Lesson Worksheet: Photosynthesis Science
In this worksheet we will practice outlining the process of photosynthesis, stating where it occurs, and describing how a plant obtains the materials that it needs.
Q1:
What type of organism makes its own food by photosynthesis?
- AParasite
- BDecomposer
- CProducer
- DScavenger
- EConsumer
Q2:
Complete the following: Plants make their own food by a process called .
- Achemosynthesis
- Bconsumption
- Crespiration
- Dphotosynthesis
- Edigestion
Q3:
Which reactant of photosynthesis enters the leaf through tiny pores during the day?
- ACarbon dioxide
- BMinerals
- CLight
- DOxygen
- EWater
Q4:
What is the energy source used by algae and green plants to make their own food?
- ASound
- BLight
- CChemicals
- DHeat
Q5:

Q6:
The glucose made by photosynthesis is converted into many other products that are needed for the growth of a producer.
What word describes the organic substances in a producer that are made by photosynthesis?
- ABiofuel
- BBiomass
- CBiomatter
Q7:
The figure shows a leaf. Why is it green?
- AIt contains chlorophyll to absorb oxygen.
- BIt contains hemoglobin to absorb sunlight.
- CIt contains chlorophyll to absorb sunlight.
- DIt contains hemoglobin to absorb carbon dioxide.
- EIt contains pigments to protect against UV damage.
Q8:
The figure shows a cross section of a plant root.
What is the function (job) of the xylem tissue shown in the figure?
- AIt transports minerals made in photosynthesis down from the leaf.
- BIt transports carbon dioxide up to the leaf to use in photosynthesis.
- CIt transports glucose made in photosynthesis down from the leaf.
- DIt transports oxygen up to the leaf to use in photosynthesis.
- EIt transports water up to the leaf to use in photosynthesis.
Q9:
Which organism (A, B, C, D, or E) is not a producer?
- AE
- BB
- CC
- DA
- ED
Q10:
The figure shows the structure of a leaf. The veins transport materials into and out of the leaf.
What is the correct movement of substances through leaf veins when the plant is photosynthesizing?
| Through the Veins and into the Leaf | Out of the Leaf and through the Veins | |
|---|---|---|
| A | Water | Glucose |
| B | Carbon dioxide | Oxygen |
| C | Water | Oxygen |
| D | Carbon dioxide | Water |
| E | Oxygen | Glucose |
- AA
- BC
- CE
- DD
