Genetics is the study of genes, genetic variation, and transmission of traits in organisms. In the 19th century, Gregor Mendel was the first to study genetics scientifically. Mendel observed pea plants to study trait inheritance and gave three fundamental laws of inheritance: the Law of Dominance, the Law of Segregation, and the Law of Independent Assortment. Genetics helps us to diagnose and treat various genetic diseases, improve crop yields, and contribute to our understanding of evolution....
The epidermal tissue system includes several differentiated cell types including epidermal cells, guard cells, subsidiary cells, and epidermal hairs (trichomes). The epidermis tissue system performs numerous functions: such as preventing water loss, regulating gas exchange, secreting metabolic substances, and absorbing water and mineral nutrients...
Collenchyma is a plant tissue composed of living cells with thickened cell walls. It is one of the three main types of ground tissues found in plants, along with parenchyma and sclerenchyma. Collenchyma cells provide mechanical support to the growing parts of plants, such as young stems, petioles (leaf stalks), and the outer layers of leaf veins. The primary function of collenchyma is to provide flexibility and strength to the plant....
Difference Between Lytic and Lysogenic Cycle: Lytic and lysogenic cycles are two distinct pathways that viruses can follow during their replication within host cells. In the lytic cycle, the virus enters the host cell, takes over its machinery, and produces new virus particles, eventually causing the host cell to burst and release the viruses. In the lysogenic cycle, the virus integrates its genetic material into the host cell’s DNA, becoming a hidden passenger....
Disease-causing microorganisms in humans can be of different types such as bacteria, fungi, viruses, protozoa, etc. They enter the bodies of humans, plants, and animals, where they find hosts to inhabit. They rely on the host for nutrition. They start to multiply inside the host or human body and affect multiple cells causing diseases. In this article, you can find the disease-causing microorganisms in human notes....
Difference Between Tracheids And Vessels: Tracheids and vessels are specialized cells involved in water conduction within plants. Tracheids are elongated cells with thick walls, while vessels are tube-like structures formed by fused cells. These contrasting adaptations allow plants to efficiently transport water and nutrients from roots to other parts of the plant....

Haversian canals and Volkmann’s canals are both structures found in bone tissue, but they have distinct differences in terms of their location and function. Given below is a detailed description of both canals....
The human immune system is strange. it is such a complicated system that can’t be imagined. It is a well-developed process in the human body. Whenever any foreign element inserts into the human body, the immune cells start acting. It starts operations on the foreign elements & destroys them within the body. It is a complicated structure. Whenever there is any threat from the foreign element, it is considered as the antigen. The element that is not a part of the body. And the substances that help to destroy the antigen are known as the antibody. The monoclonal antibody is one type of that....
The cell is the smallest fundamental unit in animals. It is where the structural organization begins. Additionally, tissues are made up of a collection of cells with comparable functions. Organs are created when tissues group together to carry out particular tasks. Cells⇢Tissues⇢Organs⇢Organ system....
The stability of proteins refers to the ability of a protein to maintain its folded structure and function under various environmental conditions. The stability of protein structure is important for proper functioning within living organisms. Protein structure dictates how proteins interact with other molecules and perform essential biological processes....
Fertilizers are chemicals that are applied to soil or to plants to supply essential plant nutrients. The fertilizers contain nitrogen, potassium, and phosphorus, all of which are essential nutrients for plants. There are two types of fertilizers: Organic fertilizer is derived from plants and animals and Inorganic fertilizer is derived from chemicals and minerals....
