Explain your thinking. Describe the “rule” or reason you used to decide whether something is or
was once made up of cells.

Now that you know all of the parts that make up a general cell, it’s time to look at
specialized cells. Using what you know about what each part of the cell is responsible
for, design a cell that is well-adapted to perform the task written on the back of this
page.
• Think carefully about all the steps the cell will have to make in order to perform
the task.
• Think about the parts of a general cell that will be most important to your cell.
Draw your cell, labeling all the major parts.
Do not draw below this line.
*** If you get a sliver, this cell helps break down the wood now lodged in your finger ***
Describe how the features you gave your cell help it perform this task.

Describe how the features you gave your cell help it perform this task.
Design cells to perform the following tasks. Think carefully about all the steps the cell
will have to make in order to perform the task. Then think about the parts of a general
cell that will be most important to your cell.

Cell parts
Cell Structure
1. Cell membrane – separates cell from the outside
2. Cell wall – protection and support in plants, algae, some others
3. Nucleus – holds chromosomes
a. Nuclear envelope – separates nucleus from cytoplasm
b. Nucleolus – where ribosomes are made
c. Chromosomes – DNA molecules
4. Cytoplasm – everything between the nucleus and the cell membrane
Organelles
1. Mitochondria – convert stored chemical energy into compounds more readily
usable
2. Chloroplasts – site of photosynthesis
3. Ribosomes – assemble proteins
4. Smooth ER – storage of chemicals and enzymes
5. Rough ER – modification of newly made proteins
6. Golgi apparatus – modifies, collects, packages and distributes proteins
7. Lysosomes – break down foreign materials
8. Vacuoles – storage of water, starches, pigments, etc.
9. Cytoskeleton – support and movement
a. Microtubules – support cell shape, move organelles around
b. Microfilaments – cytoplasmic streaming
