Hi! I've studied a cross section(40X) of a Nymphaea leaf and were supposed to locate hydrenchyma. I know that hydrenchyma is water storing parenchyma cells, which makes sense since Nymphaea is a water lily of some sort. however, all the anatomical features I was able to identify were spongy and palisade mesophyll, along with some empty space that functions in gas storage and maybe floating. in what part of the leaf is the hydrenchyma located?

Helo! I don´t know if this is relevant for you, but this link takes you to a picus leaf. Picus contains hydrenchyma. I don´t think that Nymphaea contains hydrenchyma. The best part is that the Picus leaf looks like a pizza! See you tomorrow :D

Nymphaea does not have hydrenchyma. Why would a water plant need to store water? No, Nymphaea only needs to store air - the tissues that are under water need oxygen for respiration - reason why you are seeing empty space.
