Eukaryotic Cell StructureCells and Organelles
2.4 Notes
Domain: Eukaryote
• These cells all have a ___________!
Cell Structure:
• Most cells have the same basic construction; they are:– Surrounded by a ____________(like skin)
– Centered around a nucleus– Made up of various ______________• Organelle- miniature organs with specific functions.
Cell membrane
• Function: ______________what goes in and out of the cell– Nickname: “___________” on a window
Nucleus
• Function: Controls everything that happens in the cell.
• Holds ALL the DNA– Nickname: “___________” of the cell
Cytoplasm
• All the stuff _____________the cell membrane and the nucleus (including the organelles).
Mitochondria
• Function: Makes _____________ for the cell.– Nickname:• “_____________”
Chloroplasts (plants only*)
• Function: Makes energy for the cell through _____________.– It is _____________!• *some protists
• Nickname: – “_____________”
Lysososome
• Function: Storage for digestive _____________
• Nickname: “_____________” of the cell.
Endoplasmic Reticulum
SMOOTH Endoplasmic Reticulum
• AKA: “Smooth ER”• Function: Makes
_____________ and lipids (fats)
ROUGH Endoplasmic Reticulum
• AKA: “Rough ER”• Function: Makes, modifies
and _____________ proteins.
• Covered in Ribosomes (makes it look rough)
• Nickname (for both): “roads”
Ribosome
• Function: Makes _____________– Very _____________! All those little dots!– Not * _____________ * an organelle (but super
important)
Golgi Apparatus
• Golgi Apparatus = Golgi Body = Golgi Complex• Function: Stores, modifies and
_____________ stuff around the cell– Nickname: “_____________” truck
Vacuole
• Fluid-filled spaces• Function: _____________ _____________– In _____________ a few small ones– In Plants- ONE HUGE ONE!
Cell Wall
• IN ALL PLANTS! And some _____________ and bacteria.
• Function: Provides protection and support– Makes plants “_____________”
Centriole/Centrosome
• Animal Cells _____________– • Function: helps with cell division (making new
cells)
Cilia and Flagella
Cilia• Function: Lots of little
_____________ used for moving.
Flagella• Function: One or just a few
larger “_____________” used for moving
