Question

drawing and labeling photosynthesis and cellular respiration
directions:
on the back of this page, draw and label a diagram that shows 1 organism photosynthesizing and 1 organism undergoing cellular respiration. do research online to pick a specific autotroph and heterotroph combination (the more unique the better!). in your diagram, label everything being used and produced by each organism. where does your plant get energy from? what about your animal? what waste materials do these organisms produce? where do they go? use arrows to show the flow of materials from one organism to the other. your diagram should clearly display the relationship between photosynthesis and cellular respiration.
key words:
be sure to label all of the following terms in your diagram

• light energy
• co2 (carbon dioxide)
• o2 (oxygen)
• h2o (water)
• atp
• c6h12o6 (glucose)
• autotroph
• heterotroph
• photosynthesis
• cellular respiration

questions:

1. describe the relationship between cellular respiration and photosynthesis.
2. what is the ultimate source of energy for all life on earth?
3. what is the difference between autotrophs and heterotrophs?
4. where in the cell does photosynthesis take place? where does cellular respiration take place?

Explanation:

1. Photosynthesis uses light energy to convert carbon - dioxide and water into glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon - dioxide, water, and ATP. They are opposite processes.
2. The sun is the ultimate source of energy for all life on Earth. It provides light energy used in photosynthesis, which starts the energy flow in ecosystems.
3. Autotrophs can produce their own food (organic compounds) from inorganic substances, usually through photosynthesis. Heterotrophs cannot produce their own food and must consume other organisms for energy.
4. Photosynthesis takes place in chloroplasts. Cellular respiration takes place in the cytoplasm and mitochondria.

Answer:

1. They are opposite processes. Photosynthesis makes glucose and oxygen from carbon - dioxide and water using light energy, while cellular respiration breaks down glucose and oxygen to release energy as ATP, producing carbon - dioxide and water as by - products.
2. The sun.
3. Autotrophs produce their own food from inorganic substances (e.g., through photosynthesis), while heterotrophs obtain food by consuming other organisms.
4. Photosynthesis: chloroplasts. Cellular respiration: cytoplasm and mitochondria.
