Photosynthesis Basics
Complete the word equation: Carbon dioxide + water + energy → glucose + ________
Oxygen
During photosynthesis, carbon dioxide and ______ are converted into glucose and oxygen.
Water
Glucose can be used in respiration to release ______.
Energy
All living organisms carry out this process to release energy.
Respiration
What causes the green color of a cactus stem?
Chlorophyll
A plant with variegated leaves is kept in dim light. The white areas begin turning green. Why is this an advantage?
More chlorophyll is produced, allowing more photosynthesis in low light conditions.
What type of energy is needed for photosynthesis?
Light energy
The energy needed for photosynthesis is ______ energy.
Light
Glucose can be stored as ______.
Starch
Is respiration aerobic or anaerobic when oxygen is used?
Aerobic
Why is a green stem an advantage for a cactus?
It can photosynthesize
If temperature decreases, what happens to the rate of photosynthesis?
It decreases.
Photosynthesis takes place mainly in what part of the plant cell?
Chloroplasts
Chlorophyll can be found inside the ______.
Chloroplast
Glucose can be converted into cellulose to strengthen the ______.
Cell wall
Complete the equation: 6 O₂ + C₆H₁₂O₆ → ______ + ______
6 H₂O + 6 CO₂
What is a group of tissues working together called?
Organ
Complete the paragraph using these words:
carbon, chlorophyll, light, oxygen, starch, water

Glucose can be converted into ______ for storage.
Starch
Name one way plants use glucose besides respiration.
Storage as starch, making cellulose, making proteins
