- Cells ( pages 6-7)
All living
things are made up of cells.
Cells are
the basic unit of life.
Cells are
living things with the life processes : interaction, nutrition and
reproduction.
Unicellular organism : one only cell (bacteria)
Multicellular organism: many cells ( trees)

PLANT CELL

Nucleus :
Controls everything
that happen inside the cell.
Cytoplasm :
It is a clear
liquid ( salt and water) . Contains
all the organelles.
Membrane: surrounds and protect the cell

MULTICELLULAR ORGANISM
Cells work
together to carry out a variety of functions.
From the
smallest to the largest:
CELLS:
|
TISSUE:
Cell+cell+cell+… = Tissue
Each type of tissue
has a specific function.
For example , the muscle tissue.
|
ORGANS:
Tissue+tissue+tissue+…
= Organ
Example : the heart
|
SYSTEMS:
Organ+organ+organ+…
= System
Example: the circulatory
system
The basic life
processes are carry out by different systems.
|
ORGANISM:
System+system+system
+ … = organism
