The Cell
What are cells?
Your body is divided into tiny
sections called cells.
The cell is one of the most
basic units of life.
Cells are grouped together in
collections called tissues.
Cells
• There are cells that are organisms,
such as microscopic amoeba and
bacteria cells.
• There are cells that only function when
they are part of a larger organism, such
as the cells that make up your body.
Cell Types
• Bone Cell
Muscle Cell
• Nerve Cell
• Blood Cell
Small Intestine Cell
Cell Parts or areas:
All cells have three main parts:
• the cell membrane,
• the cytoplasm, and
• the nucleus.
Cell Membrane
Cell membrane
• The cell membrane surrounds the
cytoplasm of the cell.
• It acts as a boundary layer to contain
the cytoplasm (fluid in cell).
• It allows water, oxygen, and other
materials to pass in and out of cells.
Cytoplasm
cytoplasm
• Cytoplasm is the material between the
cell’s nucleus and the cell membrane.
• It fills the entire cell.
• It contains a large variety of organelles
and nutrients.
• It stores nutrients.
Nucleus
• The nucleus is the cell’s
command center.
• The cell’s nucleus contains the
cell's DNA, the genetic code.
Mitochondria
• The mitochondria provide
the energy for the cell.
