Myxomycetes are
(a) saprobes or parasites, having mycelia, asexual reproduction by fragmentation.
(b) slimy mass of multinucleate protoplasm, having pseudopodia like structures for engulfing food, reproduction through fragmentation or zoospores.
(c) prokaryotic organisms, cellular or acellular, saprobes or autotrophic, reproduce by binary fission.
(d) eukaryotic, single-celled or filamentous, saprobes or autotrophic, asexual reproduction by division of haploid individuals, sexual reproduction by fusion of two cells or their nuclei.
(b) slimy mass of multinucleate protoplasm, having pseudopodia like structures for engulfing food, reproduction through fragmentation or zoospores.
Explanation:
Myxomycetes are acellular plasmodial slime molds i.e. a group of 4 fungus which reproduces through fragmentation or zoospore.
