Eukaryotic

What are Eukaryotic Cells?

More complex, with cells larger in side than in prokaryotes, CONTAINING A MEMBRANE-BOUND NUCLEUS.

Cell wall in plant cells are composed of…

Cellulose

Cell wall in fungi is composed of…..

Chitin

THE ________ _________ is pressed tightly against the cell wall. So cannot be distinguished by your microscope.

Plasma Membrane

What are the membrane bound organelles where photosynthesis occurs?

Green Chloroplasts

What microscope do we use in our lab?

Bright Field. To increase contrast, stains or special types of light microscopes with different optical arrangements may be used.

Fluorescence Microscopy

Fluorescent molecules absorb one particular wavelength of light and emit some of that absorbed light at another wavelength. VIEWED ON BLACK BACKGROUND.

Confocal Laser Scanning Microscopy

focuses a laser light source onto a very thin plane. Used to examine specimens that are too thick to be examined with fluorescence microscopy. USED TO CONSTRUCT 3D IMAGES.

Which microscopes have a GREATER RESOLVING POWER?

Electron Microscopy

How does Electron Microscopy work?

Work in a very similar way to light microscopes except the image is produced by a beam of high velocity electrons INSTEAD of a beam of light.

A black and white image of an organism showing a single, circular chromosome concentrated in the central region of the cell.

1. Type of Microscopy:

2. Prokaryotic or Eukaryotic?

3. What is the name of the region containing the chromosome?

1. Transmission electron Microscopy

2. Prokaryotic

3. Nucleoid

A colourful image on a bright background showing thick-walled cells with green organelles.

1. Type of Microscopy?

2. Prokaryotic or Eukaryotic?

3. What might the green organelles be?

1. Bright Field

2. Eukaryotic

3. Chloroplasts

A black and white 3D image of an organism showing its rotating flagellum and thick outer covering.

1. Type of Microscopy

2. Prokaryotic or Eukaryotic

3. What is the name and function of the outer covering

1. Scanning Electron Microscopy
