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 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

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
