Correct Answer
A. 2Explanation
Starch molecules in a maple tree are made from simple sugars that originally entered the tree from the external environment. This is because trees undergo photosynthesis, where they convert sunlight, water, and carbon dioxide into glucose, a type of simple sugar. Glucose is then converted into starch and stored in various parts of the tree, such as the roots or trunk, for later use as an energy source. Therefore, option 2, simple sugars, is the correct answer.Rate this question:

Photosynthesis is an important process. Discuss photosynthesis and explain its importance to an organism. In your answer, be sure to: • identify the organelle where this process occurs [1]
Correct Answer
chloroplast
chloroplastsExplanation
Photosynthesis is a vital process for organisms as it is responsible for converting sunlight, water, and carbon dioxide into glucose and oxygen. This process occurs in the organelle called the chloroplast. Chloroplasts contain chlorophyll, a pigment that captures sunlight, enabling the synthesis of glucose through a series of chemical reactions. Glucose serves as the primary energy source for organisms and is essential for growth, reproduction, and overall survival. Additionally, photosynthesis produces oxygen, which is released into the atmosphere, maintaining the balance of gases necessary for life on Earth.Rate this question:

Photosynthesis is an important process. Discuss photosynthesis and explain its importance to an organism. In your answer, be sure to: • identify the organelle where this process occurs [1] • identify 1 of the 3 raw materials necessary for this process [ 1 ]
Correct Answer
carbon dioxide
water
sunlight
sun
H2O
the sunExplanation
Photosynthesis is a vital process in which plants and some other organisms convert sunlight, carbon dioxide, and water into glucose and oxygen. This process occurs in the chloroplasts, which are organelles found in plant cells. One of the three raw materials necessary for photosynthesis is carbon dioxide, which is obtained from the atmosphere. Water, another raw material, is absorbed by the roots of plants from the soil. Lastly, sunlight, or the energy from the sun, is crucial for photosynthesis to occur. Without photosynthesis, plants would not be able to produce food for themselves and other organisms, and the oxygen necessary for respiration would not be released into the atmosphere.Rate this question:

Photosynthesis is an important process. Discuss photosynthesis and explain its importance to an organism. In your answer, be sure to: • identify one energy-rich molecule that is produced by this process [1]
Correct Answer
glucoseExplanation
Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. Glucose is an energy-rich molecule that serves as a primary source of fuel for plants and other organisms. It is used in cellular respiration to produce ATP, the energy currency of cells. Additionally, glucose is used to synthesize other organic molecules, such as starch and cellulose, which are important for plant growth and development. Therefore, glucose produced through photosynthesis is crucial for the survival and functioning of organisms that rely on plants for food or oxygen.Rate this question:

Photosynthesis is an important process. Discuss photosynthesis and explain its importance to an organism. In your answer, be sure to: • state the gas produced by this process [1]
Correct Answer
O2
oxygenExplanation
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. The gas produced by this process is oxygen (O2). Oxygen is vital for the survival of organisms as it is required for respiration, the process by which cells convert glucose into energy. Without photosynthesis and the production of oxygen, organisms would not be able to carry out respiration and generate the energy needed for growth, reproduction, and other essential life processes. Therefore, photosynthesis is crucial for sustaining life on Earth.Rate this question:

A green plant is kept in a brightly lighted area for 48 hours. What will most likely occur if the light intensity is reduced slightly during the next 48 hours? (1) Photosynthesis will stop completely. (2) The rate at which nitrogen is used by the plant will increase. (3) The rate at which oxygen is released from the plant will decrease. (4) Glucose production inside each plant cell will increase.

Correct Answer
A. 3Explanation
If the light intensity is reduced slightly during the next 48 hours, it is most likely that the rate at which oxygen is released from the plant will decrease. This is because light is necessary for the process of photosynthesis, which produces oxygen as a byproduct. Therefore, if the light intensity is reduced, the plant will have less energy to carry out photosynthesis, resulting in a decrease in the rate of oxygen release.Rate this question:

Correct Answer
A. 2Explanation
Autotrophs, such as plants, use the process of photosynthesis to store energy in glucose. During photosynthesis, autotrophs convert sunlight, carbon dioxide, and water into glucose and oxygen. This process allows autotrophs to capture and store energy from the sun in the form of glucose, which can be used later for cellular respiration or other metabolic processes. Therefore, the correct answer is 2) photosynthesis.Rate this question:

Correct Answer
A. 4Explanation
Autotrophic nutrition is the process that usually uses carbon dioxide molecules. Autotrophs, such as plants, use carbon dioxide during photosynthesis to produce their own food. They convert carbon dioxide into organic compounds, such as glucose, using energy from sunlight. This process is essential for the survival and growth of autotrophs, as it allows them to obtain the necessary carbon for their metabolic activities.Rate this question:
