Difference between Photosynthesis and Cellular Respiration.

Students learn how organic molecules move and are transformed in ecosystems as a result of the trophic relationships in food webs, photosynthesis, cellular respiration, and biosynthesis. This provides the basis for understanding carbon cycles and energy flow through ecosystems. In the final section, students use these concepts and quantitative reasoning to understand trophic pyramids. (NGSS)

Cellular Respiration and Photosynthesis are the processes of gas exchange by plants and animals.

Hello,
Thanks for the great resources. I didn't realize before I started to use the photosynthesis and respiration minds-on activities that these lessons were designed for classrooms with limited internet access, and I wanted to add my two-cents about that. I do have regular internet access in a computer lab or with a laptop cart, and most students now have a mobile device that they can share with others. Web activities and quests are great, but I find that with these minds-on activities (I like that term a lot), my students are more likely to read carefully, study diagrams, refer to previous lessons, and are overall more engaged than if they were using screen time to accomplish similar learning tasks. I use these activities using a POGIL style approach, and my students have a much deeper understanding of these difficult topics - and they enjoy the opportunity to work on them together. I would encourage more teachers who are concerned about students obtaining a deep understanding of biological topics to steer clear of flashier web based applications and make some of these resources work for their classrooms (thank you for publishing the resources in Word so it is easier to do this). I wish I had found them years ago!

How do plants and Photosynthesis and Cellular Respiration.

In the first part of this activity, students learn how to use the floating leaf disk method to measure the rate of net photosynthesis (i.e. the rate of photosynthesis minus the rate of cellular respiration). They use this method to show that net photosynthesis occurs in leaf disks in a solution of sodium bicarbonate, but not in water. Questions guide students in reviewing the relevant biology and analyzing and interpreting their results. In the second part of this activity, student groups develop hypotheses about factors that influence the rate of net photosynthesis, and then each student group designs and carries out an investigation to test the effects of one of these factors.

Perhaps a few hundred million years after the first mitochondrion appeared, as the oceanic oxygen content, at least on the surface, increased as a result of oxygenic photosynthesis, those complex cells learned to use oxygen instead of hydrogen. It is difficult to overstate the importance of learning to use oxygen in respiration, called . Before the appearance of aerobic respiration, life generated energy via and . Because oxygen , aerobic respiration generates, on average, about per cycle as fermentation and anaerobic respiration do (although some types of anaerobic respiration can get ). The suite of complex life on Earth today would not have been possible without the energy provided by oxygenic respiration. At minimum, nothing could have flown, and any animal life that might have evolved would have never left the oceans because the atmosphere would not have been breathable. With the advent of aerobic respiration, became possible, as it is several times as efficient as anaerobic respiration and fermentation (about 40% as compared to less than 10%). Today’s food chains of several levels would be constrained to about two in the absence of oxygen. Some scientists have and oxygen and respiration in eukaryote evolution. is controversial.
