Engage: Warm Up1. List as many organs as you can think of
in your body.
2. Make a list of DIFFERENCES that you see between these two cells.

Get ready for “Cell Organelle Notes”
Organelles
• Organelle means “little
organ”
• Each organelle has a
specific job (function)
• All of them must work
together to keep the cell
alive
What is an organelle?
Plasma Membrane(cell membrane)
• Surrounds cell
(like a city wall
with gates)
• Controls what
goes in and out
of cell
Outside
Ribosomes
• Make proteins (like builders and workers)
• Can be floating in cytoplasm or attached to
the rough ER
Outside
Phytoplankton Up Close
Protoperidinium Pellucidum
Microbes, like this single-celled marine phytoplankton, make up a
staggering 90 percent of the ocean’s total biomass. Because such organisms are so difficult to observe in nature, much of the ocean’s microbial life remains a
mystery to science.
Prokaryotic or Eukaryotic?
ThalassionemaThis star-shaped colony of marine diatoms is called Thalassionema. Diatoms are single-celled algae and some of the most numerous photosynthetic “plants” in the oceans. Hundreds of diatoms can fit on the head of a pin, but these tiny organisms exist in countless numbers—enough to change seawater color during periodic population “blooms.”
Prokaryotic or Eukaryotic?
DinoflagellateA scanning electron microscope captured this pair of unicellular dinoflagellates in a drop of seawater found near the Opera House in Sydney, Australia. The microbes were later colorized to produce this image’s glowing, green hue. Scientists are just beginning to understand the impact such invisible organisms can have, for good or ill. Dinophysis species like these are associated with diarrhetic shellfish poisoning.
Prokaryotic or Eukaryotic?
Mitochondria
• Power supply for cell (like a generator)
• Provides energy by breaking down
carbohydrates
Vacuole
• Stores water, food, and waste (like a water tower)•small in animal cells•LARGE in plant cells
Ribosomes• Where protein
synthesis happen in the cell.
• Typically recognized by small dots unless it’s a close up.
Cell Membrane• Controls what goes
in and out of the cell.• Phospholipid bilayer
is made up of 2 layers (hydrophobic and hydrophilic)
• Made mostly of lipids with some proteins.
Chloroplasts(plants only)
• Power supply for plant cells (like a power plant)
• Convert light energy into chemical energy
• Contain chlorophylls (which make them green!)
Cell Wall(plant cells and bacteria cells)
• Gives structure and support to cell
• Made of cellulose (a carbohydrate!)

Evaluate• Fill in a diagram to compare and contrast
eukaryotes and prokaryotes. You may use your notes that you took during class.
OnlyProkaryotes
Only Eukaryotes
Both
• Create flash cards of the cell parts
• One side = name and drawing (picture)
• Other side = function (what it does)
Golgi Apparatus Packages, sorts and ships proteins
Prokaryotes make up bacteria.
Compete for the biggest list including:1. What are all the different places
that you could find prokaryotes (bacteria)?
2. What are infections caused by prokaryotes (bacteria)?.
3. Give names of prokaryotes (bacteria)?
Endoplasmic Reticulum
• Network of membranes that transport proteins (like streets and highways)
• Rough ER- contains ribosomes to make proteins
• Smooth ER- no ribosomes, makes lipids
Nucleus & Nucleolus
Nucleus:
• Control center (like City Hall)
• Contains DNA
Nucleolus:
• Inside of nucleus
•Makes ribosomes
