Answer 1

Here are the answers to your questions based on the characteristics of prokaryotic and eukaryotic cells, plant and animal cells, photosynthesis, anaerobic cellular respiration, and the functions of stomata:

1. Which of the following is a true statement about the differences between prokaryotic and eukaryotic cells?

   • Eukaryotic cells have a nucleus, but prokaryotic cells do not. (This statement is true.)

2. Which of the following cell structures are present in PLANT cells but NOT animal cells?

   • Chloroplasts. (Chloroplasts are involved in photosynthesis and are found in plant cells, but not in animal cells.)

3. Which of the following correctly identifies the products and reactants of photosynthesis?

   • Reactants: carbon dioxide, water and light; Products: glucose and oxygen. (This is the correct equation for photosynthesis.)

4. Anaerobic cellular respiration can take place in the absence of:

   • Oxygen. (Anaerobic means "without oxygen," so anaerobic respiration occurs in its absence.)

5. What is the primary function of stomata in plants?

   • Regulate gas exchange. (Stomata are openings on the surfaces of leaves that allow for the exchange of gases such as oxygen and carbon dioxide.)
