What is a cell?
definition: a small compartment that holds all of the biological equipment
necessary to keep an organism alive

About cells…
Their main purpose is to organize.
They make up all living things.
Cells are alive!

Animal CellWhat is it?
• a form of eukaryotic cell
• makes up many tissues in animals
• many types (cheek, nerve, muscle, skin)

Plant CellWhat is it?
• a structural and functional unit of a plant
• different plant cells have different roles
• many types (parenchyma, collenchyma, sclerenchyma)

Animal Cells
• Nerve cells electrochemically send information between sensory receptors and the central nervous system.
Each type of animal cell is specialized to do different jobs.
dendrites
axon

Animal Cells
• Blood cells carry oxygen to the body’s tissues and collect carbon dioxide. They also carry hormones, enzymes, and vitamins to different parts of the body.
Each type of animal cell is specialized to do different jobs.

Animal Cells
• Muscle cells comprise the three different types of muscles: skeletal, cardiac, and smooth types. These cells are shaped differently and enable these muscles to help our bodies function properly.
Each type of animal cell is specialized to do different jobs.

Animal Cells
• Skin cells make up the tissue that covers our bodies. These cells are good at providing a barrier to the external environment and at preventing water loss.
Each type of animal cell is specialized to do different jobs.
