FSQ 8

Front

Which of the following statements best describes the process of photosynthesis?
A) Carbon dioxide and water combine to form glucose and oxygen.
B) Carbon dioxide and glucose combine to produce energy and water.
C) Carbon dioxide, glucose, and water are released to produce energy.
D) Carbon dioxide and water are released when glucose and oxygen combine.

Back

Carbon dioxide and water combine to form glucose and oxygen.

Answer explanation

A) is correct because photosynthesis involves carbon dioxide and water combining to produce glucose and oxygen, which is the fundamental process in plants for converting light energy into chemical energy.

How would placing a plant in a dark room for 24 hours affect the rate of photosynthesis?

Back

The rate of photosynthesis would decrease and the plant would take in less carbon dioxide.

Answer explanation

Placing a plant in a dark room prevents it from photosynthesizing, leading to a decrease in the rate of photosynthesis. Consequently, the plant would take in less carbon dioxide, making D the correct choice.

What causes the bubbles to appear during photosynthesis?

Back

Photosynthesis is occurring and bubbles of oxygen gas are being released into the surrounding area.

Answer explanation

The correct choice explains that during photosynthesis, plants release oxygen gas as a byproduct. This process creates bubbles of oxygen that escape into the surrounding area, which is why bubbles appear.

Which statement about cellular respiration is true?
Options:
1. Oxygen is a waste product of cellular respiration in both plants and animals.
2. Oxygen is a waste product of cellular respiration in plants, but not in animals.
3. Carbon dioxide is a waste product of cellular respiration in both plants and animals.
4. Carbon dioxide is a waste product of cellular respiration in plants, but not in animals.

Back

Carbon dioxide is a waste product of cellular respiration in both plants and animals.

Answer explanation

The correct statement is that carbon dioxide is a waste product of cellular respiration in both plants and animals. While plants use oxygen for respiration, they also produce carbon dioxide as a byproduct.

How would the amount of gas released differ during exercise compared to rest?

Back

More carbon dioxide would be released when exercising than when at rest.

Answer explanation

During exercise, cellular respiration increases to meet energy demands, resulting in more carbon dioxide being produced as a byproduct. Therefore, more carbon dioxide is released when exercising than when at rest.

What do Kendrick's cells do during cellular respiration?

Back

His cells use oxygen to break down food molecules to release energy.

Answer explanation

During cellular respiration, Kendrick's cells use oxygen to break down food molecules, releasing energy necessary for his exercise activities like running and lifting weights.
