What enzyme adds base pairs in order to create the new strands in DNA replication?
In plants, sucrose is the major transport form for photoassimilated carbon and is both a source of carbon skeletons and energy for plant organs unable to perform photosynthesis (sink organs).As a molecule translocated over distance, sucrose has to pass through a number of membranes.n plants, sucrose is the major transport form for photoassimilated carbon and is both a source of carbon skeletons and energy for plant organs unable to perform photosynthesis (sink organs).
Totipotent cells serve the same role in plants that stem cells do in animals. They are found in shoot and root growing tips as meristems, and in the cambium layer (the layer of cells between the bark and the wood) of woody plants and trees.
