The key difference between guard cells and subsidiary cells in plants is that guard cells are the specialized parenchyma cells that enclose stomata present in the epidermis of leaves, stems, etc. while subsidiary cells are the surrounding supportive cells of guard cells. Stomata are the pores located in plant epidermis that facilitate the gaseous exchange. […]
Difference Between TGF Alpha and Beta
The key difference between TGF alpha and beta is that TGF alpha is an epidermal growth factor that induces epithelial development while TGF beta is a cytokine-based growth factor that participates in numerous signalling pathways in a cell. TGF alpha and beta are two classes of polypeptide growth factors which take part in many functions […]
Difference Between Metagenomics and Metatranscriptomics
The key difference between metagenomics and metatranscriptomics relies on the type of biomolecules studied in each area. Metagenomics studies DNA, its sequences and its behaviour in organisms, while metatranscriptomics studies the transcribed DNA, mainly mRNA sequences and its behaviour in organisms. Metagenomics and metatranscriptomics are two fields that have gained much popularity over the years […]
Difference Between Cisternal Maturation and Vesicular Transport
The key difference between cisternal maturation and vesicular transport is that in cisternal maturation, new cis cisterna forms, matures, and then, carries secretory cargos forward while, in vesicular transport, secretory cargos move forward across stable and distinct cis, medial and trans-Golgi stack by the vesicles budded off from each cisterna. The Golgi complex is one […]
Difference Between BCAA and Glutamine
The key difference between BCAA and glutamine depends on the requirement of the particular amino acids. Branched Chain Amino Acids (BCAA) are essential amino acids while glutamine is a non-essential amino acid which can be produced in the body. Amino acids are structural monomers of proteins. There are 20 different amino acids in total. Amino […]
Difference Between De Novo and Salvage Pathway
The key difference between de novo and salvage pathway is that de novo synthesis of purine nucleotides refers to the process that utilizes small molecules such as phosphoribose, amino acids, CO2 etc. as raw materials to produce purine nucleotides, while salvage pathway of purine synthesis refers to the process that utilizes purine bases and purine […]
Difference Between Saline and Alkaline Soils
The key difference between saline and alkaline soils is that saline soils have a pH less than 8.5 and an exchangeable sodium percentage less than 15, while alkaline soils have a pH greater than 8.5 and an exchangeable sodium percentage higher than 15. Soil pH is an important parameter in terms of soil fertility. It […]
Difference Between Primary Xylem and Secondary Xylem
The key difference between primary xylem and secondary xylem is that the procambium forms the primary xylem during the primary growth, while the vascular cambium forms the secondary xylem during the secondary growth. Xylem and phloem are the main types of complex tissues in plants. The xylem tissue in higher vascular plants transport water and […]
Difference Between Shoot and Stem
The key difference between shoot and stem is that shoot is an above-ground part of a plant and consists of leaves, buds, flowering stems, flowering buds and the main stem, while stem is the main structural axis of the plant that consists of nodes and internodes. A plant has different parts. Shoot system and root […]
Difference Between Root Hair and Stem Hair
The key difference between root hair and stem hair is that the root hair is a unicellular structure developed as an outgrowth of the epidermis, while the stem hair is a multicellular structure that is not an outgrowth of the epidermis. Root and stem are two main parts of a plant. Stem exists above the […]
