Several Archaea and Bacteria possess the ability to travel by swimming. This motility is aided by the presence of thin structures referred to as flagella (in Bacteria ) or archaella (in Archaea ). Prokaryotic cells can be subjected to appropriate staining techniques and the flagella can be visualized using a light or electron microscope. Flagella are attached on the surface of the cell in several different locations. Based on the distribution of flagella, the flagellar arrangement is categorized as monotrichous, amphitrichous, lophotrichous, and pertrichous.

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…

1a) Which protein of the flagella is located in the cytoplasmic/cell membrane? b) What organelle is defined as a house of energy for the cell? c) Which part of phospholipid layer is hydrophobic in cell membrane? d) Name where flagella can be found? e) Which organelle shares its membrane with the nucleus membrane?

The Amoeba, the paramecium, and the euglena ( These are unicellular Protozoans) produce electrical impulses that travel along their cell membrane. This is possible because they are specialized to use properties exhibited by all cells. These properties include ... A) Separation of the fluid environments inside and outside the cell B) Active transport of Na+ out of and K+ into the cell. C) Portal proteins that allow diffusion of Na+ and K+ back in to the cell D) Maintaining unequal Na+ and K+ concentrations on the two sides of the membrane. E) All of these are true Explain why
