Dermal tissue is the outermost layer of plants, analogous to the skin of animals. This layer is more commonly known as the epidermis, the same as our outer layer. They are one of the three types of plant tissues, along with vascular and ground tissue. Just as the skin protects our bodies, dermal tissues perform the same function in plants. They are found covering the younger parts of a plant, including leaves, roots, stems, flowers, fruits, and seeds....
Kepler’s laws of planetary motion are a set of three laws describing the motion of planets around the Sun. German mathematician and astronomer Johannes Kepler published these laws between 1609 and 1619 based on observations made by his mentor, Danish astronomer Tycho Brahe. Although Kepler applied the three laws to planets in the solar system, they can be extended to planets outside the solar system, asteroids, and artificial satellites. These laws are collectively known as First Law, Second Law, and Third Law....
Krebs cycle , named after its discoverer Hans Kreb is an essential part of aerobic cellular respiration in eukaryotes. It is also named the citric acid cycle from the first molecule, citrate, which forms during the reaction. Due to three carboxyl groups on its first two intermediates, it has another name, the tricarboxylic acid (TCA) acid cycle. Prior to the Krebs cycle, pyruvic acid (the product of glycolysis), which has three carbon atoms, is split apart and combined with coenzyme A, forming a two-carbon molecule acetyl-CoA....
Lysosomes are membrane-bound cell vesicles found in the cytoplasm of all animal cells. They were discovered and named by Christian de Duve in 1955. de Duve used lysosomes to describe an organelle containing hydrolytic enzymes capable of breaking down biological polymers such as nucleic acid, proteins, carbohydrates, and lipids. When activated, they function as the cell’s digestive system that destroys invading viruses and bacteria, repairs worn-out cells, and in programmed cell death or apoptosis....
Magnetic susceptibility refers to measuring a material’s ability to become magnetized when exposed to an external magnetic field. It is a property that indicates how easily a substance can be attracted or influenced by a magnetic field. The magnetic response of a material can vary depending on its composition, structure, and temperature. Some materials exhibit high magnetic susceptibility, meaning they can be easily magnetized. In contrast, others may have low or even zero susceptibility....
Membrane proteins are protein molecules attached to a cell’s plasma membrane or the membrane of a cell organelle. About one-third of the proteins found in living organisms are membrane proteins. They regulate the majority of the functions of the membrane that help in cell survival. The positions of amino acids in a membrane protein are based on their polarity: Non-polar (hydrophobic) amino acids associated with the lipid bilayer Polar (hydrophilic) amino acids are found internally and face aqueous solutions Membrane Proteins...

A solenoid is a conductor that is wound into a coil of many turns like a helix. The winding is adequately tight so that each turn is well approximated as a circular wire loop lying in a plane perpendicular to the solenoid’s axis. A solenoid can be used as an electromagnet when the ends are connected to a battery. A current passing through it induces a controlled magnetic field whose direction is given by the right-hand rule....
The first part of the water cycle is of course evaporation and transportation, but I don’t want to focus on that, I want to focus on the 2nd step which is sublimation. Sublimation is when snow or hail, or sleet falls down on a mountain and it quickly turns into water vapor by passing the liquid phase.Now lets skip to the last phase which is RIPC
Active and Passive transport are two important biological transport processes that help to move substances such as nutrients, oxygen, water, and other macromolecules within the cell, along with the elimination of waste products using different and contrasting mechanisms. How is Active Transport Different from Passive Transport Active vs Passive Transport Similarities between Active and Passive Transport Both processes help in the movement of essential substances inside the cell and also in the elimination of waste products...

What are Guard Cells and Where are They Located Guard cells are a pair of bean-shaped cells found in the epidermis of leaves and young stems of plants. They look similar to a kidney and exist in pairs surrounding a tiny gas exchange opening called a stoma. Guard cells help plants to perform photosynthesis, get rid of wastes, and excess water. Guard Cells Diagram Structure They are bean or kidney-shaped cells found on the epidermis of a plant....
What are Leucoplasts Leucoplasts are a type of plastids, which are cellular organelles exclusively found in plant cells. Unlike other plastids, they are colorless, i.e., they do not contain any pigments. So, they have been named leucoplasts, as ‘ leukos ’ in Greek means ‘white’ and ‘ plastos ’ stands for ‘formed or molded’. They are usually found in non-photosynthetic tissues such as endosperm, tubers, roots, bulbs, and seeds. They specialize in storing starch, protein, and lipids in plants....
Magnetic permeability refers to a material’s ability to allow the passage of magnetic field lines. It is a fundamental property that helps determine the magnetic behavior of different materials and quantifies how easily they can be magnetized in the presence of an external magnetic field. Materials with high permeability are considered highly responsive to magnetic fields. In contrast, those with low permeability offer more resistance to magnetization. Formula Magnetic permeability is typically denoted by the Greek symbol μ (mu) and is given by...
Poisson’s ratio measures a material’s deformation when stretched or compressed. It quantifies how much it shrinks or expands in directions perpendicular to an applied normal force. For example, when a rubber band is pulled, it not only gets longer but also becomes slightly thinner. Therefore, in addition to longitudinal elongation, it also experiences lateral contraction. The same happens with many materials, including metals and plastics. To quantify the extent to which a material deforms, we first need to define strain , which measures the relative change in shape caused by an applied force....
All living organisms can be grouped into two types based on their fundamental cell structure. They are prokaryotes and eukaryotes, and the cells they possess are called prokaryotic cells and eukaryotic cells. Prokaryotes vs Eukaryotes Prokaryotes are primitive organisms lacking a nucleus and membrane-bound organelles. The term ‘prokaryote’ is derived from the Greek words ‘pro’, meaning ‘before’ and ‘karyon’, meaning ‘kernel’. Together it means ‘before nuclei’. In contrast, eukaryotes are advanced organisms with a well-defined nucleus and membrane-bound organelles....
An RC circuit is a simple electrical circuit composed of a resistor (R) and a capacitor (C) connected in series or parallel with a power source. Its behavior is governed by the interaction between the resistor, which resists changes in current, and the capacitor, which resists changes in voltage, creating a dynamic response when voltage is applied. As we delve deeper into the functioning of an RC circuit, it is essential to explore the distinct processes of charging and discharging the capacitor, each characterized by its unique response to voltage changes....
What is Receptor-Mediated Endocytosis Receptor-mediated endocytosis (RME), also known as ‘Clathrin-mediated endocytosis’, is a process by which bulk of specific molecules like metabolites, vitamins, hormones, proteins, and also viruses (in some cases) get imported into a cell through binding to a receptor present on the cell surface. These molecules adhere to receptors and enter the cell through the infolding of the plasma membrane, which eventually gets pinched off into a vesicle....
