Transcript Cell Organelles

Cell Organelles
• A cell is like a factory. It
has many machines
inside to make it work
correctly.
• The “machines” in a cell
are called organelles
• Organelles perform
functions to keep a
cell healthy and
alive.
• They are similar to
organs which
perform functions
to keep a body
healthy and alive.
Nucleus-control center of
the cell
•Nuclear membrane –
outer covering of the
nucleus, protects the
nucleus
• The Nucleus
contains
chromosomes
with DNA.
• The DNA
determines the
cell’s activities.
• The DNA
determines an
organism’s traits.
Cell membrane – outer covering of
the cell
• Jobs of membrane:
1. Protection
2. Selectively
Permeable – Controls
what goes in and out
of cell.
Cytoplasm – jelly like liquid
that holds all of the
organelles
Mitochondria
Power House”
of the cell.
• “
• Supplies the
cell with ATP
energy
Ribosome
• Produces
proteins
Vacuole – storage bins
Stores water and waste
materials
Golgi Bodies
• “Packing and
Shipping”
• Pack and ship
materials to
other parts of
the cell
Endoplasmic Reticulum
“Intracellular
Highway”
• Transport tubes
• Pathway of
tubes that carry
substances in
the cell
Plant Cells
• Plant cells have 3 parts that
animal cells do not.
• 1. Cell wall
• 2. Chloroplast
• 3 Large Central Vacuole
Cell Wall
• Outer rigid
protective layer
of a plant cell
• The cell wall is
outside of the
cell membrane
Chloroplast
• Has chlorophyll
• Performs
Photosynthesis
