Introduction All living organisms possess cells. It is most important structurally, biologically, and functionally. By division of cells, they increase the numbers and form all the structures in the body. There are three essential parts present in a cell, namely the plasma membrane, cytoplasm, and nucleus. Cell organelles are present in the cytoplasm. Different cell organelles that are present in the cytoplasm have different functions. Microbodies are cell organelles that are present both in plant and animal cells. In this tutorial, we will learn about microbodies in depth. What are Microbodies? The term microbody was introduced and discovered by scientists ... Read More

Introduction The animal kingdom is large and extremely diverse. Classifying them is necessary to know and understand in spite of their large size. Classification allows an easier understanding of the complexity, evolution patterns, and interrelationships among animals. Primarily animals are classified based on the presence or absence of vertebral column.Vertebrates are those having a vertebral column and invertebrates are with no vertebral column. Invertebrate phyla include Porifera, Cnidaria, Ctenophora, Platyhelminthes, Nematoda, Annelida, Arthropoda, and Echinodermata. Vertebrate phyla include Phylum Pisces, Amphibia, Reptilia, Aves and Mammalia. Members of phylum Mammalia are called mammals and are the most advanced members of the ... Read More

Introduction A point of connection between two or more bones can be referred to as a joint. The joint helps in movement and provides firmness to the pelvis and skull structures. These joints can show no movement, slight movement, or full movement. Joints can be categorized into synovial joints, fibrous joints, and cartilaginous joints. Cartilaginous joints are the ones that join two or more joints together. Two types of cartilaginous joints exist - primary cartilaginous joints and secondary cartilaginous joints. What are Cartilaginous Joints? Cartilaginous joints are the special type of joints in which two bones are connected by ... Read More

Introduction Every living thing in the biosphere or habitat in which we exist is dependent upon one another for sustenance. Because some plants and animals, as we all know, are unable to make food on their own, they must rely on other plants and animals for nourishment. All animals have unique eating preferences and dietary needs. Animals can be categorised into herbivores and carnivores based on their nutritional needs and eating preferences. What are Herbivores? Those animals that feed on plants or plant matter are referred to as herbivores. They eat plants for their sustenance. Herbivores have different ... Read More

Introduction The muscular organ of the human body known as the heart acts as a pump. The heart pumps continuously from birth to death. The heart, the muscular organ is divided into four-chambers i.e. two upper receiving chambers and two lower distributing chambers. The different parts of the heart include a wall of the heart, four chambers, valves, blood vessels, and the electrical conduction system. Cardiac output is the amount of blood pumped by the heart per minute. In this tutorial, we will learn about cardiac output in depth. What is Cardiac Output? Cardiac output is the amount of blood ...

Introduction Carbon is the most important element and forms the basis of all life found on Earth. Humans, animals, plants, invertebrates, prokaryotes, etc. are mainly made of carbon, hydrogen, and oxygen. It is the main component of DNA, RNA, and various primary and secondary metabolites found in higher and lower organisms. Excess of carbon or absence of carbon can cause a severe impact on the functioning of the entire environment. What is the Carbon Cycle? Carbon cycle is a process of recycling carbon atoms from the atmosphere to earth and then back to the atmosphere. Main reservoirs of carbon are ... Read More

Introduction Complex carbohydrates are consumed by living organisms and they get converted into simple glucose molecules which involve ten significant biochemical pathways. Carbohydrates are a major source of energy in our diet. They are often involved in the formation of different components of a cell as well as performing various other functions. The term sugar may be defined as Carbohydrates that are readily soluble in water and are sweet in taste. They can be broadly classified into 3 major groups- monosaccharide, disaccharide, and oligosaccharide. The monosaccharides can be further subdivided on the basis of the presence of different functional groups ... Read More

Introduction Imagine a deer fleeing for its life as it is being chased to death by a predatory cheetah. The deer runs fast and during this its breathing rate increases, and heart pounds furiously in anxiousness. Its legs move the fastest they possibly can. Such intense physiological responses to an external threat (stimulus) are a part of the deer’s flight-or-fight response, wherein the nervous system, muscular system, and skeletal system work together to respond aptly. Such and other responses including wound healing, defense against pathogens, etc., are made possible only through cellular signaling and communication. How does the body know ... Read More

Introduction Every organism whether single-celled or multicellular is made up of cells. They provide body shape and structure and perform a variety of tasks to keep it running. A cell is the fundamental unit of life. According to Cell Theory Hypotheses, “Cell is the fundamental unit of life that gives everything and is self-sufficient in performing all of an organism's essential activities.” What are Cell Organelles? Images Coming soon They make up a cell and make it operate normally by coordinating and working effectively. Depending on the presence or absence of membrane organelles are of three types having unique structures ... Read More

Introduction All living organisms possess cells. It is most important structurally, biologically, and functionally. By division of cells, they increase the numbers and form all the structures in the body. There are three essential parts that are present in a cell, namely plasma membrane, cytoplasm, and nucleus. The nucleus is a spherical organelle that is located toward the center of the cytoplasm. It is present in eukaryotic cells containing genetic material and takes part in cell division. The cell cycle involves various stages of cell division. In this tutorial, we will learn about the cell cycle in depth. Cell Cycle ... Read More
