Bacterium Cell Structure
Helps bacteria adhere to surfaces and is a protective layer to deter infection fighting agents.
What is the capsule?
Pathogen
What is bacteria that are harmful?
The most common way that bacteria obtain food.
What is as decomposers?
Determines whether a chemical can enter a cell
What is the plasma membrane?
Strains
What are organisms from the same species that have markedly different traits?
Maintains the shape of a cell, holds in the contents of the cell and regulates water absorption.
What is the cell wall?
Saprophyte
What is an organism (bacteria) that feeds on dead matter?
Parasitic Bacterium are...
What is heterotrophic?
Exponential Growth
What is population growth that is unhindered because of the abundance of resources?
Methods to reduce the risk of food bacterial contamination.
What is: a) expose food to extreme heat or radiation b)dehydrate it c) freeze d)pasteurization of dairy?
Flagellum
What is responsible for locomotion?
An organism that feeds on a living host.
What is a Parasite?
The six kingdom system replacement for Monera.
What are Archaebacteria and Eubacteria?
The 5 steps of asexual reproduction of bacteria.
What are: a) DNA loop is attached to the plasma membrane, b) DNA is copied and then copy attaches to the plasma membrane close to the other one, c) cell wall elongates separating the two strands of DNA, d) new cell wall and plasma membrane form cutting strands off from each other, e) when cell wall and plasma membrane growth complete then two bacteria exist. Identical if no mutation.
The four Phylum and their characteristics.
What are: a)Gracilicutes - gram negative, b)Firmicutes - gram positive, c)Tenericutes - no cell wall, d)Mendosicutes - have a cell wall but significantly different than gram stain ones.
Cytoplasm
What is a semi fluid substances in the cell supporting the DNA and ribosomes?
Aerobic Organism
What is an organism that requires oxygen to get energy from its food?
Three common bacterial shapes.
What are spherical, rod-shaped (bacillus), helical (spirillum)
Help bacteria to grasp things around it or as a part of reproduction.
What are fimbriae?
Class of Phylum Tenericutes and Mendosicutes
What are Mollicutes and Archaebacteria
Ribosomes
What are chemical factories making proteins?
Logistic Growth
What is population growth that is controlled by limited resources?
Five conditions for ideal bacterial growth.
What are : 1) Moisture 2)Moderate temperature 3)Nutrition 4)Darkness 5)Proper amount of oxygen?
Endospore
What is the DNA and other essential parts of a bacterium coated with several hard layers?
Classes in A. Gracilicutes and B. Firmicutes
What are:
A: Scotobacteria- non photosynthetic bacteria; Anoxyphotobacteria - non oxygen producing photosynthetic bacteria; Oxyphotobacteria - oxygen producing photosynthetic bacteria.
B: Firmibacteria - bacilli or cocci; Thallobacteria - all others
