Endospores contd Newly formed endospores appear as round, highly refractile cells within the vegetative cell wall, or sporangium Some strains produce autolysins that digest the walls and liberate free endospores The spore protoplast, or core, contains a complete nuclear material, ribosomes, and energy generating components that are enclosed within a modified cytoplasmic membrane.
