Ch 16: ASVAB: Respiration & Photosynthesis
About This Chapter
ASVAB: Respiration & Photosynthesis - Chapter Summary
Check out these videos on energy creation and transfer as well as chemical and light reactions within plant cells to help you get ready for the ASVAB General Science test. The videos are taught by experienced science educators and contain engaging graphics and examples to hold your attention and maximize retention of key concepts. As you work through these lessons, you will enhance your knowledge of:
- Cellular respiration
- Chloroplast structure
- Photolysis and light reactions
- Photosynthesis: dark reactions
After you watch each video, be sure to check out the lesson transcript for a quick review of key terms and concepts which will be set in bold type for quick identification. Use the lesson quizzes and chapter test to gauge your readiness to answer similar kinds of questions during the actual test.
ASVAB: Respiration & Photosynthesis Chapter Objectives
The General Science test is one of several subtests you'll take during the ASVAB. The content of these lessons will prepare you for any questions which may be asked about what's going on in the cells of plants. You will only face 16 or 25 questions over 8 or 11 minutes in the General Science test (depending on whether you are administered a paper test or computer test).
The test covers material from every kind of life and physical science class you might have taken (or not) in high school, excluding most physics topics which are covered in other tests. This means that you will not likely face more than a couple of questions regarding plant cells, but also that we cannot guess at exactly what those questions might cover because there are several test versions and possible questions. But as you work through these lessons, you can become prepared to answer anything that comes up about cells in plants.
Talk to your local recruiters to schedule an appointment to take the ASVAB and find out whether you will take the paper or computer test. It may help to complete the course exam and chapter quiz before reviewing every video to get an idea of which areas you may need the most help in, focusing your time on those areas first. Work through this chapter and the other chapters in this study guide to make sure you have the most possible occupational options should you choose to join the military.
1. Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana
Photosynthesis occurs inside plant cells in tiny structures called chloroplasts. Learn about chloroplast structure and some of its important components including chlorophyll, the stroma, thylakoids, and grana.
2. Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products
The process of photosynthesis includes photolysis, the light reactions that use energy from sunlight to split water molecules. Learn about the steps, reactants, and products involved in photolysis and understand how to define this oxygen-producing process.
3. Dark Reactions of Photosynthesis: The Calvin-Benson Cycle
In the beginning of the photosynthesis process, sunlight energy is necessary. But photosynthesis progresses to dark reactions, known as the Calvin-Benson Cycle, to complete the process of sugar production. Learn about the steps in this cycle, including how the process uses carbon dioxide, ATP, and NADPH to create sugar.
