The main difference between photosynthesis and respiration is that photosynthesis occurs during the day, and breathing occurs during the day and at night. Leaves (and other active metabolic tissues) breathe at night. They use oxygen to release carbon dioxide. Low intensity at dawn and dusk. Therefore, the photosynthesis rate and respiratory rate become equal in […]
Four organic molecules make up all life on Earth. Organic molecules contain carbon and hydrogen atoms chemically attached to long chains, with carbon as the main chain and hydrogen atoms attached to carbon atoms. The ability of these atoms to interconnect allows the creation of countless life-beneficial compounds. All living things require four types of […]
How far the electron microscope, increase structures and functions of the organs? Light microscopes are developed into an electron microscope revolutionized for better understanding of structure a shorter length. The resolving power is high that its detail can is up to in, objects can be magnified greatly without loss of clarity. An electron microscope […]
Embryology is the study of fetal development from fertilization to becoming a distinct embryo or species. Comparative embryology is a comparison of fetal development across species.

The gel-like mucus that fills the space between the extracellular plasma membrane and the central nucleus is called the cytoplasm. All organelles are found in the cytoplasm. The nuclear membrane creates a special environment within the nucleus, in which the thick primary layer is called the nucleus. Cytosol The cytoplasm is divided into transparent liquid […]
Mitochondria have two membranes, one outer membrane and an inner membrane with deep inner folds. The inner membrane is impermeable to most molecules and surrounds the vacuum containing the mitochondrial matrix. Mitochondria are the power plants for cells, which break down nutrients and produce energy. The matrix plays a vital role in power generation because […]

The microscope is an instrument which is used to see very small things that cannot be seen with the naked eye. When we look at something through a microscope, it appears larger. Using it, we can view an object up to 1500 times bigger than its original size. Structure of a Microscope: A light microscope […]
Main Difference Diploblastic vs Triploblastic Dummy cells and trefoil cells refer to two different types of Diploblastic stage. The main cell layer formed during embryogenesis is called the germ layer. Invertebrates, usually three germ layers in the stomach, can be identified. They are the endoderm, mesoderm, and ectoderm. However, animals with more complex structures than […]
The tissues are a group of cells that have the same structure and perform different functions. Tissue comes from the Old French word verb, which means, ” to weave “. There are four types of this in animals, including connective tissue. There are three types of muscle, nerve, and epithelial tissue and plants: vascular, terrestrial, […]

Organs System Biological organs refer to a group of tissues in a living organism that have been adapted to perform specific functions. In higher animals, organs are divided into organ systems. For example, the esophagus, stomach, and liver are parts of the digestive system. Examples of Organs In higher animals, there are usually 10 organs: […]
Spores Definition Spores are the breeding grounds of non-flowering plants, bacteria, fungi, and algae. In fact, eggs are babies, except they do not need parents. Not all forms of life are reproduced through sex. Many bacteria (such as fungi and bacteria) do not multiply in the penis. Instead, they form hard structures called spores, which […]
Kidney stones (also called calculus, nephrolithiasis or urolithiasis). Which are made up of particles of minerals and salts inside the kidneys? Diet, being overweight, certain medical conditions, and some supplements and medications are many causes of kidney stones. Kidney stones can affect any part of the urethra from the kidneys to the bladder. Usually, when […]
Flagella Definition Flagella are viewed as hair-like structures with the help of a microscope for the migration of a cell and the word “flagellum” means “whip”. The flagella have a whip-like appearance and help push cells through the fluid. Some special flagella are used as sensory organs that can change pH and temperature in some […]
Today, scientists divide organisms into five mane groups called kingdom. These states are named Monera, Prista, Fungi, Animalia, and Plantae. Examples of beings related to these states are as follows: Kingdom of living organisms Previously, living organisms were divided into two states: The plant kingdom includes bacteria, fungi, algae, and plants.The animal kingdom consists of […]
