Last lessons Objective

Gram staining Yogurt lab

1.   Mapping Metabolism

2.   Bacteria Reproduction

3.   Experimental design

Number One

Chemical reactions can:

·      Make things or synthesis or anabolic

·      Break things or decomposition or catabolic

·      Convert acids and bases into water and salt

·      Make energy to store

·      Convert on for of energy into another

·      Make heat

·      Release heat

Day in the life of a bacteria

·      You need to make or get energy

·      You need to digest large molecules into smaller ones

·      You need to absorb nutrients and get ride of waste.

·      You need to make genetic material for cell division

·      You need to construct cell membranes and sometimes cell walls

In class mapping of key activities of life and monera terminology

Examples:

·      Sources of energy : Auto and Heterotroph

·      Means to get energy: Flagella and cilia, saprophytic, parasitic, symbiotic.

·      What happens to the energy

·      Anaerobic and aerobic respiration

·      The topic of waste: endo and exotoxin

·      Cell Division: Binary fission and Conjugation

·      Locomotion and Response to stimuli

Cartoon assignment

Using your metabolism map made in class, create a comic strip entitled “ a day in the life of a bacteria”

Number Two

Asexual makes an exact copy: Binnary Fission

Sexual allows for change in genetic information: Conjugation

Consider the following

1.   Which process allows quick growth?

2.   Which process allows bacteria to adapt to quick change in environment?

3.   Which process could produce resistance to antibiotics?

4.   Which process creates diversity?
