How to Create 3D Plant Cell and Animal Cell Models for Science Class

Characteristics of living things.

       Characteristics of living things:

NUTRITION 
RESPIRATION
EXCRETION
REPRODUCTION
GROWTH
MOVEMENT
INTERACTION 

• NUTRITION

Living things take in food to obtain energy. 

• RESPIRATION

Living things exchanges gases with the environment.

• EXCRETION

Living things get rid of the wastes they produce. 

• REPRODUCTION

Living things produce new lives.

• GROWTH

Living things grow and change.

• MOVEMENT

Living things o certain parts of them can move. 

• INTERACTION

Living things react to the changes in the environment.  






Nutrition
Living things take in food to obtain energy.

 

Respiration
Living things exchange gases with the envoronment.  






Excretion
Living things get rid of the wastes they produce. 



Reproduction
Living things produce new lives. 


Growth
Living things grow and change. 


Movement
Living things or certain parts of them can move. 


Interaction
Living things react to the changes in the environment. 

2. Five living things  and five non-living things. 
   

What differences can you find between the two charts?

  -Living things are born,              -Non-living things don't need
  they grow,                                    air and food like me and you.
  they reproduce and                      They can be:
  they die.                                            -natural or
  They need oxygen, food                   -man-made.
  and water to live.  

 3. Name the life forms in each photo. 
     Do you know which kingdom they belong to?

  









  



LIFE FORMS: jellyfish, toadstool and bacteria. 

KINGDOMS THEY BELONG TO:
       -A jellyfish is an invertebrate animal. 
       -The toadstool is a fungus. 
       -Bacteria belong to a kingdom called Monera. 


4. Look at the words below. 
    Do you think these things are living or non-living?

    mould =moho....................living thing.
    seed=semilla......................seed is a dormant living.
    water=agua........................non-living.
    mineral=mineral................mineral.
    moss=musgo......................living.
    spider=araña.......................living.

              a. Fungi can't make their own food.

    











   b. Algae belong to the Protist Kingdom.

       c. Animals are multicellular.

      








 d. Yeasts are unicellular fungi. 

     







 e. Algae can make their own food.


 

       



f. Viruses aren't considered living things.

 

a. Chloroplasts. They contain chlorophyll and

                           only plant cells have them. 

 

b. Cell membrane.  It controls what enters and

                                leaves the cell.

c. Nucleus. It controls all the functions of the cell.

d. Cytoplasm. Most chemical reactions take place

                        here.

e. Cell wall.  They give cell plants their shapes.

a. The small units that make up living ghings are
     called  CELLS. 

b. MICROSCOPES are scientific instruments 
    that allow us to see cells.

c. The organisms made up of many cells are called
    MULTICELLULAR organisms. 

d. DICHOTOMOUS keys are used to identify and
    classify organisms. 

How are living things classified?

HOW ARE LIVING THINGS CLASSIFIED?

 LIVING THINGS ARE CLASSIFIED

INTO FIVE GROUPS CALLED KINGDOMS.

They have been grouped this way 

                  because

organisms of the same kingdom:

-----share similarities and 

-----are different from organisms in other kingdoms. 

 

PLANT KINGDOM 

    a. Plants are multicellular. 

    b. They make their own food through a process called

         photosynthesis.

    c. Examples: trees, cactus, 

PROTIST KINGDOM  

    a. Protists are usually unicellular, but some are multicellular. 

    b. Most protists are found in water. 

    c. Examples: amoeba (unicellular)

                          algae (algae can be unicellular or multicellular)

   

Are algae plants? 

What kingdom do they belong to?

 kelp

MONERA KINGDOM

     a. All organisms are unicellular. 

     b. They can be found on land, in the air, in water and 

                              inside other living things. 

     c. Example: bacteria. 

ANIMAL KINGDOM

     a. Animals are multicellular. 

     b. They get the energy they need  by feeding on other living 

          things. 

     c. Examples: lion, octopus, spider, fish, bird....

FUNGUS KINGDOM 

     a. Fungus can be unicellular or multicellular. 

     b. They obtain the nutrients they need from the remain of 

          dead plants and animals.

     c. Examples: Yeasts are unicellular fungi. 

                           Mushrooms are multicellular fungi. 

VIRUSES ARE MICROSCOPIC 

AND CAN CAUSE DISEASE. 

Most scientist don't consider viruses living things

because they don't take in nutrients, 

              they produce no waste products, 

              they don't grow, and

              they don't respond to stimuli. 

In order to reproduce they must always be 

inside another living thing.
