True or False Cell walls are present in the cells of archaea, bacteria, algae, fungi, and plants only. Photosynthetic unicellular prokaryotes such as Oscillatoria exhibit a green color when viewed under a microscope because of the presence of numerous chloroplasts. The nuclear membrane is a double-membrane structure that constitutes the outermost portion of the nucleus and is continuous with the Endoplasmic Reticulum.
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…
