All processes occurring within organisms, whether single-celled or multicellular, expend energy. The method of procuring that energy, however, differs between organisms. Organisms called autotrophs make their own energy while heterotrophs must feed to obtain their energy needs. Autotrophs such as plan...
Nor do we include mycoheterotrophic angiosperm spe- cies, such as those in the Ericaceae [60], which derive part of their nutrition through a relationship with fungi, be- cause the line between fully parasitic mycoheterotrophs and plants that have mycorrhizal partners is not always clear [61,...
potentially due to their much faster rate of generation turnover [39], which may help them get ahead in the arms race [40]. But in this study, we have not compared the rate of molecular evolution of parasites to their hosts, but of parasites to their free-living relatives. Synonymous su...
They are the only life forms that can produce their own food using energy from sunlight. Plants have green pigment called chlorophyll in their cells, mainly in the leaves. This pigment allows plants to make food from sunlight, water and carbon dioxide in a process called photosynthesis. Plants...
