Cell Adaptation
To know how animal and plant cells
are adapted for different functions
D. Crowley, 2007
All Animal Cells
look the same
The cells of
different animal
cells are always
different
Animal cells
may look
different but
they all have a
nucleus
Some animal
cells look
different
because they
need to do a
special job
Recap
What parts of a cell are found within animal cells and
plant cells?
Animal cells: Nucleus
Cell membrane
Cytoplasm
Plant cells: All of the above +
Cell wall
Vacuole
Chloroplasts
Specialised Cells
Consider the root hair cell:
It is “suited” to its job of taking in
water and nutrients in 2 ways:
1) It has a large surface area
2) It has a thin cell membrane
The sperm cell is another example of a
specialised cell:
Strong tail for
swimming
Vacuole containing
enzymes
Animal Cells
Animal Cell
Cell
Diagram
Function
Specialisation
Red blood
cells
To carry oxygen
Large surface area for oxygen
Haemoglobin which binds the
oxygen
Nerve cell
To carry nerve impulses to different
parts of the body
Long
Connections at each end
Can carry electrical signals
Female
reproductive
cell
To join with a male cell, and then to
provide food for the new cell that
has formed
Large
Contains a large amount of
cytoplasm
Male
reproductive
cell
To reach the female cell in order to
join with it
Long tail for swimming
Head which is able to penetrate
the female cell
* Make the drawings as clear, and accurate as possible
Plant Cells
Plant
Cell
Cell Diagram
Function
Root hair
cell
To absorb water and
minerals
Leaf cell
To absorb sunlight (needed
for photosynthesis)
Specialisation
Large surface area
Large surface area
Many chloroplasts (containing
chlorophyll, needed for
photosynthesis)
