Biology

Biology is a vast discipline that deals with the study of living beings and their vital processes, that deal with the physicochemical aspects of life.

Biology is a natural science that utilizes different structural and functional concepts for the differentiation of living beings from non-living beings.
At present times, as a result of cross-disciplinary research, other disciplines like chemistry, physics, computer science, and medicine have been integrated with biology, resulting in areas like biochemistry, biophysics, biomedicine, and bioinformatics.
Biology is further divided into separate branches for the convenience of study, even though all of these branches are interrelated to one another.
Biology is separated into botany (the study of plants) and zoology (the study of animals), morphology (structure), and physiology (function).
Living beings have been divided into different kingdoms, phylum, classes, orders, and genus to make the identification and studies related to different organisms more feasible.
Traditionally, biology was only associated with the structure and function of living beings.
With time, however, biology deals with the fundamental levels of life, resulting in a separate discipline termed, molecular biology.
Biology has now been developed into modern biology which is based on certain foundations like cell theory, evolution, genetics, homeostasis, and chemical energy.
Biology defines cell as the fundamental unit of life, which is common in all living beings, microscopic, and macroscopic.
Besides, other concepts like evolution and genomics further help in understanding the origin, evolution, and relationship among living beings.
Genetics is another component of biology that helps in the differentiation of living beings based on their genomic composition.
Homeostasis is another crucial unit of biology which suggests that all living organisms maintain a constant internal environment.
Non-living parts of the world like the air, water, and soil have been closely related to the living world, which creates a close relationship between biology and the environment.

Trophic level- Definition, food chain, food web, pyramid, examples

February 5, 2021 by Anupama Sapkota

Trophic level Definition Trophic level is the position within a food chain that is occupied by a group of organisms in an ecosystem. The classification of organisms into the different food chains is based on their feeding behavior. Trophic level is a step in the nutritive series of food chains which in some cases might form a complicated path called …

Eutrophication- Definition, Causes, Types, Process, Examples

February 5, 2021 by Anupama Sapkota

Eutrophication Definition Eutrophication is the condition of a gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in a water body resulting in excessive plant and algal growth. Eutrophication is one of the most widespread challenges faced by freshwater systems and also has a long history in terms of water management. It is a natural process that …

Monocot vs Dicot Seed- Definition, Structure, 10 Differences, Examples

February 4, 2021 by Anupama Sapkota

Definition of Monocot Seed Monocot seeds are defined as seeds that consist of a single (mono) embryonic leaf or cotyledon. The structure of the seed and the number of cotyledons present in the seed are the most important characteristics that allow the differentiation of monocots and dicots. The seed pod of most monocots is trimerous (exist in three parts) as …

Monocot vs Dicot Flower- Definition, Structure, 6 Differences, Examples

February 4, 2021 by Anupama Sapkota

Definition of Monocot Flower Monocot flowers are condensed shoot regions that are specialized for the function of sexual reproduction. The most definitive characteristic of monocot flowers is that these flowers usually have flower parts that occur in threes or multiples of threes. The observation of flowers and their parts; thus, can be used as a method to differentiate between monocot …

Monocot vs Dicot Stem- Definition, Structure, 22 Differences, Examples

February 3, 2021 by Anupama Sapkota

Definition of Monocot Stem Monocot stem is a circular-shaped hollow axial part of the plant which gives rise to nodes, internodes, leaves, branches, flowers with roots at the basal end. The size of stems varies in different species of monocots, but the size is barely ever as large as dicots. Monocot stems are herbaceous as they lack secondary growth due …

Monocot vs Dicot Roots- Definition, Structure, 18 Differences, Examples

February 2, 2021 by Anupama Sapkota

Definition of Monocot Root Monocot roots are fibrous or adventitious roots consisting of a wide network of thin roots and root fibers that originate from the stem. Monocot roots are highly variable depending on the plant species and the age of the plant. But most of the monocot plants are herbaceous with weak cambium that cannot hold woody tissues. The …

Monocot vs Dicot Leaves- Definition, Structure, 13 Differences, Examples

February 2, 2021February 1, 2021 by Anupama Sapkota

Definition of Monocot Leaves Monocotyledonous leaves are narrow and elongated with parallel venation, which is often used to distinguish monocotyledonous plants from dicots. Monocot leaves are isobilateral as both the surfaces of the leaves are similar to the same coloration. The primordial monocot leaves consist of a proximal leaf base or hypophyll and a distal hyperphyll. The hyperphyll is the …

Feedback Mechanism- Definition, Types, Process, Examples, Applications

January 21, 2021 by Anupama Sapkota

Feedback Mechanism Definition The feedback mechanism is the physiological regulatory system in a living body that works to return the body to the normal internal state or homeostasis. These mechanisms are also found in nature in different ecosystems and animal groups. The feedback mechanism in the living system occurs in the form of a loop which assists in the maintenance …

Connective Tissue- definition, structure, cells, types, functions, diseases

January 5, 2021 by Anupama Sapkota

Connective Tissue Definition Connective tissue is one of the tissue systems in animals composed of different types of cells, all of which work together to provide internal support, adhesion, and cohesion between tissues to form organs and systems. The cells of connective tissue provide a matrix that gives metabolic support to cells as well as a medium for the transport …

3D Bioprinting- Definition, Principle, Process, Types, Applications

December 16, 2020 by Anupama Sapkota

What is 3D Bioprinting? 3D Bioprinting is the method of printing biomedical structures with the use of viable cells, biological molecules, and biomaterials. In simple words, 3D bioprinting is the deposition of biological material in a layer-by-layer fashion to create 3D structures like tissues and organs. Bioprinting is considered a part of additive manufacturing that involves the formation of materials …
