Mycoplasmas are bacteria that lack cell walls. On the basis of this structural feature, which statement concerning mycoplasmas should be true?
They are gram-negative.
They are subject to lysis in hypotonic conditions.
They lack a cell membrane as well.
They should contain less cellulose than do bacteria that possess cell walls.
They possess typical prokaryotic flagella.
In the diagram below, identify the structures of a cyanobacterial cell based on the following descriptions:
a) Outer cellular covering which includes:
Mucilaginous layer – outermost layer covering the cell wall; protects the cell from harmful factors of the environment
Cell wall – found just below the mucilaginous layer; 2 or 3-layered, the inner layer lies in between the outer wall layer and plasma membrane; the outer layer is made of peptidoglycan
Innermost plasma membrane – selectively permeable membrane enclosing the cytoplasm
b) Cytoplasm – found below the plasma membrane; the protoplasm which contains structures of different shapes and functions. Lamellae, which contain pigments such as chlorophylls, carotenes, xanthophylls, phycoerythrin and phycocyanin, are located in the peripheral region of cytoplasm. Ribosomes may also be found scattered in the cytoplasm.
c) Nucleic material – the nucleoplasm that is centrally located in the cell and contains chromatin in the form…
