Get Best Results with Biology Assignment Help

We may define biology as the field of sciences that comprises the study of the living world; it focuses mainly on the living world's structure, functions, and working. The term biology is composed of two Greek words, "bios" meaning "leaving" and "logos," meaning "knowledge." Biology is a very vast field that encompasses a lot of other branches. However, most of the students take up biology as a profession, pursue research in biology, get different biology assignment topics, and need biology assignment help. NeedAssignmentHelp has biology theory experts who help you with biology questions and give all the biology assignment answers to the students.

Even though biology is a broad field and is more complex in its theories, many concepts of this discipline consolidate into one coherent area. Some ideas of this particular field of science remain undeniably constant with every new research. The chief principle of biology lies beneath the basic structural unit of life known as the cell.

Further Trifurcations of Biology

The living beings on earth are only three major types; plants, animals, and highly minute microorganisms. Biology consists of broad disciplines, namely, botany, zoology, and microbiology. NeedAssignmentHelp provides biology assignment help for each of the below-mentioned disciplines of biology theory. Also, we have a team of highly skilled experts who are available almost every time to provide you assistance with any biology questions, making you capable enough of deducing the biology answers.

Classifications of Biology

• Botany – The term botany comes from the Greek word "botanē," which means "grass." It is the branch of biology which includes the study of the plant world. It focuses on the study of structure, embryology, anatomy, morphology, distribution, and the classification of plants. Botany is yet another vast field embodying plants' analysis, including trees, shrubs, small plants, ferns, etc. It is sometimes referred to as plant biology or phytology too. Botany interests many students, and today, botany researchers study almost 410,000 species of plants present on the land. Also, it is quite an emerging discipline in the field of research.
• Zoology – This branch of biology involves studying the structure, function, morphology, anatomy, physiology, behavior, reproduction, embryology of the various animals in the ecosystem. It focuses on studying animal behavior, and the working of the animal body referred to as animal biology. The term zoology comes from the ancient Greek word "zōion," which means animals, and hence, it governs mainly the study and research upon the animal kingdom specifically.
• Microbiology – This branch primarily deals with the organisms in the living world, which are not visible to the naked eye. Microorganisms are visible only under specialized microscopes of different types like compound, straightforward microscopes, light, and electron microscopes. Microbiology includes the study of microbes which include bacteria, protozoa, viruses, algae, and fungi. In other words, microbiology is the collaborative study of each type of microorganism. Also, all these disciplines are studied separately too.

Different Branches of Biology

Biology is a vast field encompassing many disciplines inside it. Mentioned below are some major biology branches that interest most students all over the world.

1. Anatomy is the branch dealing with the study of the internal structure of living organisms.
2. Bacteriology is the branch of biology which deals with the study of bacteria.
3. Cell biology deals with the study of the smallest and the structural part of organisms; cells.
4. Ecology is the branch of biology which deals with the relation of living organisms with one another.
5. Embryology is the branch of biology that deals with the study of the embryos of various living organisms.
6. Hematology is the branch of biology which deals with the study of the blood and the blood-forming compounds.
7. Molecular biology is the discipline of biology that deals with studying living organisms at the molecular level.
8. Pathology is the study of the disease-causing microorganisms present in the environment.
9. Biotechnology is the field of biology that deals with the manipulation and genetic changes in typical living organisms to produce various products.
10. Genetics is the branch of biology which deals with the study of genes and the structure and functions of genes.
11. Medicine is also a branch of biology that mainly focuses on the deduction of various theories and laws to treat the various illnesses of the diseased body of living organisms.

Biological Classification

The biologists and the researchers have classified the organisms based on their similarities; these similarities include morphological, behavioral, or genetic similarities. Biology is the study of living beings. We have millions and trillions of organisms on the earth today; hence, to make the study of living beings easier, scientists and researchers have sub-divided the living beings according to biological classification. Below mentioned are the seven ranks of the natural variety.

7 Ranks of Biological Classification

• Species – The species is the most basic unit of classification and the minor taxonomic rank. A species includes a group of closely related organisms that can reproduce within them. It also constitutes the highest number of organisms.
• Genus – It is a rank higher than the species according to the biological classification. It includes the organisms of the closely related species. A genus comprises many species in itself, and it has fewer organisms than species.
• Family – A family in biology refers to the hierarchical rank, which is a step higher than the genus. This rank includes a group of organisms that are closely related based on the genus. A family encompasses several genera.
• Order – The taxonomic rank is higher than the family, and it includes the organisms of the closely related families. The declaration contains several families. The botanist Augustus Rivinus first introduced the term.
• Class – Class is the next taxonomic rank according to which the organisms divide—the organisms of closely related orders arranged in a single class. A taxonomist determines the composition of every class.
• Phylum/Division – The second taxonomic rank is the Phylum of the division. The term phylum is for the animals, while the division is for the plants. Further, these five kingdoms mentioned above divide into different Phylum and divisions based on their characteristics.
• Kingdom – The kingdom is the highest rank of the taxonomy; biology includes five primary domains: Plantae, Animalia, Fungi, Algae, and Bacteria.

In conclusion, each of the above ranks is individually called the taxa. According to these taxa, the complete process and the science behind the classification of the organisms is taxonomy.

Problems Faced by Students in Biology Homework Assignments

There are many universities and colleges worldwide that offer various courses in different fields of biology. Different universities follow different study patterns and provide other biology assignment topics to the students. Biology theory is a complex subject and requires a lot of concentration and hard work. However, students often fail to get enough time to complete biology assignments as there is a lot to memorize in biology. Students fall in managing time for both the study and the completion of the biology assignment. That is where NeedAssignmentHelp provides the students with biology assignment help.
