Cell Biology – Structure ; Function of Organelles

Cell Wall
Outer layer of the cell that supports and protects the cell. Allows H2O, O2, and CO2 to pas into & out of the cell.

Cell Membrane
A thin, flexible barrier around the cell; controls what substances enter and leave the cell.

Contains DNA – The control center/brain of the cell.

Nuclear Membrane
Surrounds the nucleus; controls what goes in and out of the nucleus.

Gel-like fluid surrounding & protecting the cells organelles.

Endoplasmic Reticulum (E.R.)
A network of tubes that form a maze of passageways in which proteins ; other materials are carried from one part of the cell to another.

Rough Endoplasmic Reticulum
Endoplasmic Reticulum with ribosomes attached.

Smooth Endoplasmic Reticulum (Smooth E.R.)
Endoplasmic Reticulum that has no ribosomes.

Small bodies free or attached to E.R.; structure in which proteins are made.

Bean-shaped organelle that breaks down sugar molecules to produce energy.

A sac inside a cell that acts as a storage area. Stores food, water, and waste.

Small ; round; breaks down/digests food particles and waste.

Green ; oval shaped; captures sunlight energy ; converts it into chemical energy (sugar) in photosynthesis.

Helps maintain cell shape .

Golgi Apparatus
Membrane-bound structure; modifies ; packages proteins for transport to other organelles.

Cell organelle that aids in cell division in animal cells only.
