- Carefully observe the cell morphology of the two organisms below. Then, draw the cell morphology. Cells should be drawn large enough so that you can show an accurate shape and arrangement. Your drawing should capture the relative length and width of the cells. There should be no pointy corners, no open circles, no extra “tails” and no overlapping rings. Specify cell morphology and if the organism a) Escherichia coli or b) Staphylococcus aureusarrow_forwardIn 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…arrow_forwardat would happen if an organism lost the ability to carry out cell division?
