How are plants organised?
Living things
Plants are organised in a similar way to animals and other
multicellular organisms. They have cells, tissues, organs
and systems.

Systems
Systems are groups of organs and tissue
that work together to carry out a function.
For example, flowers and pollen are part of
the reproductive system of flowering plants.
They enable the plant to reproduce.
Cells
Plant cells have a rigid cell wall,
so they are usually rectangular
or polygonal. Photosynthesis
takes place in leaf cells.
Those cells contain a green
liquid called
chlorophyll
and
a liquid called sap that is used
to make food for the plant.
Organs
Organs are made
up of tissue. A
leaf is an organ.
Its function is to
absorb sunlight
and carbon
dioxide. It needs
both in order to produce food for the plant by
photosynthesis.
Tissue
Plant tissue, like animal tissue,
is made up of many cells joined
together. This is leaf tissue.
