Eukaryotic Cell Structure Cells 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 ROUGH Endoplasmic Reticulum • AKA: “Smooth ER” • Function: Makes _______ and lipids (fats) • 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 Flagella • Function: Lots of little _______ used for moving. • Function: One or just a few larger “_______” used for moving

Quick Review • Which organelle is the control center of the cell? Nucleus • Which organelle holds the cell together? Cell membrane • Which organelles are not found in animal cells? Cell wall, central vacuole, chloroplasts • Which organelle helps plant cells make food? Chloroplasts • What does E. R. stand for? Endoplasmic reticulum
