LIVING
BEINGS
Living
beings are made of cells and theycarryout three vital functions.
The
cells are
microscopic units all living beings are made of.
They
have 3 parts:
-
Membrane (it protects the cell)
-
Cytoplasm (a thick liquid inside the membrane)
-
Genetic material (controls the cell’s activity)
Most living things have
eukariotic cells
(their genetic material isinside the nucleus).
Bacteria have prokaryotic
cells with no
nucleus.
Cells and organization
Unicellular organisms are
made up of one cell (bacteria, potozoa…).
Multicellular organisms are
made up of lots of cells (plants, animals…)
Some multicellular organisms
(humans) havegroups of cells organised into:
-
Tissues:specialised in a specific activity (muscular tissue…)
-
Organs:made up of different tissues. They carry out a task (the heart…)

The vital functions
All living beings carry out 3
vital functions: nutrition, interaction and reproduction.
-
The nutrition function: living beings obtain oxygen and the nutrients they need. Use substances in their bodies and eliminate waste.
-
Living beings obtain nutrients in two ways:
-
Heterotrophic nutrition (animals).
-
Autotrophic nutritions (plants).
-
Obtaining oxygen (from air or water)
-
Using substances(to grow and obtain energy).
-
Eliminating waste (they expel harmful substances).

The interaction function: living things react to changes:
-
Animals (sense organs, nervous system and locomotor system)
-
Plants (changes in light or water).
-
The reproduction function (offspring)
-
It can be asexual or sexual (male and female). Each one has different reproductive cells called gametetes.

The classification of living things:
-
There 5 kingdoms: Monera, Protoctista, Fungi, Plantae and Animalia.
