The Cell

1
The Cell

• And Its Organelles

2
The Cell

• The basic unit of structure and function in
  living things

3
PLANT CELL
ANIMAL CELL
4
Organelles

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

5
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

• CELL MEMBRANE
• Forms the outside boundary that separates the
  cell from its environment
• Function controls what comes in and out of the
  cell

7
NUCLEUS

• Acts as the brain of the cell or the control
  center
• Directs all of the cells activities
• Where DNA is found

8
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.

9
MITOCHONDRIA

• The powerhouses of the cell
• Produces energy for the cell

10
ENDOPLASMIC RETICULUM

• Carry proteins and other materials from one part
  of the cell to another
• RIBOSOMES
• Factories that produce proteins

11
GOLGI BODIES

• The cells mailroom
• Receives proteins and other materials from the
  ER, packages them and distributes them to other
  parts of the cell.

12
VACUOLES

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

13
LYSOSOMES

• Cells cleanup crew
• Breaks down old cell parts and releases the
  substances so they can be used again.

14
CHLOROPLASTS

• Capture energy from the sunlight and use it to
  produce food for the cell
• Found only in the plant cell

15
BACTERIAL CELLS

• Smaller than plant/animal cells
• Prokaryotes lack a nucleus. The genetic info is
  in the cytoplasm
• Have ribosomes and cell walls, but none of the
  other organelles
