The basic unit of structure for all
living things!
Theory – well tested hypothesis.
1.All living things are made up of cells.
2.Cells are the basic unit of structure
and function in living things.
3.New cells come from existing cells.
Prokaryotic Cell –
cells that lack a
membrane bound
nucleus.
Example: Bacteria
Eukaryotic Cell – a cell that contains a
membrane bound nucleus and many
specialized structures called organelles
“tiny organs”
Single Celled – organisms made up of 1
cell (ex. amoeba, paramecium, euglena)
Multicellular – organisms
made up of many
independent cells working
together (plants and animals)
Plant & Animal Cells
Function – protection & controls
what enters and leaves cell.
Structure – double layered
Phospholipid membrane
Function – holds all organelles
and nutrients.
Structure – semi-solid fluid (water,
proteins, various nutrients)
Function – Protects the DNA
Structure –
phospholipid
membrane (nuclear
envelop) & internal
fluid called
nucleoplasm.
Function – constructs lipids and
special proteins (enzymes) for
detoxification
Structure – folded
phospholipid
membrane
Function – modifies proteins
and packages them to be
shipped out.
Structure –
phospholipid
membrane
found in
stacks.
Function – power house of cell –
place where food is broken down
and turned into energy.
Structure –
phospholipid
membrane
Plant Cells Only
Function – makes food (sugars)
Structure – phospholipid
membrane
Function – protection and support
Structure – cellulose (carbs.)
Groups of similar cells working
together.
1. Epithelial Tissue – covers
interior and exterior body
surfaces.
Skin
2. Connective Tissue –
provides support for the body
and connects all of its parts.
3. Nervous Tissue – transmit
nerve impulses throughout the
body.
4. Muscle Tissue – enable the
body to move.
Groups of similar tissues
working together.
Groups of similar organs
working together.
Function – relays
messages from one
part of the body to
another
Structure – brain, spinal
cord & peripheral
nerves
Function – serves as a barrier
against infection
Structure – skin
Function –
brings oxygen in
and carbon
dioxide out.
Structure – nose,
trachea, pharynx,
bronchi and lungs
Function – converts
foods into
molecules that can
be used by body.
Structure – mouth,
esophagus,
stomach, and
intestines
Function –
Eliminates waste
products
Structure – skin,
lungs, kidneys
urinary tract
Function – supports
body,allows
movement and
produces blood
cells.
Structure – Bones
Function –
allows body to
move.
Structure –
smooth muscle,
cardiac muscle &
skeletal muscle.
Function –
brings oxygen,
nutrients, and
chemical
messengers to
cells.
Structure – heart and blood
Function –
regulates &
controls the
bodies functions
Structure –
glands
Function – produces sperm & egg
cells.
Structure –
testes & penis;
ovaries,
fallopian
tubes, uterus
and vagina.
Function – protects the body from
disease.
Structure –
white blood
cells and
lymph nodes
