What All plants use photosynthesis, so they all need some sunlight.

How does this investigation demonstrate that plants give off oxygen during  photosynthesis?

Photosynthesis takes place in all plants that contain chlorophyll.

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .

The process by which plants use light energy to make glucose is called photosynthesis.

Photosynthesis is the procedure all plants go through to make food.

Activity 4.1 is the first part of the Explanations Phase of the instructional model (going down the triangle) for cellular respiration. Students construct molecular models of the chemical change that took place during the investigation to help them develop an atomic-molecular explanation for how plants get energy to move. Plants use the energy released from cellular respiration to grow and function (for biosynthetic processes and other cellular functions) as well as to move. Plants engage in cellular respiration in both the light and the dark. If your students did cellular respiration molecular modeling as part of the Animals or Decomposers Units, and did well on questions about cellular respiration on the pretest, you may want to skip the cellular respiration modeling steps in this Activity.

Background Knowledge: Photosynthesis is the process by which plants make their own food.

Butwhat happens at night when there is no sunlightwhich is needed in photosynthesis? Interestingly,in order to maintain their metabolism and continuerespiration at night, plants must absorb oxygenfrom the air and give off carbon dioxide (which isexactly what animals do). Fortunately for all ofus oxygen breathers, plants produce approximatelyten times more oxygen during the day that whatthey consume at night.

The process takes place in the leaves of green plants, this is what the leaves are for.


What gas do plants give off during photosynthesis

Most of the energyreleased both by the burning of fossil fuels and by the metabolism ofliving cells is given off as heat and must be replaced by thecontinued input of radiant energy from the Sun.The principal organic products of plant photosynthesis arecarbohydrates.

produced in photosynthesis, green plants need ..

Immediatelyafter exposure to 14CO2, the plant's photosynthetic tissue iskilled by immersing it in boiling alcohol, and all of the biochemical reactions cease.

Photosynthesis is the process by which plants, ..

There are multiple pathways from which to choose when teaching the carbon-transforming processes in Lessons 4 and 5. You may choose to go in the order presented here. You may choose to follow an order that makes more sense instructionally to you. Or you may choose to go in an order based on the types of questions your students are asking. Please see the document or the Student Challenges and Teacher Choices in the Plants Unit document for clarification in making this instructional decision. Remember that if you choose a different order than what is presented here, you will need to be aware of what you have and have not yet taught your students, and you may want to make small adjustments to the activities accordingly.

plants only use the carbon during photosynthesis

A note on the chemical change formulas for photosynthesis and cellular respiration. Activities 4.1 and 4.3 simplify the full story of what happens to matter during the multi-step processes of cellular respiration and photosynthesis. For a more detailed account, see ..
