What are living organisms?
Living organisms are made up of cells. Living organisms carry out the vital functions: nutrition,interaction and reproduction. This is what differentiates living organisms from non-living things.

What are cells?
Cells are the smallest living parts
of living organisms. They carry
out the vital functions of nutrition,
interaction and reproduction as
well.
All cells have three parts: a cell
membrane, cytoplasm and genetic
material.
Genetic material controls the
function of the cell.
Cytoplasm is a gel inside the cell.
The cell membrane is a thin,
flexible cover surrounding the
cell. It regulates the exchanges of
substances between the cell and
the exterior.

What are the different
types of cells?
Different types of living organisms
have different types of cells.
There are two main types of cells.
• Prokaryotic cells have the
genetic material within a
certain area of the cytoplasm.
They don’t have a nucleus.
Prokaryotic cells have a rigid
cell wall surrounding the cell
membrane. They often have
flagella to help them move.
• Eukaryotic cells have the
genetic material inside a
nucleus. They have many
different types of organelles.
Organelles perform different
functions, like the organs in the
body. Some of these cells have
a rigid cell wall surrounding
the cell membrane and others
don’t.
