  3. Calvin cycle - Wikipedia

    So, 5 out of 6 carbons from the 2 G3P molecules are used for this purpose. Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin ...

    It is a method in which a bud from the plant is joined onto the stem of another plant. [2] The plant in which the bud is implanted in eventually develops into a replica of the parent plant. The new plant can either divert its ways into forming an independent plant; however, in numerous cases it may remain attached and form various accumulations.

    In 1874, Eduard Strasburger discovered the alternation between diploid and haploid nuclear phases, [11] also called cytological alternation of nuclear phases. [15] Although most often coinciding, morphological alternation and nuclear phases alternation are sometimes independent of one another, e.g., in many red algae , the same nuclear phase ...

  9. Plant development - Wikipedia

    en.wikipedia.org/wiki/Plant_development

    Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems [1] located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues.
