1.1.3 What are
specialized cells
and how does
their shape
relate to their
function?

Specialized Cells SURE TO
Stem Cells
FILL IN*
Nerve Cells
Specialized Function: to carry electrical impulses
from the brain to different parts of the body
Shape: Elongated (travel long distances) and
Dendrites (make connections to other cells)
Sperm Cell
Function: fertilizes the female egg, provide the genetic
information from the male
Shape: Flagella (to swim), streamlined (enhance speed),
high concentration of mitochondria (energy), DNA
(from male)
Red Blood Cell
Function: carries oxygen to various parts of the
body via the protein hemoglobin
Shape: Round, bicave (surface area for oxygen
to bind), no nucleus (maximize room for oxygen)
Muscle Tissue
Function: allows for movement in the
body, specialized for contracting and
electrical conductivity
Shape: elongated for contraction
Xylem Cells
Function: Small tubes that carry water from the roots
to the leaves
Shape: Long and resemble tubes, no ENDS to cell walls
(allows for continuous flow of water)
Root Hair Cell
Function: absorbs water and other minerals from the
soil to provide for the rest of the plant
Shape: Thin cell walls (makes water uptake easier),
finger like projections into soil (increases surface area
for more efficient uptake of water and ions)
Leaf Cell
Function: absorbs light and conducts photosynthesis
Shape: cells are closely packed together (maximize
absorption), high number of chloroplasts
KEY POINT
Cell specialization (the specific function)
determines the shape of the cell and the
organelles present.
*FUNCTION and SHAPE are related*
