Photosynthesis
Al Bawadi School
Why do plants need sunlight?
Photosynthesis is a series of chemical reactions that plants use to make their own food.
Plants use photosynthesis to produce oxygen

16
Multiple Choice
Through the process of photosynthesis, a century plant uses sunlight to make food. The equation below shows this process.
Light Energy + Carbon Dioxide + Water → Glucose + Oxygen
What happens to the light energy that the century plant uses for photosynthesis?
The light energy is destroyed during the chemical reaction.
The light energy is released into the atmosphere as water vapor.
The light energy is transformed into chemical energy in glucose.
The light energy is transformed into thermal energy and oxygen.
17
Multiple Choice
Carbon cycles among Earth's air, ground, and organisms. The diagram models part of the carbon cycle. Which of the following best describes the process that occurs at arrow X?
Plants release carbon dioxide into the air through decomposition.
Plants take in carbon dioxide from the air to perform photosynthesis.
Plants release carbon dioxide into the air as a waste product
of photosynthesis.
Plants release carbon dioxide into the air as a waste product of
cellular respiration.
18
Multiple Choice
Which of the following correctly combines the organelle with its function during photosynthesis?
vacuole contains chlorophyll which absorbs nutrients
chloroplast contains chlorophyll which absorbs sunlight
mitochondria converts energy into food
cytoplasm converts food into energy
19
Multiple Choice
One living plant leaf, still attached to the plant, is placed into a cup and covered with water. A light source is placed so that it shines into the cup on the leaf. In moments, bubbles appear on the surface of the leaf. Which statement explains what causes the bubbles to appear?
Photosynthesis is occurring and the bubbles of carbon dioxide gas are being released by the plant.
Photosynthesis is occurring and bubbles of oxygen gas are being released by the surrounding area and absorbed into the plant.
Photosynthesis is occurring and bubble of oxygen gas are being released from the plant.
Photosynthesis is occurring and bubbles of air are entering the water from the area around the plant.
