Physiology of excretion is the study of different metabolic activities occur inside our body and gives an idea of which organs and tissues facilitate the excretion mechanism. We sometimes get confused with the terms excretion and egestion. Excretion is a mechanism of eliminating metabolic wastes from the body, while egestion is the process that removes …
Difference between succulents and cacti is mainly due to the following factors like: Presence of areole: Areole is a specialized structure from which spines, flowers, or fruits develops. Its presence is the characteristic feature of all the cactuses, while unusual in succulents. Phenotypic traits: All the cactuses are only having the stem, whereas succulents possess …
Gel filtration chromatography is one of the chromatography methods that facilitate particles separation based on the molecular size. It also called size exclusion and gel permeation chromatography. The source of particle separation is achieved by employing a filtration technique via gel beads. The gel beads possess specific porosity that retains or exclude the components with …
Macrophages can define as the specialized immune cells that primarily recognize the foreign particles, and the cell remainings to facilitate phagocytosis. It differentiates from the monocytes. Besides phagocytosis, macrophages also play a functional role in presenting foreign particles to the T cells and also performs activation of other immune cells by releasing cytokines. Macrophages perform …
Lichens are the complex organisms that show a mutualistic relationship between fungi and algae by possessing characteristics of both. These show polymorphism, as it exists in diversified forms (sometimes plant-like) with different colours, sizes, texture etc. Lichens are not plants, but sometimes these appear as tiny leafless branches or as flat leaf-like structures etc. In …
T cell or T lymphocyte is one of the immune cells that grow in the thymus gland. It performs a significant role in stimulating an immune response. T lymphocytes are different from the other immune cells by having a T-cell receptor on its cell surface. It originates from the stem cells of bone marrow as …
The dark reaction of photosynthesis can define as the phase, which doesn’t need light energy or photons to complete the cycle, and hence also called as “light-independent reactions”. Dark reaction or Calvin cycle was first explained by a scientist named Melvin Calvin. It occurs at the site of the chloroplast within the fluid surrounding the …
The difference between Photosystem I and Photosystem II is primarily due to the following factors: Active reaction centre: P700 is the active reaction centre of PS-I, while P680 is the active reaction centre of PS-II. Photon absorption: PS-I absorbs light of longer wavelengths (ranging between 725-1035 nm), while PS-II absorbs light of shorter wavelengths (<680 …

Difference between cyclic and noncyclic photophosphorylation is mainly due to the following factors: Type of photosynthesis: Cyclic photophosphorylation occurs during anoxygenic photosynthesis while noncyclic photophosphorylation occurs in oxygenic photosynthesis. ATP synthesis: ATP synthesis during the cyclic electron flow of anoxygenic photosynthesis is known as cyclic photophosphorylation. ATP production during the noncyclic electron flow of oxygenic …

Reaction centre can define as the site of photosynthetic reactions. Chlorophyll and pheophytin are the pigments found in a reaction centre. It comprises protein pigments that performs light absorption and excitation of an electron to the higher energy state. Reaction centre is generally seen in photosynthetic organisms like green plants, many bacteria and algae. Photosystem …
