Transcript Cells 2 Quail

Questions of the Day
• Eukaryotic or Prokaryotic?
Prokaryotic or Eukaryotic?
Prokaryotic or Eukaryotic?
Prokaryote or Eukaryote?
Goals for the Day
1. Learn the basic functions of Eukaryotic cell
organelles
2. Be able to separate organelles as belonging
to plant cells, animal cells, or both.
3. Be able to separate organelles as belonging
to Prokaryotes or Eukaryotes
Question
What cell organelles (parts of a cell) have you
heard of before? List as many as you can
think of.
Cell Organelles
• Organelles – Organs for cells
• Nucleus
• Controls all cell activities
• Contains DNA
Eukaryotic Cells
Eukaryotic cells have:
• A nucleus which contains the cell’s DNA
• Other internal compartments called
organelles.
Nucleus of a Cell
The Nucleus, continued
Ribosomes and the Endoplasmic Reticulum
•
•
•
•
•
•
Endoplasmic Reticulum (ER)
Transportation
Two kinds:
Rough and Smooth
Rough has ribosomes- makes/transports
proteins
Smooth makes/transports lipids
Endoplasmic Reticulum
The ER moves proteins and other substances within eukaryotic cells.
Golgi bodies
Golgi bodies
Storage and Packaging
The UPS of the cell
Lysosome
• Lysosomes- small, spherical organelles that
contain the cell’s digestive enzymes
• Function: Digestion & Recycling
(The garbage man of the cell)
Structures of Plant Cells
Plants have three unique structures that are not
found in animal cells:
• Cell Wall
• Chloroplasts
• Central Vacuole
Structures of Plant Cells
•
Cell Wall –surrounds the cell membrane of plant
cells, and is made of proteins and carbohydrates.
Functions of the Cell Wall:
• helps support and maintain the shape of the cell
•
protects the cell from damage
•
connects the cell with adjacent cells
Structures of Plant Cells
•
Chloroplasts convert light energy into USABLE
energy
Mitochondria
Mitochondria (Powerhouse of the cell)
Convert sugar into usable energy (ATP)
Where in your body would you need a lot of
mitochondria?
Mitochondria, continued
Mitochondria have an inner and an outer membrane.
Mitochondria & Chloroplasts
• Unique features of the mitochondria &
chloroplast:
• Both are energy-related organelles
• Have two membranes
• Have their own DNA
• Reproduce separately from the cell
Structures of Plant Cells
Central Vacuole:
• Takes over the function of the Lysosome,
which is not found in plant cells!!!
• Why might plants want to retain toxins and
wastes inside the cell???
Comparing Plant and Animal Cells
Organelle Billboard
• Imagine you are in charge of marketing for a
particular cell organelle. You will make a
billboard that represents the shape of your
organelle. On the back side of the organelle
you will need to come up with a marketing
slogan that represents the function of the
organelle, and finally a simile about what your
cell organelle is like, this should also have
something to do with its function.
Organelle Marketing
•
Once you have completed your organelle, slogan,
and simile, determine what organism groups your
organelle would be found in.
• prokaryotes, eukaryotes, both
• Plants, animals, both
You will need to include this information in
your presentation
• You may earn extra points by
developing a slogan and simile for the
cell membrane and cell wall
