  2. Announcements • Essay Due: 3:30pm: Turnitin.com • 7828230 ID for 2nd Period: Password: PRIDE • You can share a copy with me as well • Email, • Google Docs • Hard copy • Exams back by Wednesday • Projects are still being worked on • I underestimated how long it would take

  3. Tape Chapter 6 Exam Create your new Notebook Title Page Update Toc: Engage: “What’s Going On Inside a Cell?” Chapter Seven Cells Are Busy Places

  4. Chapter Questions • Where does the carbon in your body come from? • What is photosynthesis? Where does it occur? How does it occur? • Where does plants and animals get their energy from? • What is cellular respiration? • What happens to the food we eat? Does it really go “straight to your hips?” • Why is the sun so important to life on Earth? How does light give energy?

  5. Learning Target • I can understand how plants get energy and matter for growth • Before: (rate your level of understanding) • After: (After the lesson is complete)

  6. Engage: What’s Going On Inside a Cell? Take a deep breath and hold it. We’ll time it and see who can hold their breath the longest. Why did we do that? Why can’t we hold it for a very long time? Do plants breathe? Chapter 7

  7. Engage: What’s Going On Inside a Cell? True or False: Plants absorb their food from the soil? False! Plants MAKE their own food through photosynthesis. Carbon dioxide in the air plus water and nutrients in the soil, plus energy from the sun are the necessary ingredients for plants to make their food. Plant Roots Absorb Water & Nutrients

  8. Engage: What’s Going On Inside a Cell? Multiple Choice: choose all that apply… Plants need the sun’s energy to stay warm. Plants convert the sun’s energy into food energy Food energy is chemical energy Chemical energy is potential energy. A, B, C and D. Plants Need The Sun to Live

  9. Engage: What’s Going On Inside a Cell? Multiple Choice: choose all that apply… A) Animals use respiration to exchange oxygen and CO2. B) Plants photosynthesize but do not use respiration. C) Plants take in CO2 and expel oxygen. A and C Why is B false? Respiration is not “breathing”. Respiration is more accurately called cellular respiration, which occurs at the microscopic level and is a gas exchange. Plants exchange gases – they use carbon dioxide to make food and expel oxygen as a by-product. So, plants do ‘respire’! Animals take in Oxygen and expel Carbon Dioxide

  10. Engage: What’s Going On Inside a Cell? Cellular Respiration Physiological Respiration (often confused with breathing) is defined as the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction. This is in contrast to the biochemical definition of respiration: Cellular respiration is defined as the metabolic process by which an organism obtains energy by chemical reactions. Physiologic respiration is needed to sustain cellular respiration and therefore life, but the processes are distinct: cellular respiration takes place in individual cells while physiologic respiration is the transport between the organism and the external environment. Cellular respiration is a set of metabolic processes in cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. It might use oxygen (aerobic) and it might NOT use oxygen (anaerobic).

  11. Engage: What’s Going On Inside a Cell? Engage Process/Procedure: • Page 320 Process Write 1 paragraph answering the following question: • 1b. What do you think happens at the cellular level to allow a geranium to grow from a small plant to a large one? Or a maple seedling to a towering tree? • Also answer c, d, and e Homework answer the following questions: • What was the point of holding our breath at the beginning of class? • Why can’t we hold it for a very long time? • Do plants breathe?
