    Virus is an obligate intracellular parasite which can reproduce only by invading and taking over other cells as they lack the cellular machinery for self reproduction. Viroids are subviral, smallest known agents of infectious disease. The term viroid was coined by T.O

    Viroids are free RNA molecules of low molecular weight without any protein coat while viruses can have either RNA or DNA molecules encapsulated in a protein coat. Viroids are smaller in size than viruses.

    Spermatophore: The sperms produced from testes, while the cockroach is still young, are brought by the vasa deferentia into the seminal vesicles for storage. The sperms in the seminal vesicles are glued together in the form of bundles called spermatophores.

    The chemiosmotic hypothesis was proposed by Peter Mitchell. This hypothesis stated that a proton-motive force was responsible for driving the synthesis of ATP. In this hypothesis, protons would be pumped across the inner mitochondrial membrane as electrons went through the electron transfer chain. The chemiosmotic hypothesis suggests that the action of ATP synthase is coupled with that of a proton gradient. ... It is the action of the proton gradient that causes a proton motive force that allows ATP synthase to phosphorylate ADP and inorganic phosphate to ATP.

    1. In mitosis the parent cell divides into two daughter cells while in meiosis the parent cell forms four daughter cells. 2.mitosis is the equational division ,i.e. in mitosis chromosome number in daughter cells is same as in parent cell,but meiosis is reductional division ,ie. the chromosome number in daughter cells is half as compared to parent cell.

    Intrinsic factor is a glycoprotein secreted by parietal (humans) or chief (rodents) cells of the gastric mucosa. In humans, it has an important role in the absorption of vitamin B12 (cobalamin) in the intestine, and failure to produce or utilize intrinsic factor results in the condition pernicious anemia.

    Prokaryotic cell envelope possess chemically complex cell envelope. The cell envelope comprises of three layers: the outermost glycocalyx, the cell wall and the plasma membrane. All the three layers together act as a single protective unit. Gram positive:- Cells that take up the gram stain and are stained dark blue or purple. Gram negative:- Cells that do not take up the gram stain and are stained pink or light red. If glycocalyx is present as a loose sheath it is called slime layer. At times glycocalyx is present as thick and tough layer then it is called capsule. The cell wall determines the shape of the cell and also provides structural support to the cell. The plasma membrane is semi-permeable in nature. Bacteria may be motile or non-motile based on the presence of thin filamentous extensions called flagella. Flagella helps in motility. Bacterial flagella are composed of three parts − 1.Filament 2.Hook 3.Basal Body Pili are elongated structures made up of pilin proteins. Fimbriae are small bristle like fibres which mostly help in attachment of the bacteria to different surfaces.
