Specialized Cells
D. Crowley, 2007
Specialized cellsAnimal and plant cells are adapted for different functions
The way the cell is formed depends on the job it must perform
ReviewWhat parts of a cell are found within animal cells and plant cells?
Animal cells: -NucleusCell membraneCytoplasm
Plant cells: -All of the above +Cell wallLarge VacuoleChloroplasts
Specialization
Many organisms are multi-cellular - they are made up of lots of cells, not just one!
Many of these cells are specialized, sharing the life processes (they work together as a team, supporting the organism)
Specialized cells occur in both animals and plants…
Animal CellsThe table below shows some specialized animal cells
Animal Cell Cell Diagram Function Specialisation
Red blood cells
To carry oxygen Large surface area for oxygen
Hemoglobin which binds the oxygen
Smooth, round to allow for travel through small vessels
Nerve cell To carry nerve impulses to different parts of the body
Long
Connections at each end
Can carry electrical signals
Skin cells To serve as a barrier between your body and outside elements
Like a brick wall…fit together edge to edge
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
Plant CellsThe table below shows some specialized plant cells
Plant Cell Cell Diagram Function Specialisation
Root hair cell
To absorb water and minerals Large surface area
Leaf cell To absorb sunlight (needed for photosynthesis)
Large surface area
Many chloroplasts (containing chlorophyll, needed for photosynthesis) located along edges of cell
Tissue Specialization
Tissue is a group of cells that works together to perform a specific function
Organ Specialization
Organs are composed of two or more types of tissue combined to perform a single task
Organs often contain several types of tissue
Ex: Heart is composed of muscle,connective,epithelium, and nervous tissue.
