Down Syndrome

Down syndrome or Down’s syndrome is the defect in the child who is born with an additional copy of their 21st chromosome, therefore it is also called ‘trisomy 21’. This syndrome has impacts on the development of the child which is physically as well as mentally. People with Down syndrome have a short life expectancy, […]

Diabetes and Its Types

Such a clinical condition which is marked by rising in blood glucose level (hyperglycemia). It is also known as ‘Diabetes Mellitus‘. In this condition, the hormone ‘Insulin’ responsible for regulating the blood sugar level, is either not sufficiently produced by the pancreas or when the body is unable to use it (insulin) effectively, it may […]

Immunoglobulins and Its Types

When we discuss our Immune system, the two terms then strike our minds are the ‘antigen’ and the ‘antibody’. Antigen as we all know is the foreign particle that invades our body’s mechanism and thus tries to weaken our immune system. On the contrary, Antibodies are present in one’s body and work as the defender […]

Tropisms: Movements in Plants

In physiology, such changes or actions that incites the living being or part of it to quickens its actions or any functional activity is known as stimulus. Likewise the animals or other organisms, plants also respond to the stimulus or any changes in the environment. The only difference is that animals move from one place […]

Immune System

In general, the natural protection provided by the body against certain illnesses or diseases is known as the word ‘immune‘. So, a complex network of cells that work to protect one’s body from infectious diseases and foreign invaders that may harm the body is known as the immune system. The immune system is made up […]


What is Photosynthesis? When green plants and certain other organisms (bacteria, algae, and protistans) convert light energy into chemical energy is known as Photosynthesis. In this process the most important source of light – sunlight is captured by the green plants, and along with the use of carbon dioxide, water, and minerals it gets converted […]

Blood Types or Blood Groups

While everyone’s body constitutes the same elements, but then too we all vary from one another, the same is the matter of blood present in our body. There are mainly eight types of blood groups that are been inherited from the parents. The average amount of blood present in one’s body is around 4-6 liters. […]

Plant Tissues and Its Types

When the similar cells get aggregate to form the organized structure to carry out the specific function is known as tissue. Likewise the animal tissues, plant tissues also consist of numerous multicellular cells. A tissue is the collection of the functionally and morphologically similar cells and their core materials. Plant tissue provides the mechanical strength […]

Eukaryotic Cells

Prokaryotes are simple in structure with no specific organelles, just like the single cabin; whereas eukaryotic cells have well-defined organelles with each having specific roles to perform, likewise the beautiful home with separated rooms. Eukaryotic cells are known for proper compartmentalization. These cells have true and membrane-bound nucleus and other membranous organelle and each exerts […]

Animal Tissues and Its Types

When the smallest unit of life i.e. cells are grouped together they form tissues. These groups are cells that are functionally and structurally similar and unite to perform specialized functions. Tissues are present in multicellular organisms, but not in unicellular, and even simple species of multicellular species like sponges, tissues are not well developed. But […]
