Life Science Midterm Study Guide 2017
Overview: This Study Guide is a compilation of all past study guides. You may use this to guide your studies in
addition to using past tests and study guides. I have also provided an additional study guide in a separate format
as an additional resource. You may also want to read through your notebook and high light important concepts
for review and create flashcards for major vocabulary and/or concepts. Some questions are not reviewed
specifically as they require you to use your knowledge of the subject and then apply it to the scenario given.
These will be discussed in class and you may take additional notes at that time.
1. Which Scientist experimented with Meat and Maggots?
2. Would life exist if our planet did not meet our 5 basic needs?
3. How many times must an experiment be successfully completed in order for it to be considered valid?
4. Science is__________________________________________________________.
5. The Scientist who finally disproved Spontaneous Generation was __________________
6. Memorize the Cell Theory.
7. What are plants and animals made of?
8. Review your notes packet. What are some differences between plant cells and animal cells? Do all cells have
a cell well? Do all cells have a nucleus?
