This 9-minute video lesson looks at how CAM Plants are able to fix carbon at night so they don't have to keep their stomata open during the day. [Biology playlist: Lesson 34 of 71].
The Biology Faculty is a new, free educational resource for secondary schools and especially those A-level students thinking about applying to University. We have a growing library of short, downloadable films of university lecturers speaking on topics from the A-level curriculum
The Biology course is a first-year course in biology at the high school level and involves the scientific study of living organisms. The course considers the interactions among the vast number of organisms that inhabit planet Earth. It presents the basic form and function of these organisms, from cells to organ systems, from simple viruses to complex humans. It delves into interactions between organisms, and between an organism and its environment. It also looks into how biotechnology is used to improve our health and daily lives.
- Understand the form and function of microorganisms
- Understand the form and function of plants
- Understand the form and function of animals
- Understand the workings of human biological systems
- Understand biology as it relates to the Earth's environment

In this course, you will learn the basics of plant biology. The student will begin with plant anatomy, learning the names and functions of all of the parts of a plant, then move on to plant physiology, where you will learn about photosynthesis, growth, and reproduction. Next, the student will study plant evolution according to the fossil record and examine the diversity of plant life in existence today and how that diversity impacts global ecology. Upon successful completion of this course, the student will be able to: identify and describe the functions of the different cells, tissues, and organs that make up a plant; describe the major life processes in plants (photosynthesis, respiration, transpiration, growth and development, and reproduction) at the tissue, organ, cellular, and molecular level; explain the history and evolution of plants on earth; discuss plant diversity and identify the major characteristics of plant phylogenetic divisions; explain how plants fit into the global ecological system and why they are essential for life on earth. (Biology 306)
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of central tendency of the class data, and then graph and interpret the results.
Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology I - Honors FlexBook covers Cell Biology, Genetics, Evolution, Ecology, and Physiology.
Students are introduced to the concept of energy cycles by learning about the carbon cycle. They will learn how carbon atoms travel through the geological (ancient) carbon cycle and the biological/physical carbon cycle. Students will consider how human activities have disturbed the carbon cycle by emitting carbon dioxide into the atmosphere. They will discuss how engineers and scientists are working to reduce carbon dioxide emissions. Lastly, students will consider how they can help the world through simple energy conservation measures.
This exercise introduces students to concepts of photosynthesis at the whole organism level and to computer utilization in biology. Changes in carbon dioxide concentration are measured in environmental chambers using gas analyzers connected to computers. Carbon dioxide changes are graphed in real time as the plants take up CO2. Over a short time, sunflower seedlings show dramatic changes in CO2 uptake when light intensity is altered or color filters are used. Comparison of the resulting graphs will indicate treatment differences in the rate of carbon dioxide change. Modifying the basic experimental design allows this exercise to be used in a variety of courses.
Through a reading, demonstration stations, and completion of a puzzle, students will recognize how respiration and photosynthesis move carbon through the earth system, how fossil fuels were formed, and how human activities have altered this movement on a global scale.
In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. The third lesson continues the students' education on cells in the human body and how (and why) engineers are involved in the research of stem cell behavior.
