Respiratory System Definition
Human Respiratory System is a network of organs and tissues that helps us breathe. The primary function of this system is to introduce oxygen into the body and expel carbon dioxide from the body.

Process Of Photosynthesis
At the cellular level, the photosynthesis process takes place in cell organelles called chloroplasts. These organelles contain a green-coloured pigment called chlorophyll, which is responsible for the characteristic green colouration of the leaves. As already stated, photosynthesis occurs in the leaves and the specialized cell organelles responsible for this process is called the chloroplast. Structurally,…

Photosynthesis Equation
Photosynthesis reaction involves two reactants, carbon dioxide and water. These two reactants yield two products, namely, oxygen and glucose. Hence, the photosynthesis reaction is considered to be an endothermic reaction. Following is the photosynthesis formula: 6CO2 + 6H2O —> C6H12O6 + 6O2 Unlike plants, certain bacteria that perform photosynthesis do not produce oxygen as the by-product of photosynthesis. Such…

Site of photosynthesis
Where Does This Process Occur? Chloroplasts are the sites of photosynthesis in plants and blue-green algae. All green parts of a plant, including the green stems, green leaves, and sepals – floral parts comprise of chloroplasts – green color plastids. These cell organelles are present only in plant cells and are located within the mesophyll cells of leaves. Factors Affecting PhotosynthesisPhotosynthesis…

What Is Photosynthesis in Biology?
The word “photosynthesis” is derived from the Greek words phōs (pronounced: “fos”) and σύνθεσις (pronounced: “synthesis“)Phōs means “light” and σύνθεσις means, “combining together.” This means “combining together with the help of light.” Photosynthesis also applies to other organisms besides green plants. These include several prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria. These organisms exhibit photosynthesis just…

Parts of Human Brain
Forebrain – Largest part of the brain It is the anterior part of the brain. The forebrain parts include: Forebrain Function: Controls the reproductive functions, body temperature, emotions, hunger and sleep. Fact: The largest among the forebrain parts is the cerebrum. It is also the largest part of all vertebrate brains. Midbrain: Smallest and central part of…

Where is the Brain located?
The brain is enclosed within the skull, which provides frontal, lateral and dorsal protection. The skull consists of 22 bones, 14 of which form the facial bones and the remaining 8 form the cranial bones. Anatomically, the brain is contained within the cranium and is surrounded by the cerebrospinal fluid. The Cerebrospinal Fluid (CSF) is…

The Human Brain
On average, an adult brain weighs between 1.0 kg – 1.5 kg. It is mainly composed of neurons – the fundamental unit of the brain and nervous system. Recent estimates have suggested that the brain contains anywhere between 86 billion to 100 billion neurons. The brain, along with the spinal cord, constitutes the central nervous system. It is responsible…
