Structural Organisation in Animals and Plants

Several species can grow quickly under specific conditions, causing water blooms or red tides that discolour the water and may harm fish and other organisms. Some dinoflagellates release toxins that are among the most harmful bacteria known. Characteristics of Dinoflagellates: Dinoflagellates are single-celled eukaryotic animals that belong to the kingdom Protista and the phylum Dinoflagellata. […]

Introduction Cockroaches are the most primitive living winged insects. They belong to the class Insecta of Phylum  Arthropoda. They are mostly found in damp places rich in organic components and in human spaces like stores and hotels. They are omnivores and feed on bread, fruit, cloth and even dead bodies. They are considered serious pests

It is difficult to tell the difference between thorns and spines based solely on appearance because they are nearly identical. Thorns and spines are both parts of the plant. Although they have a similar appearance, they are not the same. The basic similarity between thorns and spines is that they are both plant parts, but

Monerans differ from eukaryotic animals due to the structure and chemistry of their cells. Because they are prokaryotes, they lack the distinct nucleus and membrane-bound organelles (specialised cellular elements) of eukaryotic cells. Despite the fact that DNA transfer between bacteria is frequent and forms the basis of recombinant DNA technology, bacteria mostly reproduce through transverse

Larva and pupa are two life stages found in insects. These stages are sequential, but there are many differences between them. Metamorphosis is the process of going through several stages like this. It is a common characteristic of modern insects. Invertebrates are the only invertebrates with wings that allow them to fly. Because of this

Joints We can define a joint as a location at which two or more entities are joined to one another. A joint is a location in the human body where two bones are joined together in some way. A joint is a junction, or to put it another way, it is a strong link that

This was once the group’s defining feature, however protostomes have recently been discovered to have deuterostomy as well.Because their coelom grows through enterocoely, this group is also known as enterocoelomates. Chordata (vertebrates), Echinodermata (starfish), and Hemichordata are the three primary clades of deuterostomes (e.g. acorn worms). The Bilateria, which includes Protostomia and its outgroup Xenacoelomorpha,

There are five to ten nectar glands, some of which are connected. Five groups (one at the base of each bracteole) of extremely reduced male flowers, each consisting of a single anther on a stem, stand in the centre at the base of the involucre, consisting of an ovary on a short stem with pistil,

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
