1. THE STRUCTURE OF LIVING
THINGS

2. CELLS
Our bodies are made from enormous
amounts of tiny components called cells.
There are many different types of cell,
but they all share a basic structure.
● The cell membrane
● Cytoplasm: it contains organelles.
● Nucleus:
-Eukaryotes are cells with a nucleus.
-Procariotes:are cells without nucleus.
● Procariotes:
Eucariotes:

3. MULTICELLULAR BEINGS
Most living things (ferns, insects,
birds and humans) are
multicellulars beings, made from
millions of cells.
These cells organise themselves
into differents levels.
These levels are: tissues (made
from cells),organs (formed by
tissues) and systems (groups of
organs).

4. HUMAN ORGAN SYSTEM
● Humans have the most complex body
organisation and structure of all
multicellular living things.
● Our bodies' organ systems work together
to carry out three live processes: nutrition
intergration and reproduction.
● Unicellular beings have cell that live in
independenty but cells in multicellular
beings need to be together and cooperate
to surving.
