Cell Theory & Structure

The organelle that forms a layer surrounding the cell; controls what goes in and out of the cell.

Labeled "K" on the diagram

• nucleus

• mitochondria

• cell membrane

• cytoplasm

The organelle that is a jelly-like substance that fills the cell; holds other organelles in place.

Labeled "D" on the diagram

• cytoplasm

• smooth ER

• lysosome

• golgi body

The organelle which contains most of the genetic information and controls all of the cells activities.

Labled "F" in the diagram

• nucleus

• mitochondria

• chloroplast

• ribosome

The organelle that provides the energy needed to power the cell; the powerhouse of the cell.

Labeled "C" in the diagram.

• mitochondria

• chloroplast

• rough ER

• lysosome

The organelle that acts as a storage center for the cell.

Labeled "C" in the diagram

• vacuole

• lysosome

• ribosome

• rough ER

The organelle that connects molecules together to make proteins; the smallest organelle in the cell. Floats freely in the cell or attaches to the rough ER.

Labeled "H" in the diagram.

• ribosome

• lysosome

• golgi body

• chloroplast

The organelle that modifies and transports proteins. Acts like a highway in the cell.

Labeled "G" in the diagram

• Endoplasmic Reticulum (ER)

• golgi body

• lysosome

• cytoplasm

The organelle that acts like the post office of the cell. It receives proteins from the ER and then sends them to the right place in or out of the cell.

Labeled "D" in the diagram.

• golgi body

• lysosome

• mitochondria

• ribosome

An organelle found only in plant cells. It makes food through photosynthesis, converting sunlight energy into sugar; green in color.

Labeled "A" in the diagram

• chloroplast

• mitochondria

• ribosome

• cytoplasm

An organelle found only in plant cells. A rigid outer barrier that supports and protects the cell.

Labeled "I" in the diagram

• cell wall

• cell membrane

• cytoplasm

• nucleus
