Phloem cell drawing

WebbPlants create sugar in the mesophyll cells of their leaves by photosynthesis. This sugar, mostly sucrose, has to be loaded via the bundle sheath into the phloem vascular system (the sieve elements), where it is distributed to growing parts of the plant. We analyze the feasibility of a particular loading mechanism, active symplasmic Webb(ii) In the space below, make a large drawing of the three xylem vessels enclosed in the box.
