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).
1 In plants they are used as energy source and for storage in the form of starch. 2  Cellulose which is a polysaccharide is an important structural component in the cell wall of plants. 3  Sucrose, a disaccharide is a product of photosynthesis and is transported internally.
