually as well as asexually. The study of fungi is known as Mycology. Organisms of this group are parasites or saprophytes. It include about 1,00,000 species . They have thallus like structure,i.e., the body is not differentiated.

Habitat -  The fungi grow in multiple habitats. In fact, they grow in every available habitat where organic matter, living or dead is found. Most of them are terrestrial. Some fungi are aquatic. The aquatic fungi are considered to be primitive. Many fungi are found in drinking water. They contaminate both our food and water. They are present all the time in the air we breathe. The fungi prefer to grow in damp, dark and humid places.

Structure -  Fungi are simple thalli like organisms which are not differentiated into root, stem, and leaf-like structures. Their body consists of a thin branched threadlike structure called Hyphae. Many hyphae join together to form a network-like structure called mycelium. In some fungi hyphae are septate, i.e., the septum is not found in their hyphae, such hyphae are called Aseptate.  Aseptate fungi are multinucleated, in such condition, hyphae are called Coenocytic. 
Mycelium

Cells of fungi contain all membrane-bound cell organelles such as ribosomes, mitochondria, endoplasmic reticulum, Golgi complex, etc like other eukaryotic cells but chloroplasts are not found in them. 


Features - 


  • They are either parasites or saprophytes. 
  • They are found everywhere, where organic matter is found. Most of them are terrestrial. Some inhabitant the cells of living organisms and some are aquatic. 
  • The cell wall is made up of chitin, but in some species, the cell wall is made of cellulose. 
  • They absorb food and other substances, either through the entire surface of mycelium or by rhizoids. 
  • Plastids are not found in their cells. 
  • They have three types of reproduction; vegetative reproduction, asexual reproduction, sexual reproduction.
  • They have food in the form of glycogen oil droplets.

Sycon Canal System With Diagram

                                     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 -  Grant, a scientist from Scotland, spent a lot of time studying sponges. He was one of the first to really explain how t

How Many Types of Eggs In Animals

                                             Types of Egg Hello guys! We'll examine a crucial area of zoology in this blog: different varieties of eggs. So let's define reproduction first before moving on to the subject. Reproduction is the biological process in which a parent is responsible to produce their offsprings which may be of their own kind. Reproduction is a must process for every individual for the continuing existence of the species. As we all know, there are many different species on the planet, and each of them has a unique method of egg production and inside the egg they contain yolk . The yolk is composed of proteins, fats, vitamins, and minerals, which are vital for the growth and development of the embryo.  Eggs can be classified into different types based on the amount of yolk they contain. l.  On the basis of the amount of Yolk - Depending on the quantity of yolks, eggs can be  Alecithal / Microlecithal / oligolecithal - The amount of yolk pr

                                             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 long, hair-like tentacles extending outward. Oral Arms : The oral arms are  used for
