Question
Chapter 11, Problem 3CT
Summary Introduction
To answer:
Why some species of the gram-positive bacteria lack axial filaments.
Introduction:
The axial filaments are whip-like structures that are present in the central filament of the flagellum. The axial filaments are situated in between the spaces of cell membrane and the external membrane of a bacterium (gram-negative); for example, Spirochetes.

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_forwardWhat prevents Elodea cells from becoming shriveled up like a blood cell would become if placed in a hypertonic solution?arrow_forward
