Class 11

The study and description of an object’s exterior shapes are the subjects of morphology, a field of science. It can be applied to the study of language (Linguistics), live organisms (Biology), or the earth’s surface (Geology) in this way (Geomorphology). The term morphé is made up of the Greek words morphé, which means “shape,” and […]

Introduction Cockroaches are creatures with a brown or black body that belong to the phylum Arthropoda, class Insecta. In tropical areas, cockroaches with bright yellow, red and green colours have been seen. They feature a long antenna, legs and a flat extension of the upper body wall covering the head ranging from 0.25 inches to

Introduction Morphology and modifications study the size, shape and structure of animals, plants, microbes and the interactions between their constituent elements. The phrase refers to the general characteristics of a plant’s or animal’s biological structure and arrangement of parts. Morphology and modifications refer to the overall features of a plant’s or animal’s physical structure and

A Cockroach is probably the most loathed insect that ever existed. Cockroaches belong to the phylum Arthropoda. But the main fact is that cockroaches have inhabited the earth for the past 300 million years ago and still continue to be present on earth. Here, in this article we have discussed the external morphology and internal

In 1969, R.H. Whittaker proposed a five-kingdom classification. The five-kingdom system is based on specific characteristics such as nutrition, thallus organization, cell structure and reproduction. The kingdom’s classification resulted in five kingdoms: Plantae (the plants); Fungi (fungus and related organisms); Animalia (the animals); Monera (the prokaryotes); Protista (the single-celled eukaryotes). The Kingdom Monera includes all

Introduction Monocotyledonous stems have lateral branches, the circular stem may exhibit depressed characteristics. The cuticle is thick, the epidermis is single-layered, and epidermal hairs are missing. Multicellular trichomes can be found in the single-layered cuticularized epidermis. The cortex and pith of the ground tissues are not separate. The sclerenchymatous hypodermis is frequent. Endodermis and pericycle

On Earth, living forms are divided into five categories. These divisions are based on nutrition, cell type, structure complexity, the energy obtained, and so on. Monera, Protista, Fungi, Plantae, and Animalia are the five kingdoms. Although both Kingdoms Protista and Monera are made out of single-celled organisms. They are, nonetheless, separate from one another. This article

Introduction Molecular systematics is the discipline of classifying organisms based on differences in protein and DNA in order to make fine taxonomic classifications that are not solely based on morphology. Taxonomy, also known as systematics, is the study of classifying organisms into logically related groups. Historically, taxonomy was performed by examining physical characteristics of organisms

The earthworm is studied under Phylum Annelida of the animal kingdom. They are known as farmer’s friends because they play a significant role in agriculture. The faecal deposit of earthworms is known as worm casting, which increases the fertility of the soil and thus the yield. It also increases soil aeration, infiltration, structure and nutrient

A lipid is any of a number of chemical molecules that are water insoluble.They are energy-storage molecules and chemical messengers that include fats, waxes, oils, hormones, and some membrane components. Lipids are one of the most important structural components of living cells, alongside proteins and carbohydrates. Lipids are a varied category of chemicals that serve
