1º de ESO: The simplest living things 6

  

  

       

1.- WHAT IS THE PROTOCTISTA KINGDOM?

The Protoctista kingdom includes unicellular and multicellular living

things. They are all eukaryotes and have no tissues. Protozoa and algae are

found in this kingdom.

Ciliate protozoa

Listen to the following text and fill in the blanks:

1.1.- What are protozoa?

The main characteristics of protozoa are:

• ________________.

• ______________. They feed on bacteria, organic remains and other

microscopic organisms.

• They live in salt water and ______ water.

• Some are __________, and cause illnesses.

Vorticella

1º de ESO: The simplest living things 7

  

  

1.2.- How many groups are there?

There are four groups of protozoa. They are classified according to the way

they move:

• Flagellates: They move using a flagellum or tail. Trypanosoma

causes sleeping sickness.

Trypanosoma between blood cells

• Ciliates: They move using cilia. Paramencium is shaped like a

slipper, it has two nuclei.

Paramecium

• Rhizopods: They use pseudopods, projections of cell cytoplasm.

Entamoeba histolytica causes dystentery.

Entamoeba histolytica

1º de ESO: The simplest living things 8

  

  

• Sporozoa: No movement. Plasmodium causes malaria.

Plasmodium

1.3.- What are algae?

The main characteristics of algae are:

• Unicellular or multicellular. Unicellular algae sometimes form

colonies. Each cell can carry out the vital functions. Therefore, algae

have no true tissues or organs.

 

Volvox unicellular algae

Unicellular algae

1º de ESO: The simplest living things 9

  

  

• Autotrophs. They contain chlorophyll and other pigments which

capture sunlight for photosynthesis. They can be classified by their

pigment: green, brown or red.

• Some live in salt and fresh water, but others live on tree trunks or

rocks. Some unicellular algae, like diatomea, float on water forming

phytoplankton, and are food for aquatic animals.

• Algae provide food for humans too, for example, ice cream is

made from algae. Industrial uses include medicines and fertilizers.

Algae pasty

1º de ESO: The simplest living things 10

  

  

1.4.- How many groups are there?

• Green algae. They are mainly green and live on the surface of salt

water or fresh water. For example: Euglena, Ulva.

Green algae

• Brown algae: They are green and yellowish pigment. They live in

salt water, on rocky coasts and on the surface of water. For example:

Diatomeas, Sargazos.

Brown algae

• Red algae: They are green and red in colour, and they live in warm,

still ocean water. For example: Coraline.

Crossword:

Can you spell …..?

Can you help me with the word in ….?

I think the first letter is ….?

What do you think ……. is?

 

More activities:

1.- Describe how each group of protozoa move. Example:

… move using …, …do not move.

2.- What do algae have in common with plants?

3.- Compare protozoa and algae?

…live in… .

… are autotrophs, but … are … .

1º de ESO: The simplest living things 13

2.- WHAT IS THE MONERA KINGDOM?

a.- First, let’s see the next video about bacteria:

b.- And now, listen to the following text and fill in the blanks:

This kingdom contains unicellular, ________, prokaryotic organisms. They

do not have an organized ___________.

Bacteria belong to the _______ kingdom. They can live almost anywhere.

They sometimes form _________, but each individual cell remains

independent. The first living things on _______, more than 3,500 million

years ago, were probably _________.

2.1.- Bacteria nutrition

Most bacteria are heterotrophs: they do not produce their own food.

Parasites feed off of living things. They cause illnesses like

tuberculosis and cholera.

1º de ESO: The simplest living things 14

  

  

• Saprophytes live on dead or decomposing matter. They transform

organic substances into inorganic substances. Lactobacilo is used to

make yoghurt.

• Symbionts live on the bodies of other living things to provide

mutual benefit. They can be found in the digestive system of many

mammals, where bacteria help with digestion.

• Some bacteria are autotrophs. For example, cyanobacteria make

their own food through photosynthesis.

2.2.- Bacteria reproduction

They reproduce by binary fission, producing two daughter cells. Each

daughter cell grows and then divides again.

1º de ESO: The simplest living things 15

  

  

2.3.- How many groups are there?

Bacteria can be classified into four groups by their shape:

• Coccus. Spherical

• Bacillus. Rod-shaped

• Vibrio. Curved-rod shaped

• Spirillum. Helical

A.- Find words in the text which mean the following. 1. infant: 2. separated: 3. contagion: 4. changes: 5. occupy: 6. attach:

B.- Correct the information in each sentence.

1. The bacterium E. coli is in the intestine before birth. 2. E. coli never causes diarrhea among infants. 3. .E. coli is just a commensal organism of the large intestine. 4. An E. coli strain, once established, may persist only for a few days.

C.- Think and answer.

1. Who did describe first E. coli? 2. Where did he find it? 3. Can E. coli cause diarrhea in humans? 4. How does E. coli reach the human large intestine? 5. How much time does a E. coli strain persist in our large intestine?

         3.- Find the words in the list on the right:

Did you find …………….?

Can you show me where ………?

2.- Draw a bacteria cell and label it: cell wall, cell membrane,

cytoplasm.

…do not move.

6.- What do algae have in common with plants?

7.- Compare protozoa and algae.  

     

1º de ESO: The simplest living things 19

3.- WHAT ARE VIRUSES?

Viruses are not cells, so they are not really living things. They cannot carry

out any vital functions by themselves. They infect living cells and then can

reproduce. They are always obligate parasites: as a result they cannot live

independently of their host.

3.1.- What is a virus like?

The main characteristics of viruses are:

Extremely small. They can only be seen through an electron microscope.

Unable to move.

Extensive habitat. They are found on the ground, in the air and in the

water.

Parts of a virus

1º de ESO: The simplest living things 20

3.2.- Virus infection process

1.- The virus enters the cell.

2.- Reproduction: viruses use the infected cell for making the viral

components.

3.- Assembly of viral components.

4.- New viruses leave the cell.

1º de ESO: The simplest living things 21

Project: Let’s discuss about viruses

Listen to the following information and try to fill in the blanks with the

words below:

Infectious agent, plants, non-bacterial, ecosystem, virology, virions, DNA,

protein coat, shapes, hundredth, light microscope.

1.- What is a virus?

2.- In groups, discuss with your partner: are viruses living beings?

In my opinion ….

I think that ….

I don´t agree with you because…

After a few minutes we can share our ideas with the rest of the class.

3.- Finally, the same groups can investigate about a few famous viruses,

each group will choose a different one, like: HIV, Influenza, Varicella, etc..

After that, they will make a presentation with their computer with all the

information and photos they have been searching for and present it to the

rest of the class.
