Introduction Carbohydrates are also known as carbs, which are molecules made of sugar. Carbohydrates are one of three main nutrients found in foods and drinks along with proteins and fats. Carbohydrates are broken down into glucose by our body. Glucose, or the blood sugar, is our body’s main source of energy for your body’s cells, […]

Mica is a group of minerals that are both physically and chemically similar to one another in their composition. These are sheet silicate minerals with a nearly perfect basal cleavage and a monoclinic crystal system, which makes them particularly valuable. The mica group consists of 37 different phyllosilicate minerals. Mica crystallises into distinct crystallographic structural

Angiosperms’ distinctive reproductive structure is the flower. The term “flower,” as it is commonly used, refers to a reproductive structure that is distinctive in colour and form. Flowers present a seemingly limitless variety of combinations in terms of colour, size, form, and anatomical arrangement.  They range in size from tiny blossoms to enormous blooms. Individual

In biology, a kingdom is a taxonomic rank made up of smaller groupings known as phyla (or divisions, in plants). Historically, the highest taxonomic rank, or the most broad taxon employed in classifying creatures, is kingdom. However, under Carl Woese’s new three-domain approach, announced in 1990, the domain is the most generic taxon, with the

Introduction Five kingdom features is an important topic but before that one must know about the five kingdoms. Early on, scientists began dividing biological beings into categories. Biologists divide the world into two categories: plants and animals. A wider classification system was developed by biologists like Ernst Haeckel, Robert Whittaker and Carl Woese. The classification

Introduction In the earlier times, all living things were pooled together into two kingdoms. One was the plant kingdom, and the other was the animal kingdom. The animal kingdom was composed of every living thing that used to eat, move, grow to a specific size and then stop growing. On the other hand, the plant

Fibres, which are part of a filiform element, have a transverse dimension and are also found in high length and width ratios. They are made up of macromolecules, which in common language are called polymers. These polymers are monomer-like structures, or they are formed by combining several monomers. They are also found to be chemically

The terms “mean” and “median” refer to two different types of “averages. A measure of central tendency is a single number that attempts to represent a set of data by finding the central location within that set of data. As a result, central tendency measures are also known as central location measures. They’re classified as

The basic two-kingdom classification system, which divides plants and animals into two groups, was ineffective for studying species that did not fit into either of the divisions. Some organisms bear no resemblance to plants or animals. As a result, to classify and study all creatures, a larger system was required to first classify and group

Eukaryotic protists make up the kingdom Protista. Unicelled and less sophisticated in structure than other eukaryotes, members of this varied kingdom are generally unicelluar. On the surface, these creatures are generally classified based on their resemblance to other eukaryotes such as animals, plants, and fungus. Protista  A protist is a eukaryotic creature that thrives in
