‘the inert/non-living’ from ‘the living’ of which a an organism has to posses in order for it to be considered as a living being. These include self organization or movement‚ growth‚ reproduction‚ inheritance‚ feeding‚ excretion‚ sensitivity and adaptation. Moreover‚ the question of what life is takes us back to evolution‚ that is‚ for an organism to be considered living‚ it has to be part of the fossil record. Even so‚ there are living organisms which do not show some of these characteristics of life

Existing organisms are separated into dual sets on the foundation of their cellular arrangement: prokaryotes and eukaryotes. Approximately 3.5 billion centuries in the past‚ prokaryotic organisms conquered our world. Afterwards‚ around 1.5 billion centuries ago‚ a nucleated cell named eukaryote evolved then the Cambrian blast‚ in the vicinity of 0.5 billion centuries ago‚ aided in the development of multicellular entities. The cell partitions of prokaryotes are normally designed

thing and a rock isn’t Cells All living things and organisms have cells. Cell is a collection of living matter. Any living thing that is made up of a single cell is a unicellular organism. The organism that is most familiar is a multicellular organism for example animals and plants. A rock unlike a plant or an animal does not any cells that can grow‚ reproduce‚ or respond to the environment. Reproduction All organisms can make new organisms through a process called reproduction. There are two

genetic material’s ability to multiply into double-stranded genetic material‚ and how the double-stranded material (DNA) still has some resemblance to the one-stranded genetic material. DNA base composition is a genetic method used to compare related organisms through their genetic material (DNA). This new more scientifically sound evidence has enabled new findings such as Achaea’s newfound relation to Eukaryotes. Physically‚ Archaea seemed to be more closely related to bacteria‚ but genetically Archaea

Premium DNA Metabolism Protein
Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

(methods used to get rid of wastes) Amoeba possess a contractile vacuole for excretion and osmoregulation . Undigested food is excreted by exocytosis . Some wastes wastes‚ and CO2 are excreted through the plasma membrane by diffusion feed on micro-organisms like bacteria‚ algae‚ and yeasts. In order to gather its food the paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove They Exrect water from the contractile vacuole or they will

THE SEARCH FOR BETTER HEALTH 1.What is a healthy organism? Discuss the difficulties in defining the terms ‘health’ and ‘disease’ * Health – state of physical‚ mental and social wellbeing. It is not just absence of disease * disease – any condition which effects the functioning of any part of a living organism * difficulties in defining health and disease; * health 1) the definition of health varies with age eg stiffness in the joints is probably more common in a 90yo
