Answer key
1. What are the products of photosynthesis?
A. Water and Glucose
B. Glucose and Oxygen -answer
C. Carbon dioxide, ATP, and Water
D. Carbon dioxide and Oxygen
Answer Explanation: Photosynthesis is the process in which plants use carbon dioxide, water, and light energy to produce glucose and oxygen.
2. What are the tiny disk-like structures in the chloroplast called?
A. Thylakoid - answer
B. Mitochondria
C. DNA
D. Disk
Answer Explanation: Inside the chloroplast, there are tiny disk-shaped structures called thylakoids. Thylakoids are an important part of photosynthesis because they contain a pigment called chlorophyll that catches the sunlight energy.
3. How many stages are there in cellular respiration?
A. Five
B. Twenty
C. Three
D. Two -answer
Answer Explanation: There are two stages in the process of photosynthesis with the first being light-dependent reactions that uses light energy to create two molecules (ATP, NADPH) necessary for photosynthesis. The second stage of photosynthesis is light-independent reactions that are chemical reactions that transform compounds into glucose.
4..Explain the purpose of ATP in the cell
Answer Explanation: The purpose of ATP in the cell is to transport energy that is used for metabolic activities. ATP is a very important for the cell without it, the cell wouldn’t be able to survive.
2. Explain the process of how ATP is transformed into ADP
Answer Explanation: ATP is transformed into ADP (adenosine diphosphate) through a process called hydrolysis. Hydrolysis is when a phosphate group is taken away by the breaking of a bond. Then, energy is released and ATP is then converted into ADP.
