Specialized Cells Flashcards
A cell that has a particular structure and performs a specific function
Specialized Cells
True or False:
Each type has unique shape, size and features allowing it to do its job accurately
True
True or False:
all types of specialized cells has unique shape, size and features allowing it to do its job accurately
False
what cells have a variety of specialized cells
Plant cells
True or False:
Cells in the leaf of a tree have a different structure and function from the cells in the trunk.
True
True or False:
Cells in the leaf of a tree have the same structure and function from the cells in the trunk.
false
what cells are on young rocks that have hairs that absorb water from the soil
epidermal cells
True or False:
some plant cells transport water and dissolved minerals throughout the plant
true
True or False:
some plant cells transport chlorophyll throughout the plant
false
what cells contain many chloroplasts to collect energy from sunlight to make sugar for the plant
photosynthetic cells
true or false:
other cells transport dissolved sugars around the plant
true
true or false:
other cells do not transport dissolved sugars around the plant
false
what specialized cells have round edges to travel in blood vessels easier
red blood cells
why do red blood cells not have nucleus
to have more room to carry 02 and CO2
what specialized cells have long, skinny arms to send messages quickly over long distances
nerve cells
what specialized cells conduct electrical impulses to coordinate body activity
nerve cells
what specialized cells have cilia
ear cells
what are the tiny hairs on inner ear cells that pick up vibrations in the air and send signal to brain
cilia
what specialized cells have long, skinny cells that lengthen and shorten to move muscles
muscle cells
how are muscle cells arranged?
in bundles
what are muscle cells that are arranged in bundles
muscle fibers
what are the specialized cells that can contract which makes the fiber shorter and causes the bones to move
muscle cells
what specialized cells are the smallest cells in the body and millions of them are made
sperm cells
where are the enzymes contained in a sperm cell
in the head
what makes a sperm penetrate an egg
an acrosome in the head that contains enzymes
what does the head of a sperm cell contain
genetic material
what is the use of genetic material that is contained in the head of a sperm cell
for fertilization
what part of the sperm cell is the mitochondria found
middle
true or false:
The middle piece is packed with mitochondria to release energy needed to swim and fertilize the egg.
true
true or false:
The tail piece is packed with mitochondria to release energy needed to swim and fertilize the egg.
false
what enables the sperm to swim
the tail
what specialized cells help keep dirt out of the lungs.
trachea cilia
what does the orange goblet cells in the trachea cilia do
secrete mucus
what moves the mucus along the trachea to remove inhaled dust and dirt.
hair-like extensions or cilia
what specialized cells are unspecialized cells that divide quickly and do not have a particular function yet
stem cells
unspecialized cells
stem cells
these are the only specialized cells that can differentiate into many cell types.
stem cells
how many possibilities can a stem cell be
220 different cells
true or false:
The blood found in an umbilical cord immediately after the birth of a child is a rich source of stem cells.
true
true or false:
The blood found in the placenta immediately after the birth of a child is a rich source of stem cells.
false
where can stem cells be found in a baby
umbilical cord
these cells can develop into various kinds of blood cells.
stem cells
true or false:
The blood collected from the cord can be banked (or stored) in the event it is needed later in the child’s or a sibling’s life.
true
true or false:
The blood collected from the placenta can be banked (or stored) in the event it is needed later in the child’s or a sibling’s life.
false
what are the other uses of stem cells
for leukemia
to produce cancer-free blood cells
For diseases such as leukemia, how can stem cells that are collected from healthy blood be used
by injecting into a patient’s blood after the diseased cells have been killed
True or False:
The healthy cells then grow in the patient’s bone marrow and produce healthy, cancer-free blood cells.
true
True or False:
The healthy cells then grow in the patient’s capillaries and produce healthy, cancer-free blood cells.
false
