differentiate leptome and hedrome
Answers
Explanation:
These are tissue types in mosses that are analogous to vascular tissue in vascular plants.
proposed definition of hydrome (PO:0030047): A portion of plant tissue that has as parts hyrdoids.
Comment: Found in bryophytes, in the center of a non-vascular shoot axis such as a gametophore axis or seta, or in the midrib of a non-vascular leaf. Often surrounded by leptome. May function in conduction of water and minerals and in support, similar to xylem in vascular plants.

Synonyms: hydrom, leptoxylem (Hebant)
proposed definition of leptome (PO:0030048): A portion of plant tissue that has as parts leptoids.
Comment: Found in bryophytes, in non-vascular shoot axes such as a gametophore axis or seta, or in the midrib of a non-vascular leaf. Often surrounding a central hydrome. May function in the conduction of organic substances, similar to phloem in vascular plants.

Synonyms: leptom, leptophloem (Hebant)
leptome:- in particle physics, a lepton is an elementary particle of half-integer spin (spin 1 ⁄ 2) that does not undergo strong interactions. Two main classes of leptons exist: charged leptons (also known as the electron -like leptons), and neutral leptons (better known as neutrinos.
hedrome:- in nouns denoting geometric solids having a specified number of plane faces.
