The key difference between plasmid and chromosome is that the plasmid is a circular double-stranded extra-chromosomal DNA structure of bacteria while the chromosome is a well-organized thread-like structure that contains genomic DNA tightly coiled with proteins. The bacterial cell contains a chromosome and several extra-chromosomal DNA circles called plasmids. Bacterial chromosome contains the genomic DNA […]
Difference Between Prokaryotic and Eukaryotic Ribosomes
The key difference between prokaryotic and eukaryotic ribosomes is that the prokaryotic ribosomes are 70S particles composed of 50S large subunit and 30S small subunit while the eukaryotic ribosomes are 80S particles composed of 60S large subunit and a 40S small subunit. Prokaryotes and eukaryotes are two major groups of living organisms that differ from […]
Difference Between Spermatogenesis and Spermiogenesis
Spermatogenesis vs Spermiogenesis An important objective in the life of all the living beings is the reproduction and making sure that their kind will survive in the future. In order to reach that objective successfully, the sexual reproduction is instrumental, and the gametes from males and females are mixed with each other to produce […]
Difference Between Gross Primary Productivity and Net Primary Productivity
Gross Primary Productivity vs Net Primary Productivity Have you ever wondered how would food come into our hands? Animals and other consumer organisms cannot eat or consume solar energy, but photosynthetic plants and algae are greatly capable of doing so. It sounds sensible that the production of food takes place in plants by using […]
Difference Between Bryophytes and Ferns
The key difference between Bryophytes and Ferns is that the bryophytes are nonvascular plants having a dominant gametophyte generation while the ferns are vascular plants having a dominant sporophyte generation. Through the evolutionary process, earth colonized with vascular plants and non-vascular plants which are called primitive land plants. Among these primitive land plants, bryophytes are […]
Difference Between Gross Primary Production (GPP) and Net Primary Production (NPP)
Gross Primary Production (GPP) vs Net Primary Production (NPP) Even though earth is a closed system for materials and nutrients, it is an open system for the energy. Primary production is the process which inorganic compounds such as water and carbon dioxide are converted into organic compounds through living organisms using an energy source. […]
Difference Between External and Internal Fertilization
The key difference between external and internal fertilization is that the union of male and female gametes in external fertilization occurs outside the female body while the union of male and female gametes in internal fertilization occurs inside the female body. Fertilization is the most important event that takes place in sexual reproduction. In other […]
Difference Between Allele and Trait
Allele vs Trait In 1822, Mendel observed different forms of hybrids by hybridization of pea plants (Pisum sativum) and the statistical relationship between them. The offspring resulted from hybridization showed interesting clear cut differences in the length of stem, color of seed, shape and color of pod, position, and color of seed. These seven […]
Difference Between Virulence and Pathogenicity
The key difference between virulence and pathogenicity is that virulence refers to the degree of pathogenicity of an organism to cause disease while pathogenicity refers to the ability of an organism to cause disease. A pathogen is a microorganism that has the ability to cause disease. Hence, pathogens cause diseases to plants, animals and insects, […]
Difference Between Coelom and Pseudocoelom
Coelom vs Pseudocoelom Coeloms and pseudocoeloms are words to explain the nature of the body cavity in animals. These body cavities are called coeloms. This cavity has surrounded by three cell layers called Ectoderm (outer layer), Endoderm (inner layer) and Mesoderm (middle layer) . These cell layers are formed in embryo through the process […]
