The difference between vascular and nonvascular plants is mainly characterized based on the presence or absence of vascular tissues and their categorization in the plant taxonomy. The presence or absence of vascular tissue distinguishes the vascular plants containing lignified vascular tissues from the nonvascular plants that lack a specialized vascular system. The translocation of food, …

The life cycle of bryophytes has two alternations of generations, one is haploid gametophyte generation, and the other is diploid saprophytic generation. In both the life cycle, the bryophytes possess different morphology and physiological functions. The haploid gametophyte phase lasts longer or dominates the diploid saprophytic phase between these two alternations of generations. Heterosporous bryophytes …
Phylum Porifera is placed in the kingdom Animalia and regarded as the oldest animal group. The term Porifera merely refers to pore bearers that include Poriferans or pore bearing animals. Poriferans or sponges possess small pores on their entire body and some wide openings. The members of Phylum Porifera are metazoans that show a cellular …
The difference between the food chain and the food web is mainly due to the network of links and the number of trophic levels the organisms form in the different ecosystems. A food chain is a one-way pathway that includes a linear network of linking organisms. In contrast, a food web shows a complex network …

Gel filtration chromatography is one of the chromatography methods that facilitate particles separation based on molecular size. Size exclusion, molecular sieve and gel permeation chromatography are the alternative names of gel filtration chromatography. The porous gel matrix is the stationary phase that contains a hydrated, sponge-like material. Oppositely, the buffer solution or aqueous phase functions …
Macrophages differentiate from monocytes. They are specialized immune cells that primarily recognize the foreign particles and cell remains through toll-like receptors. Then, they phagocytose foreign particles by amoeboid movements through phagocytosis. Macrophages also play a functional role in presenting foreign particles to the T cells and thereby causing the destruction of potential pathogens. They activate …
