Question

directions: match each cell type to its function.

1. increased surface area to transport oxygen throughout the body.
2. contain a “reservoir” to store lipids and triglycerides for future use.
3. consists of a long axon and dendrites to transport electrical signals.
4. slow contraction allows these cells to contract for longer periods of time.
5. elongated cell found in the retina. acts as a photoreceptor for sight.
6. intercalated discs found in this cell allow for “wave - like” contraction
7. long, elastic fibers allow for contraction and movement.
8. found in the matrix of bone and acts as a “sensing system.”
9. structure allows for protection against bacteria and viruses.

a
b
immune cell
smooth muscle
c
d
neuron
fat cell
e
f
skeletal muscle
rod cell
g
red blood cell
h
i
cardiac
osteocyte

Explanation:

1. Red blood cells have a biconcave shape for increased surface - area to transport oxygen.
2. Fat cells store lipids and triglycerides.
3. Neurons have axons and dendrites for electrical signal transport.
4. Smooth muscle has slow contraction.
5. Rod cells in the retina are photoreceptors.
6. Cardiac cells have intercalated discs for wave - like contraction.
7. Skeletal muscle has long, elastic fibers for movement.
8. Osteocytes act as a sensing system in bone matrix.
9. Immune cells protect against bacteria and viruses.

Answer:

1. G. Red Blood Cell
2. D. Fat Cell
3. C. Neuron
4. B. Smooth Muscle
5. F. Rod Cell
6. I. Cardiac
7. E. Skeletal Muscle
8. H. Osteocyte
9. A. Immune Cell
