The key difference between fluorescence and phosphorescence is that Fluorescence stops as soon as we take away the light source whereas phosphorescence tends to stay little longer even after the irradiating light source is removed. When a molecule or atom absorbs energy, it can undergo various changes. Fluorescence and phosphorescence are two such processes. In […]

Difference Between Red and Blue Litmus Papers
Red vs Blue Litmus Papers Indicators are a special type of chemicals, which have the ability to change their colors when pH is changing. Therefore, these are known as pH indicators. Some indicators can take different colors to different pH values. For example, pH papers show a range of colors depending on the strength […]
Difference Between LED and OLED
LED vs OLED OLED is a special case of Light Emitting Diodes (LED). When the organic layers are used in fabricating LEDs, they are called OLEDs. Both technologies are widely used in modern displays. They help to reduce the power consumption in a greater scale compared to conventional CRT (Cathode Ray Tube) or LCD […]
Difference Between Vacuoles and Vesicles
The key difference between vacuoles and vesicles is that the vacuoles are large membrane-bound sacs used as storage while the vesicles are small membrane-bound sacs used as storage and to transport inside the eukaryotic cells. A cell is like a bag of chemicals, which is capable of survival and self-replication. The cell membrane separates the […]
Difference Between Pollen and Spore
Pollen vs Spore Diploid spore mother cells give rise to spores. Spores are haploid structures. They are important for reproduction as well as for survival in the unfavorable conditions. Spores are seen as a part of the life cycle of many organisms including plants, fungi, bacteria, algae etc. In plants, depending on the different […]
Difference Between Pollen and Nectar
Pollen vs Nectar Flower is a highly specialized reproductive shoot. A typical flower has 4 whorls, one after the other, on a stalk. The stalk can be short or long. The two lower whorls are not directly involved in reproduction. Therefore, they are called accessory whorls. Upper two whorls are directly involved in reproduction. […]
Difference Between Red Grapes and Green Grapes

Difference Between Photosystem 1 and Photosystem 2
The key difference between photosystem 1 and photosystem 2 is that the photosystem 1 has a reaction centre composing of chlorophyll a molecule of P700 that absorbs light at a wavelength of 700 nm. On the other hand, the photosystem II has a reaction centre comprising chlorophyll a molecule of P680 that absorbs light at […]
Difference Between Membranous and Nonmembranous Organelles
The key difference between membranous and nonmembranous organelles is that the membranous organelles are absent in prokaryotic cells while nonmembranous organelles are present in both prokaryotic and eukaryotic cells. The cell is the basic unit of living organisms. However, there are two types of cellular organizations namely prokaryotic and eukaryotic. One of the key features […]
Difference Between Humic Acid and Fulvic Acid
The key difference between humic acid and fulvic acid is that humic acid is not absorbed by plants whereas fulvic acid is absorbed. Humic acids and Fulvic acids are frequently used as plant nutrient supplements. Normally, a humic substance contains many molecules. Some molecules contain aromatic nuclei with attached phenolic and carboxylic groups. These contribute […]
