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 […]
Difference Between Bryophytes and Seedless Vascular Plants
The key difference between bryophytes and seedless vascular plants is that bryophytes are non-vascular plants, while seedless vascular plants are vascular plants that do not produce seeds. Kingdom Plantae is the kingdom that consists of all plants on Earth. Plants are multicellular eukaryotes which are photoautotrophic. Based on the plant body, vascular tissues and seed […]
Difference Between Lycopodium and Selaginella
The key difference between Lycopodium and Selaginella is that Lycopodium is a clubmoss which is homosporous (one type of spore) while Selaginella is a spike moss which is heterosporous (two distinct types of spores). Lycophyta is a subgroup of vascular plants belonging to Kingdom Plantae. They are also known as fern-allies. They are primitive plants […]
Difference Between Bipolar Cells and Ganglion Cells
The key difference between bipolar cells and ganglion cells is that bipolar cells are interneurons present in the second layer of the retina which transform visual information from photoreceptors to ganglion cells while ganglion cells are retinal ganglion neurons in the third layer of the retina that carry the nerve impulses from bipolar cells to […]
Difference Between Blood and Hemolymph
The key difference between blood and hemolymph is that blood contains red blood cells, and it transports oxygen while hemolymph does not contain red blood cells and is not involved in oxygen transport. Blood and hemolymph are two different types of circulating fluids found in organisms. Blood is the fluid circulating in vertebrates while hemolymph […]
Difference Between Urodela Anura and Apoda
The key difference between Urodela Anura and Apoda is that amphibians belonging to Urodela have a long tail and two pairs of limbs of about equal size while amphibians belonging to Anura have long hind limbs and are tailless. Meanwhile, the amphibians belonging to Apoda lack limbs. Amphibians are a group of vertebrates. They can live […]
