Harvesting

1. (Science: cell culture) The collecting of cells, organisms, or the growth medium upon which an experimental population (of cells or microorganisms) had grown, so that the collection can be analysed or so biochemicals can be extracted from it.

2. (Science: zoology) harvesting ant, any species of ant which gathers and stores up seeds for food. Many species are known.

The species found in southern Europe and Palestine are Aphenogaster structor and a. Barbara; that of Texas, called agricultural ant, is pogonomyrmex barbatus or Myrmica molifaciens; that of Florida is pogonomyrmex crudelis.

Re: Do all cells have the ability to perform photosynthesis?

... some algae, some plankton (not sure where they are classified), and a very few archaebacteria (I think) can do photosynthesis. We lack the light harvesting centers and the enzymes like Rubisco that fix carbon dioxide.

photosynthesis

... probably simplified to an extreme (especially the calvin cycle as no enzymes are mentioned.) As visible spectra comes into contact with the light harvesting units of the chloroplast’s thylakoid membrane (PSI, PSII,) quantum’s of energy are absorbed and electrons on ground state are thus excited. ...
