cells performs active transport
and passive transport,
moves materials in and
out of the cell,
communication

RNA. Found in
cytoplasm or on the
endoplasmic reticulum

MITOCHONDRIA Location in the Supplies energy or ATP Both

cytoplasm, bean shaped for the cell through cell
respiration using glucose
and oxygen

smaller in animal cells water, wastes or enzymes

CHLOROPLAST Green structures that Captures sunlight and Plant

contain chlorophyll uses it to produce food
through photosynthesis

GOLGI BODY Small bags with tubes Packages and secrets Both
connecting them proteins for use in and
out of the cell

LYOSOME Small, round structures, Digests older cell parts, Both

containing enzymes food or other objects

CENTRIOLE Small cylindrical Used with the spindle Animal

apparatus during mitosis

Use the table above to fill in the chart

Complete the following table by writing the name of the cell part or organelle in the right-hand column that
matches the structure/function in the left-hand column. A cell part may be used more than once.

Structure/Function Cell Part

Stores material within the cell

Closely stacked, flattened sacs (plants only)

The sites of protein synthesis

Transports materials within the cell

The region inside the cell except for the nucleus

Organelle that manages or controls all the cell functions in a eukaryotic cell

Contains chlorophyll, a green pigment that traps energy from sunlight and gives
plants their green color

Digests excess or worn-out cell parts, food particles and invading viruses or
bacteria

Small bumps located on portions of the endoplasmic reticulum

Provides temporary storage of food, enzymes and waste products

Firm, protective structure that gives the cell its shape in plants, fungi, most
bacteria and some protests

Produces a usable form of energy for the cell

Packages proteins for transport out of the cell

Everything inside the cell including the nucleus

Site where ribosomes are made

The membrane surrounding the cell

Provides support for the cell, has two “subparts”

Name for the collection of DNA in the nucleus of eukaryotic cells

Consist of hollow tubes which provide support for the cell

Small hair-like structures used for movement or sensing things

Composed of a phospholipid bilayer

Longer whip-like structures used for movement

 Cell City Analogy

In a far away city called Grant City, the main export and production product is the steel widget. Everyone in
the town has something to do with steel widget making and the entire town is designed to build and export
widgets. The town hall has the instructions for widget making, widgets come in all shapes and sizes and any
citizen of Grant can get the instructions and begin making their own widgets. Widgets are generally produced
in small shops around the city, these small shops can be built by the carpenter's union (whose headquarters are
in town hall).

After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the
city. In order for a widget to be exported, the carts take the widget to the postal office, where the widgets are
packaged and labeled for export. Sometimes widgets don't turn out right, and the "rejects" are sent to the scrap
yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and
carts from a hydraulic dam that is in the city. The entire city is enclosed by a large wooden fence, only the
postal trucks (and citizens with proper passports) are allowed outside the city.

Match the parts of the city (underlined) with the parts of the cell.

In what organelle does cellular respiration take place?

Name two storage organelles?

What is the list of organelles that take part in protein synthesis?

How is the nucleus involved in protein synthesis?

What organelle is considered a “factory”, because it takes in raw materials and converts them to cell products
that can be used by the cell?

How does the membrane of the cell differ from the nuclear membrane? What advantages does this difference
have for the nucleus?

What do ribosomes do? Are they found freely floating in the cytoplasm? OR are they found attached to
another organelle? OR both. Explain why this occurs.
