Labelled Diagram Of Leaf

Hello Students!    

As you know leaves are an important part of the plant that carries out photosynthesis to help the plant to exist. Photosynthesis is the process in which light energy is converted into chemical energy i.e.,  plants use carbon dioxide and water and convert them into oxygen and Glucose which is further use by the plants in the form of food.

 But do you know how the leaf is consists of?  

The plants have some thin, flat organs present at the lateral side of each node known as Leaves.

Parts of a leave -  A leaf consist of some basic structure like leaf base, petiole, and lamina. 

  • Leaf Base -   This is the part where a leaf attaches to the stem. Leaf base has two small leaf-like structures called stipules.

  • Petiole -    petiole is long, thin, stalk that links the leaf blade to the stem. 

  • lamina -- Lamina is also known as Leaf Blade. It is the green , flat surface of the leaves . It consists of small branches veins that run along the middle of the lamina is called Midrib. The Midrib divides the surface of the leaf into two- veins and veinlets. These veins and veinlets give rigidity to the leaf blade and help in the transportation of water and other substances.

                                     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

                                             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

                                             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
