Transcript Animal Cells powerpoint

Materials Needed
Structures and Functions in Living Systems
graphic organizer-copy the notes that are
highlighted in green throughout the ppt.
The notes in blue will go on the back of
your worksheet.
 See slide #15, draw, label & color a picture of

an animal cell on the worksheet “Living Things
Are Made of These”, last page, question #8

Pencil, colored pencils
Cell Membrane (gatekeeper)
Semi-permeable
 Controls what enters and leaves the
cell
 Gas exchange
(similar function to
lungs in your body)

Nucleus (Brain/Control Ctr.)
Controls the activities of the cell
 Holds the genetic material (DNA)
Contains genes (made of DNA) on 46
chromosomes. Thousands of strands of
DNA can fit onto one chromosome. These
have all the instructions for your body.

Cytoplasm
Fluid that fills cells
 Site of many cellular reactions

Organelles – Units
in cells that have
different functions
http://www.enchantedlearning.com
Mitochondria (Powerhouse)

Site of respiration, where glucose is
broken down into cellular energy

Active animal cells have
more mitochondria
than plant cells
Vacuoles
Store food, water or wastes
 VERY small in animal cells. VERY large in
plant cells. Contains fluid.

Lysosomes (trash collector)

Used to digest food or dissolve wastes
(you don’t want it to burst)

Very common in animal cells but rare in
plant cells.

Ribosomes

Make proteins.

Found in cytoplasm and Rough ER.
Ribosomes are made up of two layers.

Endoplasmic Reticulum “ER”
Rough ER: Transports proteins (like a
highway). Has ribosomes.
 Smooth ER: Collects and stores
proteins.

Golgi Complex (factory)
Builds lysosomes
 Stores and packages proteins

Centrioles
Helps the cell divide.
 They can’t be seen when the cell is
not dividing.

Nucleolus

Produces ribosomes, which move out of
the nucleus to the rough ER
