Students will review:
In this chapter, you'll learn the answers to questions including:
- What do living systems require in terms of free energy and the exchange of matter?
- How do feedback systems regulate growth, reproduction and dynamic homeostasis?
- What are the parts of a cell?
- How is energy transformed in living organisms?
- How does the process of cellular respiration or energy transfer occur in cells?
- Why is chlorophyll important during photosynthesis?
1. Living Systems Requirement for Free Energy and Matter
Free energy and matter are required by all living things in order to grow, reproduce, and maintain biological processes. Additionally, free energy and matter must also be recycled through the environment in order to remove dead material and allow for new growth.
2. The Environmental Requirements for Growth, Reproduction & Dynamic Homeostasis
Cells need to maintain internal environments that are different from their external environments in order to grow and reproduce. In this video lesson, you will understand some ways that cells can control their internal conditions to ensure proper biological functioning.
3. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis
In order to maintain specific internal conditions, organisms use feedback mechanisms. Feedback is essential to the regulation of internal environments, which allows for proper biological functioning.
4. Energy and Life: The Transformation of Energy in Living Organisms
While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
5. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
6. Chlorophyll: Absorbing Light Energy for Photosynthesis
Plants are clean, green, photosynthesizing machines. Using a specialized pigment called chlorophyll, plants are able to soak up energy from the sun and turn it into food. In this lesson, we'll start to learn why chlorophyll literally gets excited about a sunny day!
7. What is Dextrin in Food? - Definition & Chemical Formula
This lesson will introduce you to dextrin, a common food additive. It will cover the structure, chemical formula, types, and purpose of this thickening and preservative agent.
