Detailed explanation-1: -So, the correct answer is ‘False’.
Detailed explanation-2: -The cell wall is normally found in the prokaryotes like in bacteria and in cyanobacteria, plant cells, and fungi. The cell wall is absent in the animal cells. Mucor is a fungus. Hence, its cells are surrounded by cell walls.
Detailed explanation-3: -Not all cells have nuclei. In some cells, DNA is present in a tight coil but not enclosed in a nucleus. These sorts of primitive cells called ‘prokaryotes’ (“before the nucleus”) include bacteria. Nucleus is only present in eukaryotic cells (eukaryotes = “true nucleus”) and there is only one of this in each cell.
Detailed explanation-4: -All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
