Tissues are groups of cells that have a similar structure and act together to perform similar function. In plants, tissues are categorized into three types: vascular, ground and epidermal. In animals, there are four different types of tissues: connective, muscle, nervous and epithelial.  Organs on the other hand, are structures made up of two or … Read more

Solute And Solvent Meaning A solute is defined as the substance that is dissolved in a solution. A solute can come in many forms. It can be gas, liquid or solid.

A prokaryote is usually a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane bound organelle. Organisms that have prokaryotic cells are unicellular and they include archaea and bacteria. Prokaryotic cells do not have a true nucleus that contains their genetic material as eukaryotic cells do; instead they have a nucleoid region, … Read more

Plant growth regulators can be classified as both primary and secondary metabolites due to their role in plant growth and development. What are Primary Metabolites? Primary metabolites are microbial products produced continuously during the exponential phase of growth and are involved in primary metabolic processes such as respiration and photosynthesis. They include intermediates and end-products … Read more

In Human anatomy, the pelvis, also referred to as bony pelvis is a basin-shaped complex of bones. The pelvis has several important functions. Its primary role is to support the weight of the upper body when sitting and to transfer this weight to the lower limbs when standing. It serves as an attachment point for … Read more

Ester and ether are organic molecules with oxygen atoms. The main difference between ether and ester lies in their structure. An ester group requires two oxygen atoms and two carbon atoms to complete its characteristic structure, while an ether group only needs one oxygen atom and two carbon atoms for its structure. Read this article, to … Read more

What Is DNA? DNA (Deoxyribonucleic acid) is a molecule composed of two chains that coil around each other to form a double helix carrying the genetic instructions used in the growth, development, functioning and reproduction of all known organisms and many viruses. The two DNA strands are also known as polynucleotides because they are composed … Read more

A non-communicable disease (NDC) is a disease that is not transmissible directly from one person to another. The diseases are of long duration and generally slow progression. They include Parkinson’s disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Azheimer’s disease, cataracts and many more others. A communicable disease … Read more

Cerebrum Cerebrum is the principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, (left and right) separated by a fissure. It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in … Read more

What Are Bryophytes? Bryophytes are a group of plant species that reproduce via spores rather than flowers or seeds. Most of bryophytes are found in damp environments and lack specialized water-conducting tissues.  Examples of bryophytes include: liverworts, the mosses and hornworts. Many bryophytes usually have the following characteristics: The sporophytes of bryophytes are unbranched, producing … Read more
