A. Cell Wall – A rigid and strong wall that protects and maintains the shape of
the cell.
B. Cytoplasm – All organelles of a cell reside in the cytoplasm.
C. Nucleus – The nucleus is the controlling center of a cell. It also contains the
DNA for the cell.
D. Nucleolus – Located inside the nucleus, the nucleolus produces RNA in the
form of ribosomes.
E. Chromatin – Part of the nucleus that contains most of the DNA of the nucleus.
F. Chloroplast – An organelle that contains chlorophyll, which makes up the
green substance in plants, and is where photosynthesis takes place.
G. Golgi Apparatus – Prepares proteins and fats that are created in the
endoplasmic reticulum for transport to the outside of the cell.
H. Mitochondria – The main energy source for a cell. The mitochondria converts
oxygen and nutrients into energy for the cell to use.
I. Ribosome – Some ribosomes are attached to the rough ER and are composed
of RNA.
J. Smooth Endoplasmic Reticulum (Smooth ER) – The smooth ER transports
materials throughout the cell, produces membrane proteins and digests lipids.
K. Rough Endoplasmic Reticulum (Rough ER) – Covered with ribosomes, the
rough ER produces protein and transports materials throughout the cell.
L. Cell Membrane – The cell membrane holds all the parts of a cell. Every cell is
enclosed by a cell membrane, which controls the passage of materials in and
out of the cell.
M. Vacuole – Most plant cells only have one large vacuole. It is filled with fluid
and helps to maintain the shape of the cell.

Interesting Cell Facts
• All life is dependent, directly or indirectly, on plants because of the energy
produced by photosynthesis in the cells.
• When a plant is watered, the water collects in the vacuole of the plant cells.
This helps the cells to stay rigid, which keeps the plant from wilting. The
vacuole then helps maintain the shape of the plant.
• The cell wall also helps give the plant its shape and keep it rigid.
• The color of flowers comes from pigments that are also contained in
the vacuole.
• The green color in plants comes from chlorophyll.

Photosynthesis
The process of photosynthesis is essential to sustaining life in plants and to all
other life on Earth. Without this process, plants would not have food and we
would not have oxygen.
Photosynthesis begins with the sun. Sunlight, water, and carbon dioxide are
absorbed by the chlorophyll found in plant cells. The sunlight, water, and carbon
dioxide then transform into sugar for the plant’s food and oxygen that will be
released into the air.

Suggested Activities
• Use for classroom demonstration as well as individual student exploration.
• As an introduction to cell structure, place the Giant Magnetic Plant Cell on
your whiteboard and label organelles as you discuss them.
• Place the cell structure on the board with the organelles off to the side. Invite
students to name the organelles. If students are correct, put the organelles on
the cell in the approximate place where they belong.
• Pass out the organelles to the students. Call out characteristics such as, “Filled
with fluid,” or “Helps the plant keep its shape.” Then, have students who are
holding organelles with those characteristics stand up and identify the
organelles.
• Have students label organelles either within the cell or individually on the
whiteboard.
• Assign each student in a group an organelle. Then, have the students work
together to create a “performance” showing how the organelles work
together. Allow them to perform for the class as a demonstration.
