Regents questions photo 1

The green aquatic plant in the picture was exposed to light for several hours. Which gas would most likely be found in the greatest amount in the bubbles?

• Carbon Dioxide

• oxygen

• nitrogen

• ozone

What organelle is A?

• Ribosome

• mitochondria

• vacuole

• Chloroplast

What is a heterotroph?

• producer

• consumer

• protein

• ribosome

What is an autotroph?

• producer

• consumer

• protein

• Ribosome

For the process of autotrophic nutrition, the arrow labeled A would most likely represent the direction of movement of

• oxygen, glucose, solar energy

• glucose, water, and heat energy

• carbon dioxide, water, and solar energy

• carbon dioxide, oxygen, and heat energy

Which process illustrates a feedback mechanism in plants?

• Chloroplasts take in more nitrogen, which increase the rate of photosynthesis

• Chloroplasts release more oxygen in response to decreased rate of photosynthesis

• Guard cells change the size of leaf openings regulating the exchange of gases

• Guard cells release oxygen from the leaf at night
