Total questions: 13
Worksheet time: 7mins
What are the reactants for Photosynthesis?
Water and Glucose
Water and Carbon Dioxide
Oxygen and Glucose
Water and Oxygen
If plants were placed in an environment with more Carbon Dioxide, predict what would happen to the rate of photosynthesis
Photosynthesis would stop
The rate would decrease
The rate would increase
The rate would not change
Where do trees get most of their mass?
Water
Soil
Oxygen
Carbon Dioxide
Define Autotroph
Organisms that get their energy from other organisms
Organisms that create their own food
Organisms that eat other organisms
an example are mammals
What is the goal of photosynthesis?
To make oxygen for other organisms
To get rid of extra carbon dioxide in the atmosphere
To create glucose
To feed organisms higher in trophic levels
What are the products of photosynthesis?
Water and Glucose
Oxygen and Glucose
Carbon Dioxide and Water
Water and Oxygen
What occurs in the light dependent step of photosynthesis?
Plants convert carbon dioxide into glucose using ATP and NADPH
Plants convert oxygen into water using hydrogen ions and electrons
Light energy is converted into chemical energy by splitting water and creating NADPH and ATP molecules
Light energy is absorbed by the pigment caritanoid within the chloroplasts
What occurs in the light independent step of photosynthesis
ADP and NADP are converted into ATP and NADPH
Light is needed to split water into oxygen, hydrogen ions and electrons
Light energy is absorbed by chlorophyll in the chloroplasts to create ATP
ATP and NADPH from step one are used to build glucose from carbon dioxide
Where does the light independent reaction occur?
In the membrane of the chloroplast
In the Grana
In the Stroma
In the Thylakoids
Where does the light dependent reaction occur?
In the Stroma
In the Thylakoids
In the fluid filled portion of the chloroplasts that surround the thylakoids
In the cytoplasm
What is the equations for photosynthesis?
Water + Glucose --> Carbon Dioxide + Oxygen
Glucose + Oxygen --> Carbon Dioxide + Water
Carbon Dioxide + Water --> Glucose + Oxygen
Carbon Dioxide + Glucose --> Oxygen + Water
How are photosynthesis and Cellular Respiration Related?
The both create glucose
All organisms perform both processes
They have opposite equations
They are not related
Which of the following is NOT a reason why plants are essential for Life on Earth
Plants produce carbon dioxide which keeps the globe warm
They produce glucose and oxygen, which are essential for heterotrophs to survive
Plants produce the reactants for cell respiration
Plants form a vital part of an ecosystem: they are the primary producers
