Red Blood Cells
Red blood cells main job, or function, is to take in oxygen as blood passes by the lungs, and then travel along in
the bloodstream to deliver that oxygen throughout the body to all the body tissues.
How does the structure of a red blood cell help it do it’s job?
Structure
Function
Disk Shaped, Flattened and Smooth
Can easily pass through small blood vessels
Flexible
Can squeeze through narrow blood vessels
Don’t have a nucleus
Leaves more space to carry oxygen
Fat Cell (Lipocyte)
Fat cells main job, or function is to store extra fat in the body until it is needed by the body as a source of
energy.
How does the structure of a fat cell help it do it’s job?
Structure
Large, round, empty looking
Function
Has plenty of room to store fat when there is an
excess.
Nerve Cells (Neurons)
A nerve cell’s main job is to quickly relay information to and from the brain. They sense stimuli in the
environment and send the information to the brain. Then they send a signal from the brain back to the body so
that the body can respond to the stimuli.
How does the structure of a nerve cell help it do it’s job?
Structure
Function
Long, thin branching arms
Lets messages move rapidly over longer distances
Many branches connecting to other nerve cells
Allows cells to pass messages in a chain form one to
the next.
Skin Cells
Skin cells cover your entire body and also line body cavities. The skin plays a key role in protecting the body
against invaders and excessive water loss. Its other functions are insulation, temperature regulation,
sensation.
How does the structure of a skin cell help it do it’s job?
Structure
Function
Very thin, flat, and overlapping
So gases can pass through, and overlapping for
protection
Contain a lot of keratin( a protien that provides
strength and support)
Makes it strong for protection
Sperm Cells
Sperm cells main job is to carry genetic material from the father, and deliver it to the egg during fertilization.
This way the offspring gains genes from both of its parents. It swims through the female reproductive tract
until it finds the egg.
How does the structure of a sperm cell help it do it’s job?
Structure
Function
Have a long flagellum (tail)
To help it swim up the female reproductive tract to
meet the egg
Have a pointed tip (head)
To help it push into the egg through the eggs cell
membrane
Muscle Cells
The main job of muscle cells is to contract, or shorten in order to produce movement. They may contract to
move your body, or pump your heart, or move food along your digestive tract.
How does the structure of a muscle cell help it do its job?
Structure
Function
Long and narrow
So that they can pack closely together, and then
shorten and relax to produce movement.
Guard Cells
When you get hot, you sweat, and when you sweat, water comes out of your skin through pores
called sweat glands. Plants also 'sweat' through a process called transpiration, and the plant's
pores, which are found on the leaves, are called stomata.
How do plants keep from losing all their water through stomata? Surrounding each stomata are
two guard cells, which regulate the opening and closing of stomata to facilitate gas exchange
and control transpiration in plants..
Structure
Flexible
Curved Shape
Function
Regulates movement water and gases
into and out of the plant cell
Has Vacuoles
Aids in photosynthesis
