Characteristics of Kingdom Protista All single-celled eukaryotes are classified as Protista. On the other hand, the kingdom’s borders are not clearly defined. The phylum Protista is primarily an aquatic one. Plants, animals, and fungi are all connected to this kingdom. Like other eukaryotes, the protist cell body has a very well nucleus as well as […]

A centrosome is an organelle that usually consists of two cylindrical structures. These structures are known as centrioles. Both the centrioles in a centrosome lie perpendicular to each other and form an arrangement like a cartwheel concerning each other. An indeterminate pericentriolar material surrounds centrioles in the centrosome. The two centrioles found on the centrosome

A centromere is a constricted section of a chromosome that divides it into two arms (p) and a long arm (q). The chromosomes first replicate during cell division so that each daughter cell has a complete set of chromosomes. The chromosome is made up of two identical structures termed sister chromatids, which are joined at

The cytoskeleton is a redesigned fibrous proteinaceous framework found in the cytoplasm of the cell. It provides mechanical support to cells. It also assists the cell in maintaining its own form and movement. Microtubules are also called tubulin polymers and are larger than the other two. Their diameter is around 25 nanometers. The main function

Animal cells contain an organelle called centriole which is found in pairs in the cell. They are also present in lower plants but are absent in higher plants. They are located near the nucleus and cannot be seen unless the cell is dividing. They divide themselves during cell division. Its structure is simple, and it

Introduction Plant tissues are supportive and provide strength and support to the plants. Tissues are the fundamental components of any living body, whether it be an animal or a plant. An organism is made up of multiple tissues that come together. Individual cells make up tissues. A tissue is a collection of cells that have

Organisms are classified by their phylum. Cnidaria is divided into four classes: Hydrozoa (hydrozoans), Scyphozoa (scyphozoans), Anthozoa (anthozoans), and Cubozoa (cubozoans) (cubozoans). All cnidarians share a number of traits, which supports the idea of a common ancestor. Cnidarians fascinate both laypeople and scientists due to their symmetrical body forms, varied colours, and sometimes complicated life

The basic lattice arrangements are Bravais lattices. All other lattices can be reduced to Bravais lattices. By translation, Bravais lattices move on a certain basis such that they all line up on the same foundation. There are 14 Bravais lattices in three dimensions: 1. Simple Cubic 2. Face Centered Cubic 3. Body-Centered Cubic 4. Hexagonal

Biological classification is the scientific process of classifying organisms into hierarchical groups and subgroups based on their similarities and differences. Several biologists have contributed to this classification method, which took years for researchers to decide on the most fundamental traits. What is Biological Classification, and how does it work? Biological classification is a logical technique

Biological classification is the scientific approach of categorising organisms and subgroups according to their similarities and differences and arranging the group in a hierarchical order of classifications. Significance of Classification System It is not easy to study each organism; analysing one or two group organisms will help attain adequate information regarding the significant features of
