The major difference between heterochromatin and euchromatin is that heterochromatin is such part of the chromosomes, which is a firmly packed form and are genetically inactive, while euchromatin is an uncoiled (loosely) packed form of chromatin and are genetically active. When the non-dividing cells of the nucleus were observed under the light microscope, it exhibited the two regions, on the ground of concentration or intensity of staining. The dark stained areas are said as heterochromatin … [Read more...]

Difference Between Pollination and Fertilization
Pollination is a process of transferring of pollens from one flower to another. While fertilization is the process after the successful transfer of pollination, which involves the fusion of male gametes and female gametes of plants. Both of these are the natural process. But only flowering plants undergo the process of pollination, while fertilization is the common process of almost all living being. Continuation of life would not have been possible without the presence of plants, as directly … [Read more...]
Difference Between Inhalation and Exhalation
Inhalation is the process of taking in air containing oxygen, while exhalation is the process of giving out rich containing carbon dioxide. This is the basic process of breathing. Here one breath involves the one complete inhalation and exhalation. So breathing rate varies from person to person and different kind of activity they perform in a day. Though on an average, the breathing rate of an adult is 15-18 times a minute, however, it may increase up to 25 times per minute in case of heavy … [Read more...]
Difference Between Hypothyroid and Hyperthyroid
The condition when the thyroid gland produces less amount of thyroid hormones is called hypothyroid, while the condition when there is the overproduction of hormones by the thyroid gland is called hyperthyroid. The thyroid gland is located in a front portion of the neck and affects almost whole body's metabolic process. The main function of thyroid gland is to store, secrete, and produce hormones especially triiodothyronine (T3) and thyroxine (T4) into the bloodstream that regulates numerous … [Read more...]
Difference Between Phytoplankton and Zooplankton
The basic difference between phytoplankton and zooplankton is that the word 'phyto' is used for the small plants like diatoms and algae and word 'zoo' is used for the small animals like tiny fish, crustaceans, which are the weak swimmers and just move along the currents. The word "plankton" refers to the smallest aquatic plants or animals that float and drift in the limnetic zone of water bodies. Planktons are divided into two categories where one is called as permanent plankton and the other … [Read more...]

Contrary, Non-chordates are the animals without backbone or notochord, this the vital difference between chordates and non-chordates is that the. These animals belong to the different phyla of the animal kingdom. Also being same at the multicellular level, there is a lot of difference between patterns of organization of cells in this kingdom. Lower animals like coelenterates, sponges differ in cellular level of … [Read more...]
Difference Between Homozygous and Heterozygous
Individual organisms carrying two identical alleles (for example RR or rr) are called as homozygous. While individual organisms bear different alleles (for example Rr) are called heterozygous. A homozygous trait is when the same kind of two alleles associate to form a trait. A heterozygous is a trait when different kinds of two alleles associate to form a trait. In this type, dominant and regressive alleles are present in the pair, and the dominant will represent the kind of trait the … [Read more...]
Difference Between Angiosperms and Gymnosperms
Angiosperms and Gymnosperms are divided on the ground of kind of seeds they bear. Angiosperms are those whose seeds are covered inside the fruit. Gymnosperms seeds are called as naked seeds as they are exposed one. In gymnosperms, seeds are developed on the surface of specialized leaves and they are cone-bearing in nature. While the angiosperms plants contain ovary within the flowers and fruits. Angiosperms are found almost in all kind of habitat, right from the grasslands to forest to the … [Read more...]
