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
Red Grapes vs Green Grapes Grapes are not climacteric fruits. They are a type of berry. The vines on which they grow are perennial and deciduous. Grapes belong to a genus of fruits known as Vitus. Grapes are an abundant fruit, and it can be found all over the world. Red grapes and green […]
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 […]
Difference Between Elimination and Excretion
Elimination vs Excretion Elimination is a process by which waste and indigestible material are removed from the body. Excretion can be considered as a method of elimination, but it involves only in the removal of metabolic waste. What is Excretion? Excretion is the process by which wastes produced in the body are removed from […]
Difference Between Convergent and Divergent Evolution
The key difference between convergent and divergent evolution is that the distinct species that do not share a common ancestor show similar traits in convergent evolution while the species that share a common ancestor show different traits and separate into different forms in divergent evolution. When considering living organisms, we can define evolution as the […]
Difference Between Cacti and Succulents
Cacti vs Succulents The main problem that plants growing in dry and hot environments face is the excessive water loss due to transpiration. An important adaptation shown by cacti and other succulents to overcome this problem is their Crassulacean acid metabolism (CAM). CAM plants open their stomata at night capturing carbon dioxide and close […]
Difference Between Litmus Paper and pH Paper
Litmus Paper vs pH Paper Litmus Paper Litmus paper is an indicator, which can be used to determine acidic and basic solutions. Normally this comes as a paper stripe. Mixture of water-soluble dyes extracted from lichens like Roccella tinctoria are absorbed into filter paper stripes to make litmus paper. In this mixture, there are […]
