The Cell

• And Its Organelles

2
The Cell

• The basic unit of structure and function in
  living things

3
Organelles

• The tiny structures in the cell that carry out
  the specific functions in the cell

4
Entering The Cell

• CELL WALL
• A stiff wall that surrounds the cell membrane,
  giving the cell a rigid boxlike shape
• Function protection support
• This structure is only on the plant cell
• Biology4Kids.com Cell Structure Cell Walls

• CELL MEMBRANE
• Forms the outside boundary that separates the
  cell from its environment
• Function controls what comes in and out of the
  cell
• Biology4Kids.com Cell Structure Cell Membrane

5
CYTOPLASM

• A gel-like fluid found throughout the entire cell
  wherein the organelles are found.
• It is constantly moving so the cell does not need
  to propel itself.

NUCLEUS

• Description Acts as the brain of the cell or
  the control center. This is where the DNA is
  found.
• Function Directs all of the cells activities
• Biology4Kids.com Cell Structure Cell Nucleus

Nucleus
10
Ribosomes

• Description Ribosomes are the smallest
  organelles, but there are more in one cell than
  any other type of organelle.
• Function Factories that produce proteins.

ENDOPLASMIC RETICULUM

• Description Folded membranes that contain many
  tubes and passeways.
• Function Carry proteins and other materials from
  one part of the cell to another
• Biology4Kids.com Cell Structure Endoplasmic
  Reticulum

13
Endoplasmic Reticulum-aka ER
14
MITOCHONDRIA

• Description The powerhouses of the cell
• Function Produces energy for the cell
• Biology4Kids.com Cell Structure Mitochondria

Mitochondria
16
CHOLORPLASTS

• Description Found only in the plant cell
• Function Capture energy from the sunlight and
  use it to produce food for the cell
• Biology4Kids.com Cell Structure Chloroplasts

17
GOLGI BODIES

• Description The cells mailroom
• Function Receives proteins and other materials
  from the ER, packages them and distributes them
  to other parts of the cell.
• Biology4Kids.com Cell Structure Golgi Complex

Golgi Complex (Bodies)
19
LYSOSOMES

• Description Cells cleanup crew
• Function Breaks down old cell parts and releases
  the substances so they can be used again.
• Biology4Kids.com Cell Structure Lysosomes

21
VACUOLES

• Description Stores food and water. Plants have
  one large vacuole for water some animal cells
  have them others do not
• Function Storage area of the cell
