Chapter 3 Test
Review
1. State the function of each of
the following parts:
• Cell Membrane – allows material to enter
and leave the cell
• Mitochondria – take food and releases
energy for the cell
• Cytoplasm – jelly-like substance in the cell
membrane
• Nucleus – directs all cell activity
1. State the function of each of
the following.
• Cell wall – protects the plant cell and gives it
shape
• Golgi Bodies- flattened materials that package
cellular substances and sent them out
• Organelles – structures within the cytoplasm of
eukaryotic cells
• Lysosomes – contain digestive chemicals to
breakdown waste
• Vacuoles – membrane bound space for temporary
storage in cells
2. State the Cell Theory
• All cells come
from other cells
that already exist.
3. What are the differences in an
animal and plant cell?
• Plant Cell
– Has a cell wall
– Has chloroplast
• Animal Cell
– Do not have cell
walls
– Do not have
chloroplast.
4. Know the organization of all
living things (start with the cell).
•
•

•
•
Cell
Tissue
Organ
Organ System
Organism
• Cell is the smallest
unit of an organism.
5. What is tissue?
• A group of cells
that work
together to do
one job.
6. What is an organ system?
• A group of organs
working together to
perform a certain job.
7. What is the definition of a
prokaryotic cell? Give an example.
• Cells found only
in one – celled
organisms.
• Bacteria
8. The ______ is usually the
largest organelle in the cell.
• Nucleus
9. Explain the difference
between eukaryotic and
prokaryotic cell.
• Eukaryotic Cells
– Found in many celled
organisms that contain
organelles.
– Have a membrane
bound structure.
• Prokaryotic Cells
– A one celled organism
that does not contain
organelles. Found in
bacteria.
– Do not have a
membrane bound
structure.
10. What is one difference
between one celled organisms
and cells that make up an organ?
• Single celled –
perform all their
life functions by
themselves.
• Organ cells –
work together
and depend in
some way on
other cells.
Be able to label a plant and
animal cell.
