Are pulp cells (in oranges) normal plant cells? Does a pulp cell contain all the elements that a 'normal' plant cell contains? I've searched for an hour to find more information about this but couldn't find anything useful. Is the pulp cell the exception from the general size range of most eukaryotic plant cells, normally between _10 - 100 µm_? Please include link to a reputable website. !orange pulp cell

They are not individual cells. In fact, the "juice sacs" (as they are known) are actually specialized, multicellular hairs:

> Juice sacs originate as multicellular hairs in which the interior of the enlarged distal part breaks down and fills with liquid. The juice sacs constitute the fleshy, edible pulp of an orange and are the source of the sweet juice.
