The key difference between collagen elastin and reticular fibers is that collagen fibers are the most abundant type of fibers in the extracellular matrix of connective tissues while elastin fibers are tiny fibers that can stretch and recoil and they are found in elastic tissues. Meanwhile, reticular fibers are highly branched fibers which form a […]
Difference Between Amacrine and Horizontal Cells
The key difference between amacrine and horizontal cells is that amacrine cells receive information from the bipolar cells while horizontal cells receive information from photoreceptors. Photoreceptors, bipolar cells, ganglion cells, horizontal cells and amacrine cells are the five types of neurons found in our retina. All these neurons contribute to the processing of visual information in […]
Difference Between G1 G2 and S Phase
The key difference between G1 G2 and S phase is the growth that occurs. During the G1 phase, the cell shows first growth by copying organelles and making the molecular building blocks which are necessary for later steps; during the G2 phase, the cell shows second growth by making proteins and organelles and beginning to […]
Difference Between Gametic Sporic and Zygotic Meiosis
The key difference between gametic sporic and zygotic meiosis is that gametic meiosis is the meiosis that occurs during the formation of male and female gametes while sporic meiosis is the meiosis that occurs during the sporogenesis and zygotic meiosis is the meiosis that occurs in the zygote. Most life cycles include both haploid and […]
Difference Between Connective Tissue Proper and Specialized Connective Tissue
The key difference between connective tissue proper and specialized connective tissue is that connective tissue proper consists of loose connective tissue and dense connective tissue while specialized connective tissue consists of reticular connective tissue, adipose tissue, cartilage, bone, and blood. There are four basic types of tissues in the animal body. Connective tissue is one of these types and it is […]
Difference Between Quiescent and Senescent Cells
The key difference between quiescent and senescent cells is that quiescent cells are in the reversible G0 state while senescent cells are in the irreversible G0 state. Generally, a cell cycle has G1, S, G2, mitosis (nuclear division) and cytokinesis. Actively dividing cells undergo all these stages, and it is known as a replicative cell […]
Difference Between Keratinized and Nonkeratinized Epithelium
The key difference between keratinized and nonkeratinized epithelium is that keratinized epithelium is impervious to water while nonkeratinized epithelium is pervious to water. Based on the presence of keratin protein, there are two types of epithelia as keratinized epithelium and nonkeratinized epithelium. Keratinized epithelium forms the epidermis of land vertebrates. Nonkeratinized epithelium lines the buccal […]
Difference Between Catecholamines and Noncatecholamines
The key difference between catecholamines and noncatecholamines is that catecholamines are mainly direct-acting adrenergic drugs that have catechol, while noncatecholamine can be direct-acting, indirect-acting, or dual-acting adrenergic drugs that do not have catechol. Adrenergic drugs mimic the effects of adrenergic nerve stimulation. Catecholamines and noncatecholamines are two types of adrenergic drugs. They can be direct-acting […]
Difference Between Generative Nucleus and Pollen Tube Nucleus
The key difference between generative nucleus and pollen tube nucleus is that generative nucleus is one of the two male nuclei of seed plants that fuses with the female nucleus in the embryo sac while pollen tube nucleus is the nucleus that guides pollen tube to grow along the pistil into the female embryo sac. […]
Difference Between Muscularis Layer of Esophagus and Stomach
The key difference between muscularis layer of esophagus and stomach is that muscularis layer of the esophagus has two layers while muscularis layer of the stomach has three layers. Gastrointestinal tract or GI tract has four layers. They are mucosa, submucosa, muscularis and serosa. Each layer is composed of different tissues. They also fulfill different […]
