Cells: The Basic Units of Life
Typical Cells
Typical Animal Cell
Types of Cells
Cells come in all shapes and sizes for different functions in an organism. We call them
A collection of that performs a specific function.
A collection of
A collection of
What Are Living Things Made Up Of?
They are all made up of
Cells are so small you'd need a microscope to view them!
What Controls a Cell?
of a cell is its
control centre.
Within the Nucleus...
Made up of DNA.
Controls how the cell works.
Passed on from parents to children.
Responsible for what an organism will look like
Each chromosome contains many genes.
Each gene has instruction for individual characteristics.
A collection of
specialized cells.
Nerve Cell
Guard Cell
Muscle Cell
Transmits nerve signals in animals
Allows exchange of gases in leaves
Allows for movement of hands and legs
identical cells
different tissues
that performs a specific function.
Contains photosynthetic and vascular tissues
different organs
that performs a specific function.
Contains nervous and connective tissues
Typical Plant Cell
Animal Cell
Cell Membrane
Controls cell activities and contains chromosomes
A partially permeable layer that allows
some substances to pass through and
not others
A jelly-like substance that contains water
and other substances for chemical reactions
Small structures containing air, liquid and food
Cell Wall
Large Central Vacuole
Cell Membrane
Made of cellulose, a tough substance
that supports the cell and gives it a regular shape.
Contain a green pigment called chlorophyll, which absorbs light and uses it to make food.
Contains a liquid called cell sap and keeps the cell firm. Contains water, salt and sugar.
different systens
as a single living unit.
Work can now be divided among the various systems, organs and tissues.
This is known as
division of labour.
Nerve Tissue
Skeletal System
just one cell!
There is no division of labour.
Some organisms are made up of
