Monera, Protoctista, and Fungi

UNIT 2

The Monera Kingdom

The Monera Kingdom

contains mostly ________

bacteria

● unicellular● haven't got a nucleus ● found on land, in water, air and

inside other living organisms

● you need a microscope to see them

● they reproduce very quickly

bacteria and humans● bacteria are small,

powerful, and can survive extreme conditions

● bacteria are infectious agentso reproduce quicklyo spread diseaseso can contaminate

food● some bacteria is good!

o like bacteria in our stomach

???????● bacteria are unicellular or

multicellular● bacteria are prokaryotic or

eukaryotic

● bacteria can be found in...

a. airb. waterc. other living organismsd. all of the above

● True or False? Bacteria can be seen by the naked eye? False, you need a microscope!

● three characteristics of bacteria?

● True or False? bacteria are infectious agents.

● Are all forms of bacteria bad for us? Explain.

Small, Simple, Powerful, adaptable etc...

True!

No! Some bacteria is good for us. We need bacteria in our stomachs to digest food and to use as antibiotics to cure us from diseases. Other bacteria purifies water.

The Protoctista Kingdom

● contains unicellular and multicellular organisms

● they live in water or humid earth or other organisms

● examples: o protozoa o algae

protozoa

● Unicellular

● Heterotrophic

● have a nucleus

● very diverse, can be many different shapes

● can cause serious diseases like malaria

● they are useful

● they are used to eat harmful bacteria found in our sewage plants

Algae● put oxygen into the air

● Is used in medicines

● can be eaten and used in food production

● Found in water and sometimes rocks and trees

● UNICELLULAR ALGAEo found in lakes and riverso has a flagella to move around

● MULTICELLULAR ALGAE o seaweed and kelpo form in forests and oceans to provide

shelters

Algae can sometimes reproduce too much

??????????● Where can you find

organisms from the protoctista kingdom?a. waterb. rocksc. both A and Bd. airplanes

● Protozoa are unicellular or multicellular BOTH!

● Is algae autotrophic or heterotrophic

● Where can unicellular algae be found?

and multicellular?

● Four benefits of algae?

Lakes and rivers

Forests and oceans

1. Provide oxygen2. Used in medicine3. Used in food production4. Animals and humans can eat certain

types

The Fungi Kingdom

● Heterotrophic● Feeds on other

organisms● Unicellular (yeast)

and Multicellular (mold and mushrooms)

Yeast ● found in some decaying fruit

and the mouths and skin of some animals

● used to make bread and alcoholic drinks

Mold● Grows on damp floors and

walls● Also grows of fruit and bread● Used to make medicines● Can be dangerous

Mushrooms● Grow in damp, shady places● Decomposers● Some are poisonous● Some are parasitic

Lichens and VirusesLichens

● both fungi and algae● Heterotrophic● Can live on rocks, wood,

soil, leaves…

Viruses● Somewhere between

living and non-living● Can only be seen using a

microscope● They invade, multiply,

and destroy healthy cells

??????????● Three ways fungi are

beneficial

● Which of the following are unicellular?

● Where do lichens grow?

1. Used to make medicine2. Mushrooms decompose 3. Yeast is used to make

bread

A. YeastB. MoldC. Mushrooms

Rocks, wood, soil, leaves...

● Are viruses living or non-living?

● True or False. You need a microscope to see viruses.

● are all mushrooms poisonous?

Somewhere between living and non-living

True.

No, some are poisonous but others we can eat.
