Presenting... Protists!

A Communication AssignmentBiology 10

What to do:• Create two or three interesting powerpoint slides about a

protist and give a 2-3 minute presentation!• Include:

– A picture of your protist – What kind of a protist it is and what structures it has– Where it lives– What it eats– How it interacts with its environment and it’s impact on

humans– Anything else unusual about it

• Your sources of information

• BONUS – a cool YouTube video showing your protist in action (max length that can be shown in class 30s)

How to earn good marks:Powerpoint slides• All the required information is included• The slides contain key points only• The slides are attractive and easy to read• Pictures and text animations are included

Presentation skills• The presenter spoke loudly and clearly; he or she was

easy to understand• The presenter looked at the audience and did not

read from the slides• The presenter did not go over 3 minutes• The presenter explained the key points and pictures

The RUBRIC:

• Use the rubric to judge the following presentations!

YOU be the JUDGE!

Foraminifera• The Foraminifera, ("hole bearers") or

forams for short, are a large group of amoeboid protists with reticulating pseudopods, fine strands of cytoplasm that branch and merge to form a dynamic net.[1] They typically produce a test, or shell, which can have either one or multiple chambers, some becoming quite elaborate in structure.[2] These shells are made of calcium carbonate (CaCO3) or agglutinated sediment particles. About 275,000 species are recognized, both living and fossil. They are usually less than 1 mm in size, but some are much larger, and the largest recorded specimen reached 19 cm.

Forams• Modern forams are primarily marine, although some can

survive in brackish conditions.[10] They are most commonly benthic, and about 40 morphospecies are planktonic.[1] This count may however represent only a fraction of actual diversity, since many genetically discrepant species may be morphologically indistinguishable.[11]

What score do you give it?

Foraminifera: A type of sarcodina (animal-

like)

• Single celled, 1mm• Secretes a shell – Calcium carbonate

• Psuedopods stick out of holes– Move after their prey!– Eat phytoplankton like dinoflagellates

• Live in the ocean– Benthic and planktonic

Fossil forams

Forams are stars!

• When they grow – they leave their shell behind– Create sand• 1 g of sand = 50,000 foram shells

– Create limestone deposits• Useful for determining how old a

rock is• Seeing changes due to global

warming

Check out a cool foram!
