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?
What are the four criteria for life?
1. All life forms contain DNA.
2. All life forms have a method by which they extract energy from the surroundings and convert it into energy that sustains them.
3. All life forms can sense changes in their surroundings and respond to those changes.
4. All life forms reproduce.
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?
Organisms that are too small to see with the naked eye
What is microscopic?
Exponential Growth
What is population growth that is unhindered because of the abundance of resources?
The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter to sustain the organism’s life functions
What is metabolism?
Flagellum
What is responsible for locomotion?
An organism that feeds on a living host.
What is a Parasite?
A bacteria is autotrophic. How does it get food?
Photosynthesis or Chemosynthesis
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 process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
What is photosynthesis?
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 fimbria?
The sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and structures necessary for life.
What is anabolism?
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?
Special structures that allow living organisms to sense the conditions of their internal or external environment.
What are Receptors?
