LIVING THINGS                                                                        NON-LIVING THINGS                                                       

1.HUMANS                                                                     1. NATURAL NON-LIVING THINGS             

2.PLANTS                                                                            (moon, starts, rocks,the sun ...)

3.ANIMALS                                                                    2.  MAN-MADE

4. MICROORGANISMS                                                      (buildings, houses, cars, toys, objetcs..)

They are born                                                                        They aren´t born

They grow                                                                             They don´t grow

They perform the THREE VITAL FUNCTION                         They don´t perform the three vital functions

(interaction, nutrition, reproduction)

They die                                                                                They don´t die

They are made of microscopic structures called CELLS      They are not made of CELLS

WHAT IS A CELL? a cell is the smallest living unit that makes up a living thing or an organism. All living things are made up of cells:

1.If the living things is made of only one cell is called UNICELLULAR ORGANISM

Examples: bacteria, algae..

2.If the living things is made of many  cells is called MULTICELLULAR ORGANISM

Examples: human beings, animals and plants.

PLANT CELL

           Basic information                    More information  

ANIMAL CELL

         Basic information                                            More information

  

DIFFERENCES: PLANT AND ANIMAL CELL      

PLANT CELL                                                      ANIMAL CELL                         

It has got a wall                                                   It hasn´t got a wall. It has got membrane

It has got a chloroplast

Chloroplasts contain chlorophylls. 

Chrolophylls make plants green and

it is needed for the photosynthesis.

Large vacuoles contain water                                Small vacuoles contain water 

SIMILARITIES: PLANT AND ANIMAL CELL      

PLANT AND ANIMAL CELL

They have a membrane that controls substances entering and leaving the cell.

The nucleus controls cell functions.
