Mc 123 Part 1

Study of microorganisms that includes unicellular, multicellular, or acellular

Study of parasites and their hosts and their relationships with each other

Organisms change over time as a result of changes in heritable physical or behavioral traits

Who is the man behind the theory of evolution?

Is the production of new living organisms or organelles

Is the natural process by which life has arisen from non living matter, such as simple organic compounds

States that many diseases are caused by the presence and actions of specific microorganism within the body.

Name 7 microbes

Includes bacteria and archaea.

They are unicelular

Unicellular

Prokaryotic (no distinct nucleus)

Cell walls composed of carbohydrates and protein complex called peptidoglycan

spherical/ovoid

Rodlike

Corkscrew/ curve

Spirals which are helical and flexicle

-Have cell walls composed of a substance called chitin

-unicellular/multicellular

Mold form visible masses called

mold mycelia

Organisms with nucleus containing DNA surrounded by special envelope nuclear membrane

Unicellular; get nutrients from living house move by pseudopods, flagella or cilia

unicellular; produce oxygen and carbohydrate;

can do photosynthesis

Acellular;

Contain one type of nucleic acid DNA or RNA

Any of the many thallophytic plantlike organisms that consists of a symbiotic association of algae or cyanobacteria and fungu

He discovered the cell ;

Marked the beginning of cell theory that all living things have cells

(1673-1723) First to observe live microorganism using magnifying lens "animalcules" saw it through his single lens microscope

1668

-3 open jars w/ meat (has maggots)

-3 closed jars w/ meat (no maggots)

-3 open jars w/ gauze (no maggots even air can enter )

1745

-He found that after heating nutrient fluids before pouring into covered flask, the cooled solution soon had microorganisms.

-He claimed that microbes developed spontaneously from the fluids.

1765

-Suggested that germs from the air probably entered Needham's solution after they were boiled.

-showed that nutrient fluids heated after being sealed in a flask did not develop judicial growth

-Showed the impotence of 0 to life

-criticized that there was not enough oxygen in the sealed flasks

He said that microbes are present in the air and can contaminate sterile solution but air itself does not create germs

Used phenol (carbolic acid) to kill bacteria in surgical wounds

Established a sequence of experimental steps for directly relating a specific microbe to a specific disease known as koch's postulate

He fired the 1st shot of chemotherapy revolution Salvarsam drug for syphilis

He discovered penicillin from fungus

-To magnify diff types of soil

-used by palmist, skin specialist, to see details of stamp

Magnify up to 1000;

Very short focal length and eyepiece with longer focal length

-Dna is not enclosed within a membrane

-Has one circular chromosomes

-DNA is not associated with histones

-Lack membrane enclosed organelles

-Cell walls contain polysaccharide peptidoglycan

-binary fission

-DNA is found in the cells nucleus-Has multiple chromosomes-sssociated with histones-have a number of membrane enclosed organelles-Cell walls are present-divided by mitosis

If the substance is unorganized and only loosely attached to the cell wall

Which flagella arrangement that is distributed over the entire cell

Divides in 3 planes and remain attached in cube like groups of 8

Those that divide in multiple places and form growls clusters or broad sheets

Bacterias that look like curved rods

A protein found in the hair like appendages and hard for attachment of some gram negative bacteria.

Can occur at the poles of the bacteria cell or they can be evenly distribute over the entire surface if the cell.

Usually longer than fimbriae and only one or or 2 every cell joins bacterial cell in preparation for the transfer of DNA from one cell to another

Prevent bacterial cell from rupturing

Maintains shape of bacteria

A type of passive proces wherein the net movement of molecules is from high to low concentration

Site of protein synthesis, site of some antibiotic action

The process in which pseudopods are used to engulf particles and bring them into the cell and used by WBC to destroy bacteria substances

Fluid portion of cytoplasm

Threadlike mass that appears when the DNA and its associated proteins are not reproducing.

Part of the microscope where a steady light source is used in place of a mirror

Part of the microscope that is the platform where you place your slides. Stage clips hold the slides in place.
