Question

What is the difference between amphithecium and endothecium

Answer 1

endothecium: The layer of cells immediately around the endothecium becomes the spore-sac, and an air-space forms between this and the wall of the capsule.The cells of the endothecium divide to form columella. The cells of the columella are arranged in a square in the transverse section.
AMPHITHECIUM: "Amphithecium are the layers of a developing sporophyte of a bryophyte taht give rise to the capsule wall." endothecium: The layer of cells immediately around the endothecium becomes the spore-sac, and an air-space forms between this and the wall of the capsule.
